High Positioning Accuracy Linear guides have very low friction resistance during motion, allowing the table to be driven with minimal power compared to sliding friction. Due to the low friction resistance, the frictional heat generated during motion is also reduced. Compared to conventional sliding friction, the wear on the rolling contact surfaces of the rails is significantly decreased, maintaining high positioning accuracy and low wear even during prolonged operation. High Rigidity The block and rail have a circular arc groove shape, allowing them to bear loads from all directions. With a DF structure, they exhibit excellent error absorption capabilities. By applying pre-load, it is possible to achieve high rigidity. Easy Maintenance In the case of sliding guides, it is necessary to constantly form an oil film on the sliding surfaces and to force a large amount of lubricating oil, which requires significant time and cost for maintenance. Linear slides only require regular lubrication, making maintenance easy while also maintaining the machine's operational accuracy. High Speed The block, rail, and balls have a rolling contact structure, resulting in a low coefficient of friction and minimal frictional heat generation. Machines can operate with small power, leading to significant energy savings, making them more suitable for high-speed motion compared to sliding guides.

High Reliability Ball screws are products based on years of technology accumulated from materials, and they possess high reliability based on a strictly managed quality assurance system throughout heat treatment, manufacturing, and shipping inspections. Smooth Movement Ball screws have a high efficiency of 30% or less of the required torque compared to sliding screws. This allows for easy conversion between linear and rotational motion. They can even maintain smooth movement characteristics when preloaded. No Backlash, High Rigidity Using a Gothic (Gothic arch) groove shape, ball screws can be easily rotated with very small axial clearance adjustments. They can meet usage conditions without preload between one or two nuts, eliminating axial gaps to ensure appropriate rigidity. Cycle Method TBI MOTION's own internal and external circulation and end-cap circulation cover patented cycle numbers to meet customer needs. Excellent Durability The cumulative production technology of TBI ball screws, along with the use of materials through strict heat treatment and processing techniques, can provide durable products.

Features of Ball Splines High Load Capacity Ball splines utilize precision-ground rolling surfaces with a 40° Gothic arch contact angle, resulting in a significant load capacity for both radial loads and rated torque due to the increased contact angle. Zero Play in Rotational Direction The spline shaft and spline outer cylinder consist of a contact angle of 40° with two-row and four-row ball arrangements. By properly adjusting the pre-load, the play in the rotational direction can be reduced to zero, enhancing rigidity. High Performance The ball in the raceway is composed of unique contact points, providing high rigidity along with high performance and low friction for energy savings. High Rigidity The raceway has a large contact angle (40°), which allows for high rigidity. Additionally, by applying appropriate pre-load, excellent torque rigidity and moment rigidity can be achieved. Ease of Assembly Thanks to a special design, the balls do not fall out even when the spline outer cylinder is removed from the spline shaft. This makes assembly, maintenance, and inspection easier.
