Product Details

Overview & Technology

Wheels Manufacturing SB-6802 sealed cartridge bearings are precision steel bearings built for day-in, day-out drivetrain and wheel duties. These 6802-class bearings measure 15 x 24 x 5 mm, use hardened steel races and steel balls, and arrive as fully sealed cartridges to keep grit and moisture out while holding grease in. The bearings are rated ABEC 3 — a practical, real-world tolerance grade that balances smooth rotation and durability for cycling applications. Because they're sealed and pre-greased, installation is quick and maintenance intervals are extended, making them a dependable choice for jockey wheels, accessory hubs, pivots and other small rotating parts on mountain bikes.

Key Features & Benefits

Materials & construction: CNC-quality steel races and steel balls provide robust load capacity and resistance to wear. The integrated rubber seals prevent contamination and retain grease under rough, muddy conditions. • Sealed cartridge design—ready to install and simple to replace. • ABEC 3 tolerance—reliable, low-friction performance optimized for cycling loads and speeds. • Pre-greased steel bearings—long service life in real-world trail conditions.

Fit, Dimensions & Compatibility

These SB-6802 bearings are sized 15 x 24 x 5 mm (inner diameter x outer diameter x width) and sold in a bag of two. The compact 6802 size is commonly used in derailleur jockey wheels, some small hub endcaps and accessory pivots. Wheels Manufacturing also offers a larger SB-6805 (25 x 37 x 7 mm) if your application needs a different diameter or width. Before ordering, confirm the inner diameter (15mm) and outer diameter (24mm) match the part you're replacing. The sealed cartridge design may be press-fit or drop-in depending on the application — some housings require a light press or a bearing driver to seat cleanly. Shipping dimensions and weight are minimal (3" x 3" x 0.5", 0.05 lb), so replacements arrive quickly and are easy to stock in a workshop kit.

Who These Bearings Are For

These sealed steel cartridge bearings are ideal for mountain bikers, mechanics and home wrenchers who want a tough, low-maintenance replacement for small rotating components. They're perfect when you need a cost-effective steel bearing that stands up to mud, grit and repeated impacts on the trail. If you race enduro or need maximum speed gains, you might choose ceramic or higher ABEC-rated bearings for very specific applications — but for most mountain-bike jockey wheels, small hubs and pivots, the SB-6802 delivers the best balance of reliability, cost and durability.

Frequently Asked Questions

What does ABEC 3 mean and does it matter for bikes?

ABEC 3 indicates the bearing's manufacturing tolerance and roundness. For cycling components like jockey wheels and small hubs, ABEC 3 offers a practical balance of smoothness, durability and cost — higher ABEC numbers give tighter tolerances but deliver minimal real-world advantage for most mountain-bike uses.

Can I use these bearings in my derailleur jockey wheels?

Yes — the 15 x 24 x 5 mm size is a common fit for many jockey wheels. Always confirm the diameter and width of the bearing in your pulleys before ordering. If your pulley uses a pressed-in bearing, you may need a small press or bearing driver for clean installation.

Are these bearings serviceable or disposable?

The SB-6802 is a sealed, pre-greased cartridge bearing designed for low maintenance. While you can replace them when wear occurs, they are not intended for easy re-greasing — replacement is typically the simplest option when performance drops or seals are damaged.

How do sealed steel bearings compare to ceramic options?

Steel bearings are tougher, less brittle and far more cost-effective than ceramic bearings. Ceramic bearings can offer marginally lower rolling resistance and weight savings, but for rugged mountain-bike use where impacts and contamination are common, sealed steel bearings are usually the better, longer-lasting choice.

Do these bearings come as singles or pairs?

SB-6802 bearings are sold in a bag of 2, which is convenient for replacing a pair of jockey wheels or other paired components. Wheels Manufacturing also offers different sizes (for example SB-6805) sold in the same bag-of-two format.

Buying Guide

Choose the right bearing by matching inner and outer diameters and width to the part you're replacing. For most mountain-bike applications, sealed steel cartridge bearings offer the best combination of reliability, impact resistance and affordability. Consider the operating environment: sealed bearings are preferable for wet, muddy or dusty rides because they keep contaminants out. If you need marginal speed gains for a low-contamination application, explore ceramic options, but expect higher cost and potentially lower impact resistance.
