SKF offers new Lincoln 5900 PowerLock coupler
SKF today announced the introduction of its Lincoln 5900 PowerLock grease coupler.

Developed to optimize lubricant delivery, this coupler is suitable for agriculture, construction and general industry, as well as vehicle service applications.

The easy-to-use PowerLock coupler is lever activated for quick attachment and release. Its reverse-jaw design holds the fitting securely to the seat for less grease bypass and lower lubricant costs while enabling single-handed operation. The coupler’s durable, all-steel construction provides long service life.

The PowerLock coupler features a comfortable, ergonomic design. Its flexible rubber sleeve offsets pressure applied to the lever and protects the hose from unnecessary wear.
