Basic Comparison of T Shape and AT Shape T5 / T10 (Standard Type): The tooth root is thin and designed for light loads. Stress concentrates during sudden stops, making it prone to skipping and tooth breakage. AT5 / AT10 (High Load Type): The tooth root is thickened, improving torque transmission by 30-50% at the same pitch ratio. It is optimal for low backlash, high precision forward and reverse rotation, and multi-axis robots. Points for Operation and Improvement Mixing is not allowed: Due to different tooth groove shapes, belts and pulleys must be replaced simultaneously. Change to the same pitch is recommended: When torque is insufficient, changing to the same pitch AT5 to increase strength without altering installation space is optimal rather than enlarging to T10. Improving Precision: Reducing backlash prevents response delays during frequent forward and reverse rotations. *The content of this article is based on information from specific cases, and actual application effects may vary depending on industry characteristics, specification requirements, and usage environments. Please use it as reference information in advance.

■ Trapezoidal Teeth (General Torque: MXL/XL/L/H) Stress concentrates at the tooth root, making it prone to fatigue failure and tooth jumping during sudden starts or high loads, thus suitable for lightweight equipment under medium to low loads. ■ Arc Teeth (High Torque: S-M/P-M) Load is evenly distributed across the entire tooth surface, allowing for a torque capacity of more than twice. Deep grooves prevent tooth jumping during forward and reverse rotation, achieving low backlash and high rigidity, making it ideal for robots and CNC servo axes. ■ Practical/FAQ Points for Replacement: Changing from XL to S3M, etc., requires simultaneous replacement of the belt and pulley due to differences in pitch and tooth shape. S-M vs P-M: S-M is standard arc (quiet), while P-M is flat-top arc (for high-precision servo positioning). Additional Processing: When machining shaft holes and keyways, pay attention to coaxiality and shear strength to prevent wear due to eccentricity.

"Four Major Longevity Genes" of Precision Grade Guide Posts Abnormal noise and cumulative errors are caused by insufficient rigidity of the guide post assembly. Handway extends mold life by 3 to 5 times. 1. SUJ2 Bearing Steel: High fatigue strength that does not bend even after tens of millions of reciprocations. 2. Hardening & Sub-Zero: Hardness HRC 58-62. Residual stress is eliminated, resulting in zero dimensional change. 3. Super Finishing (<Ra 0.1): Minimizes friction heat. The black oxide coating absorbs oil film and prevents wear. 4. 2µm Tolerance & JIS Grade 5 Balls: "Zero Clearance" guidance with aluminum retainers and high sphericity steel balls. FAQ Highlights Q1. Reason for Sub-Zero: Prevents aging deformation and maintains 2µm tolerance. Prevents seizure due to thermal expansion. Q2. Effect of Black Oxide: The fine pores on the surface absorb and retain oil, maintaining the oil film even with high-frequency operation. Q3. Advantages of Aluminum Retainers: High rigidity without embrittlement from oil. Significantly reduces impact force due to inertia. Q4. Prevention of Eccentric Breakage: "Chamfer f8" makes centering easy. Confirms coaxiality and avoids excessive pushing.

Despite using the same drawings and contractors, there have been occasional issues with the assembly of retaining rings being either too loose or too tight. All parts passed inspection within the drawing dimensions (Φ20mm). The cause was that the drawings did not specify fit tolerance grades, leading to the dimensions of the shaft and hole drifting within the tolerance range, which caused the tightness to become erratic due to cumulative differences. To resolve this, it is necessary to specify tolerance grades during the design phase and to establish a range for tightness. Gap fit (H7/g6, etc.): The tolerance range of the shaft is below that of the hole, creating a gap. It can be disassembled without load. Suitable for rotating or movable parts and areas that are frequently disassembled. Interference fit (H7/k6, etc.): The tolerance ranges partially overlap, resulting in a very small gap or interference. It is assembled using press-fitting or light tapping, preventing misalignment with high precision. The drawings should include not only symbols but also the upper and lower limits of dimensional tolerances, which should be managed by the contractors. FAQ Q1: Mixing? Mixing different shaft stages of the same axis is possible depending on functionality. Q2: Readjustment? Disassembling an interference fit is not recommended as it can damage the surface and change the tolerances. A gap fit is recommended. Q3: What do the numbers mean? IT tolerance grades. The smaller the number (g6), the higher the precision and uniformity, but costs will rise.

