FAQ

What components on my bike commonly use a 608 bearing?

The 608 appears in rear derailleur jockey wheel cages, suspension linkage pivots, some pedal axle designs, and select hub applications. It is one of the most universally used bearing sizes across all bike categories.

How do I know when my 608 jockey wheel bearing needs replacement?

Listen for roughness or feel for drag when spinning the jockey wheel by hand. Visible side-to-side play or gritty rotation are both signs the bearing is due for replacement. Swapping jockey wheel bearings is one of the most affordable drivetrain service items you can do.

Can I use this bearing in a non-cycling application?

The 608 is a universal bearing size used across many industries. Enduro bikes them specifically for cycling applications, but the dimensions and quality make them suitable for a wide range of small-machine and hobbyist applications as well.

Best For

Cyclists doing drivetrain maintenance who want a reliable replacement for worn jockey wheel bearings, and home mechanics who service suspension pivots or pedals that use the 8x22x7mm form factor. Keeping a few 608s on the shelf means you are always one step ahead on routine service.
