Overview
Where Does the Enduro 608 Sealed Bearing Fit on Your Bike?
The Enduro 608 Sealed Cartridge Bearing fits the 8mm x 22mm x 7mm profile found in a wide variety of cycling components, from suspension pivots and jockey wheels to pedal axles and small-bore hub applications. Mobilux NGLI 2 synthetic grease fills 90% of the interior, providing reliable lubrication that holds up through extended service. Dual-lip labyrinth seals block contamination without creating excessive drag, keeping the bearing rolling smoothly with minimal resistance over time.
The 608 is one of the most commonly used bearing sizes in cycling, found across rear derailleur cages, suspension linkage pivots, and a number of aftermarket pedal and wheel hub designs. Enduro's tight manufacturing tolerances deliver a precise fit that resists creaking and shifting under load. For shop technicians and home mechanics who do their own wrenching, having 608 sealed cartridge bearings on the shelf is good practice for handling the most frequent small-bearing replacements without a parts delay.

Good questions
Get to know Enduro

There's more to Enduro than this one product. Our Enduro page has the full Enduro lineup we carry and more about the brand.
Visit the Enduro page →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.
