Our CLube technology maintains the lubrication performance for an extended period of time, reducing lubrication schedules and the time it takes to manage them.

A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Small Rolling Frictional Resistance Incorporating a ball with high accuracy into the precisely polished external cylinder results in small rolling frictional resistance and extremely smooth rolling motion together with reciprocal motion. Low Inertia Since the retainer has high rigidity and is lightweight, it has low motion inertia, making it suitable for rolling motion and reciprocal motion in highspeed operations. A Variety of Models Standard and heavy load models are available, each with different load ratings, and each offered with or without seals. It is easy to choose the right product based on the specifications of your machine or device.

A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Super Precision After the raceway surface of the external cylinder and shaft are heat treated, they receive an ultraprecision finish and are set to zero or a slight preload state by incorporating high precision steel balls. This provides extremely high accuracy in both rotary and linear motion. Super Small Size Tiny balls incorporated in a thin external cylinder result in a very small diameter and small sectional height. Since each component is precisely ground and adjusted to ideal preload conditions, extremely smooth and stable operation with low frictional resistance over a long period of time is possible.

Interchange specifications are available. Since the external cylinder and spline shaft dimensions are separate, each can be individually added or exchanged. Two external cylinder shapes are available standard (cylindrical) and flange. External Cylinder Length Both the standard type and flange type offer two external cylinder length options, standard and highrigidity long. They can be used for a wide range of applications offering greater design flexibility. Solid Shaft and Hollow Shaft The spline shaft is available in either a solid shaft or hollow shaft, which can be selected according to the application. Stainless Steel A stainless steel spline shaft can be selected as an option. They are best suited for applications where rust prevention oil cannot be used, such as in a cleanroom environment.