In automated equipment, shaft collars are responsible for preventing parts from coming loose and for axial positioning. The standard products feature a precise "gap-fit" design that does not damage the rod and generates high holding power during set screw tightening. "End Face Squareness Geometric Tolerance" that affects precision and lifespan The end face squareness geometric tolerance on the drawing (0.02|A) is set to keep runout within 20 micrometers. Poor quality products that have not been inspected for geometric tolerance (with squareness exceeding 50 micrometers) generate diagonal force components, leading to bending of the guide rod and eccentric loads on the bearings. As a result, vibration and heat generation increase, significantly reducing the machine's MTBF (Mean Time Between Failures). Handway's Strengths We thoroughly manage geometric tolerances that comply with international standards and provide top-class products made from the following materials: S45C SUS304 Aluminum alloys, etc. Upgrades through additional processing For high-vibration environments, we recommend additional processing such as D-cuts or pilot hole machining on the rod. The tips of the set screws can mesh together, allowing for a reliable upgrade in fixation. For optimal solutions, please consult Handway.

In automated equipment, the stability of linear mechanisms affects the lifespan of the machinery. However, there are many cases where only the dimensions are prioritized when selecting linear shafts, overlooking the "depth of high-frequency hardening." Linear shafts are subjected to high-frequency rolling loads from steel balls, making it crucial to balance wear resistance and breakage resistance. The key to this is the "hard shell soft core" structure. The outer hardened layer prevents wear due to its high hardness (SUJ2: HRC58 and above, SUS440C: HRC56 and above), while the inner soft core absorbs shocks and prevents brittle fracture. The hardening depth is optimized to about 0.5 to 1.0 mm depending on the outer diameter. If it is too shallow, flaking can occur; if too deep, the risk of fracture due to reduced toughness increases. Additionally, selection must be based on dynamic loads and vibration environments, and secondary processing after heat treatment is not recommended as it can cause deformation and micro-cracks.

The shaft holder is a component that supports stable linear motion and axial loads. If the selection of materials and surface treatments is incorrect, it can lead to rust, contamination, and seizure. The characteristics of the five main standards are as follows: SS400 + Black Dye (Rust Prevention: Moderate): Forms an extremely thin chemical oxidation film. Maintains H7 tolerance without thickness variation. The matte black color is less reflective, making it ideal for AOI optical inspection. SS400 + ENP (Rust Prevention: Good): Nickel-phosphorus alloy layer is deposited through chemical reduction. Provides uniform coverage even in deep holes, with excellent hardness and wear resistance, making it ideal for humid environments. SUS304 Stainless Steel (Rust Prevention: Excellent): Coating is unnecessary due to a unique passive film. No peeling due to friction, making it an essential standard for clean rooms, medical applications, and food machinery. A6061 + Anodized (Rust Prevention: Good): Generates a hard ceramic layer. One-third the weight of steel, reducing motor load and increasing acceleration, making it ideal for EOAT. A6061 + Black Anodized (Rust Prevention: Good): Adsorbs black dye into fine pores for a matte finish. Balances lightweight design with low reflectivity, making it ideal for semiconductor inspection equipment.

In the design of precision machinery and micromechanisms, it is important to achieve optimal linear motion strokes within limited space. The selection of microcomponents significantly impacts not only size but also operational accuracy and maintenance cycles. To improve reliability, understanding the relationship between contact length (L1: guide bushing, L2: steel ball retainer) and stroke is essential. HEADWAY offers the following two types according to design needs. Open-type guide bushings ensure flexible strokes by maintaining L2≥L1, with S=2×(L2−L1). Closed-type guide bushings enhance stability with a structure where L1>L2, with S=2×(L1−L2). In terms of performance, they can handle high-frequency operations of 30 million to 50 million cycles, and the optimized steel ball circulation structure increases operational efficiency to about three times that of standard products. The low-wear design maintains a lifespan of 2 to 3 years, contributing to reduced maintenance costs. Additionally, the SUS440C stainless steel specification allows for compatibility with special environments such as oil-free (food industry), anti-volatile (optical equipment), and high vacuum (semiconductors). Selecting the appropriate guide bushing and adopting components based on actual measurement data are key to maximizing the accuracy and long-term productivity of the equipment.

Assembly troubles with positioning pins are largely due to the geometry of the ends. Choosing the appropriate chamfer (C face) or radius (R face) can make a significant difference in assembly efficiency and component lifespan. C face (Chamfer): Excellent for guiding initial contact and correcting position, it allows for smooth guidance. It reduces seizing and deformation, and minimizes positional misalignment during press-fitting. It pairs well with ANSI standard hardened steel, making it ideal for high-precision press fits and improving stability in automated lines. R face (Radius): The curved surface disperses stress, reducing the risk of damage to hole walls and fatigue cracks. It is suitable for ISO/DIN standard non-hardened stainless steel, and is ideal for slip fits, frequent assembly and disassembly, and use with soft materials like aluminum and plastics. It ensures durability and stability even with long-term use. Selection summary: For efficiency, choose C face; for durability, choose R face; for critical structural components or high-precision equipment, a combined design of C + R is appropriate.
