The HBN type ball screw with ball retainer is an optimal ball screw for use under high load conditions, designed to eliminate mutual friction and collisions between balls during high-load movement, improve grease retention, and enhance lubrication performance. Additionally, the adoption of the ball retainer enables longer lifespan, reduced noise, and lower torque fluctuations under high load conditions. Furthermore, it allows for use at a DN value of 130,000 (compared to the previous 70,000) due to a ball circulation method suitable for high-speed use.

• nut

The rotary ball screw is a nut-rotating ball screw unit where the ball screw nut and support bearing are integrated into a single structure. The support bearing is an angular bearing with a contact angle of 60° and a high number of balls, providing significant axial rigidity. The BLR type is available in specifications for precision ball screws and rolled ball screws.

• nut

The ball screw and spline are designed with ball screw grooves and ball spline grooves crossing on a single shaft, and each ball screw nut has a dedicated support bearing directly incorporated into its outer circumference, forming a stroke and rotation unit. By rotating or stopping the ball screw nut and spline outer cylinder, it is possible to achieve rotational motion, linear motion, and spiral motion on a single axis. This is ideal for applications such as the Z-axis of a SCARA robot, assembly robots, auto loaders, and ATC devices in machining centers, where a combination of rotational and linear motion is required.

The Super Silent Cable Chain, Silebear KSL type / KSH-L type, features a linkless structure with no joints, achieved through a special nylon continuous integral molding process. The linkless structure eliminates the play and gaps typically found in link-type connections, resulting in reduced noise from the link sections during movement and demonstrating quietness during high-speed operation. Additionally, due to the linkless design, there is less wear and dust generation from the link sections, making it suitable for use in clean rooms.

• Chains and sprockets

The link ball uses high-precision bearing steel balls in the spherical part, and after forming the holder by die-casting, the shank part is specially welded. This innovative manufacturing method allows the mirror surface of the steel ball to be transferred to the spherical part of the holder, resulting in full surface contact and smooth operation with minimal clearance.

• Other machine elements

The ball spline is a revolutionary linear motion system that allows torque transmission while a ball, incorporated into the spline nut, moves smoothly in a straight line along the rolling surface of a precisely ground spline shaft. Moreover, unlike conventional structures, it provides preload with a single spline nut, enabling high performance in harsh applications where vibration and impact loads occur, in areas requiring high precision positioning, and in situations demanding high-speed motion performance. Additionally, when used as a substitute for linear bushes, it has a rated load that is several times greater than that of the same shaft diameter, allowing for a compact design. This makes it usable even in cases where overhang loads and moments are applied, resulting in high safety and long lifespan.

■Seismic Isolation of Buildings Seismic isolation is achievable even for lightweight and tower-shaped buildings, which were difficult to implement with conventional devices, using THK's seismic isolation devices. The buildings themselves are designed as usual, utilizing a flexible seismic isolation structural system. - Realization for Various Buildings THK's seismic isolation devices can operate even with lightweight buildings. They enable seismic isolation not only for traditionally possible heavy buildings but also for skyscrapers, wooden single-family homes, and lightweight steel buildings. - Free Period Setting The direct rolling bearing CLB has a low friction coefficient (0.0012 to 0.009) and minimal variation (below 0.002), allowing for the setting of restoration and damping mechanisms, which makes it possible to achieve long periods (over 5 seconds) for buildings that were previously difficult to accommodate. THK's seismic isolation devices utilize its core products, including LM guides. These devices, created as an application of products infused with trust, proven results, originality, and technical prowess, embody THK's unwavering confidence.
