Metering valves cut lubricant consumption by 25 per cent on linear guidance systems

By incorporating special lubricant metering discs on its range of linear recirculating roller bearings and guideway assemblies, Schaeffler has reduced lubricant consumption by more than 25 per cent compared to conventional designs.

A range of linear recirculating roller bearings and guidance systems are now available with special lubricant metering valves, which provide precise doses of lubricant to the linear guides, reducing lubricant consumption by more than 25 per cent compared to standard designs, reducing maintenance and servicing costs and preserving resources for the customer.

Schaeffler’s RUE-E range of roller monorail guidance systems can now be fitted with special lubricant metering valves to ensure that the lubricant is precisely metered under all operating conditions, regardless of the guide’s mounting position. This is made possible because of several key design factors.

First, Schaeffler uses a patented injection moulding technology to produce the saddle plate, which, combined with the various connection options for relubrication at the front, rear and side of the carriage end, and the special design of the end pieces – the lubricant is directed precisely at the rolling elements. This not only minimises relubrication quantities, but also improves the reliability of the guide and is kinder to the environment.
