Precision Linear Pack

Model ER is a slide unit using a stainless steel plate that is precision formed, heat-treated, and then ground. It has a structure where balls roll between the V-shaped grooves machined on the outer rail and the inner block to allow the system to slide. It is an ultra-thin, Lightweight unit in which the balls circulate in a ball case incorporated in the inner block to perform infinite linear motion.
This model is used in extensive applications such as magnetic disc devices, electronic equipment, semiconductor manufacturing equipment, medical equipment, measuring equipment, plotting machines, and photocopiers.

Reduced Design and Assembly Costs

It provides a highly accurate linear guide system with lower design cost and faster assembly than the conventional miniature ball bearings used in precision machines and other equipment.

Maintains Long-Term Stability

It is a ball-circulating type slide unit with an extremely small friction coefficient. This slide unit maintains stable performance over a long period of time.

Lightweight and Compact with High-Speed Response

The outer rail and the inner block are composed of very thin stainless steel plates. Since the linear pack is light, it has a small inertial moment and demonstrates superb highspeed response.
