Miniature Linear Way Series - Standard and Wide, Carbon Steel and Stainless Steel
The LWL Series offered by AST Bearings 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 standard products are made of stainless steel, and a wide range of variations in shapes and sizes are available for selection suitable for each application. The LWL Series is widely used in such fields as medical equipment, semiconductor manufacturing equipment, and liquid crystal related equipment, where its excellent performance has been proved.

Miniature Size
The smallest size models, LWL 2 (track rail width: 2 mm) and LWL-F 4 (wide rail type) have been recently added to the series. These models will contribute to further reduction in size and weight and improvement in performance of equipment.
High Accuracy Achieved By Eliminating the Number Of Potential Errors
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.
Stainless Steel Series with Excellent Corrosion Resistance
Stainless steel LWL Series, which is more resistant to corrosion than the high carbon steel models, is most suitable for applications in clean rooms and in places where the use of rust preventive oil must be limited or avoided because any oily content is inimical to the environment. It is most suitable for machines and equipment used in clean rooms and environments such as: medical equipment, disk read devices, and semiconductor manufacturing equipment. Product specifications most suitable for the needs in diversified special environment applications can be provided by combining various special specifications.
Furthermore, by replacing the standard synthetic resin end plates with stainless steel end plates, the LWL Series can be used in a vacuum environment and its heat resistance can be improved as well. When ordering, indicate this specification in combination with the specification of "with no end seals" (supplemental code "/N") or the specification of "with seals for special environment" (supplemental code "/RE").
Ball Retained Type Realized In Miniature Series
The slide unit of ball retained type incorporates ball retaining bands, which prevent steel balls from dropping when the slide unit is separated from the track rail. So mounting on machines and equipment can be made easily.
Numerous Variations
Two types with different section shapes, the standard type and the wide rail type, are available. In each of these types, three types with different lengths are also provided. The wide rail type can support a large moment load acting around the axial direction, and is suitable for single row rail arrangement. In addition to the standard specification track rail which is fixed by inserting bolts downward in the mounting holes, the tapped rail specification track rail that has tapped screw holes is available, so an optimum mounting direction can be selected, giving more freedom in machine design.
