New linear bearings for shafts ensure precision and rigidity

Bearings made of iglidur W360 high-performance polymer ensure precise and easy movements in linear technology. Consisting of an aluminium housing and a thin polymer liner, which ensure smooth and quiet operation combined with high rigidity, these bearings do not need external lubrication.

Linear guides are used wherever goods or objects need to be moved from A to B, or equipment or machines need to be adjusted. Precision often plays a major role for users, for example in microscope tables or in X-ray equipment. In order to meet the requirements of such applications, igus has developed the linear plain bearing series W360CM, ensuring the highest precision and rigidity in drylin R shaft guides. The long-lasting sliding elements of the bearings are characterised by a thin wall thickness and high strength. They are produced cost-effectively in injection moulding from the high-performance polymer iglidur W360. The material enables very quiet and smooth operation. The operating temperature range is between 0-50 degrees Celsius. Due to the thin wall thickness and the higher material strength, the linear bearings ensure a low bearing clearance at the operating point due to reduced elasticity. The new bearings – like all plain and linear bearings from igus – are free of lubrication and therefore free of contamination and maintenance.

Flexible mounting combined with a simple design

The W360CM linear bearings can be easily mounted in all drylin housings as well as in all standard housings for linear ball bushings.  This means that ball-based solutions can be converted 1:1 without a construction wall using the maintenance-free solution. The design of the new linear bearings is simple: the liners are pressed into the housing until a pre-loaded snap hook is inserted into a groove. Thus, the films are secured against displacement even under high loads and temperatures. The new drylin R series was also able to convince in tests in the in-house laboratory at igus. Gauge measurements to check bearing clearance and precision showed that the W360CM series bearings performed far better than coated linear bearings.
