Linear way bearings incorporate several rows of recirculating balls or rollers for low friction and precise linear motion and have a rectangular shaped track. Made of stainless steel, and with a wide range of variations in shapes and sizes, the LWL Series offered by AST Bearings are widely used in such fields as medical equipment, semiconductor manufacturing equipment, and liquid crystal related equipment.
The LWL Series is a miniature type linear motion rolling guide, incorporating two rows of steel balls arranged in four-point contact with the raceways. Owning to its simple design, it provides stable accuracy and rigidity even in operations under fluctuating loads with changing direction and magnitude or complex loads.
The simple two-row, four-point contact design minimizes the number of potential errors in manufacturing and measurement, so the highest level of dimensional accuracy between rows can be achieved. Interchangeable specification products of high-interchangeability level can be manufactured benefiting from this feature by rigorous control of the dimensional accuracy of individual slide units and track rails.
