SKF SLC Series Metering Device

For use in single-line lubrication systems

The SKF Lincoln SLC metering device is designed for use in high-pressure single-line lubrication systems and features a modular design. Also, delivery volume can be adjusted via metering screws, helping to ensure each lubrication point receives the required amount of lubricant. Featuring a spring-reset control piston, the metering device has a high venting capability compatible with greases up to NLGI 2. The SLC offers easy configuration to meet your needs, including different output quantity, fitting and adjustment options. 

With the most compact construction in its class, the SLC is suitable for many applications in renewable energy, construction, mining as well as in heavy industry.
