Slide guideway ER series

miniatureprecisionstainless steel

The 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 cage 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. 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 Vshaped grooves machined on the outer rail and the inner block to allow the system to slide. It is an ultrathin, 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. Reduced Design and Assembly Costs It provides a highly accurate linear guide system with lower design cost and fewer assembly manhours 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 coeffi cient. This slide unit maintains stable performance over a long period of time.
