Caps & Bearing Buddies

Holden, Ford, Parallel, 2t Al-ko, 2t Dexter and Simplicity Dust Caps
The dust cap is also known as a grease cap, which indicates that grease is held in the cap. While this is true, grease caps fill with excess grease, and the more common term is dust cap.

Caps for caravans and trailers are a pressed metal or compressed fit instead of a machine fit (Bearing Buddy).

Pressed metal caps are slightly larger than the hub. The circumference is squeezed during insertion. The squeezing or compression of the circumference holds the cap into place.

Bearing failure causes the hub bearing surface to scour on the axle. As a result, the outer hub journal becomes oversized, damaged, and discoloured.

Couplemate has chosen a galvanised grease cap to help stop the effects of corrosion that will occur over time.

Galvanised grease caps are available for Ford, Holden, parallel and 2t bearing kits.
