Precision Linear Pack Model ER Model ER
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 straight 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.
Basic load rating (kN): Basic dynamic load rating 54.9 to 215 / Basic static load rating 72.5 to 315
