Couplemate manufacturers market and distribute a comprehensive range of high-quality running gear, including axles, brakes and suspension products.

Bearing dollies are a fantastic tool for mechanics. The specific tool for the job saves time and blood.

Bearing failure is often caused by a lack of maintenance or checking bearings before travelling long distances. Even the best 2t bearings need checking after long rests between trips.

The consequence of not checking your bearings is a costly disaster. Sorry to be blunt.

Important information for Marine Bearing Seals.

Marine seals are designed to rotate inside their metal retaining ring.

Friction can create heat up to 100 degrees C.

You must liberally grease this seal around the outside ring of a marine seal. The seal is then placed onto the axle, not into the hub.

A dry marine seal causes excess heat.

When replacing bearings, it is wise to remove the old bearing cups. Cups and races are subject to wear and tear. Carbon black in your grease or black grease is a sign of bearing wear. Immediately replace bearing cups and races.

Low-quality wheel bearings have inferior coatings and low tolerances.

Use high-temperature bearing grease at high speeds.
