Lincoln SL-6 Single-Line Grease Injector

Nov. 14, 2020
The latest addition to SKF’s single-line lubricant injector range contributes to increased productivity in tough applications.

The SKF Lincoln SL-6 injector has been designed for ease of use and maintenance in mind, with outstanding leak protection and service life, even with harsh EP (extreme pressure) greases. The SL-6 can easily be retrofitted to existing single-line pump systems.


Innovations in the SL-6 are focused on supporting the harsh environments for which it is designed, including in dump trucks, excavators, and other mining and construction equipment. Quick maintenance features include a highly visible red indicator pin, an adjusting screw requiring only basic tools, and a hex-shaped body that maximizes working space, making it easy to handle and work with.


For optimally effective lubrication, its vent speed is faster than that of any competitor. This is aided by a daisy-chain effect: as soon as each injector finishes venting, it helps the next one to complete its cycle by consuming grease from the mainline. Improved sealing reduces the risk of lubricant bypass. In the unlikely event of a failure, the injector’s closed structure channels bypass lubricant to the bearing. Repair is then possible by simply replacing two components.
