Factory Links OEM Series® Complete Wheel Bearing Kits provide a convenient solution for servicing both wheel hubs at the same time – combining our front and rear wheel bearing kits into one package for simplified maintenance. Image of Front & Rear Wheel hubs with Factory Links OEM Series bearings.

Designed to meet or exceed OEM specifications, these kits deliver OEM-level performance and durability at a significantly lower cost than purchasing equivalent components individually through the dealer. Each kit includes deep groove ball bearings and Nitrile Butadiene Rubber (NBR) double-lip oil seals manufactured to strict dimensional tolerances to ensure proper axle alignment, smooth wheel rotation, and long-term reliability.

Front wheel bearings must withstand braking forces, steering loads, and repeated impacts from rough terrain. Rear wheel bearings operate under continuous drivetrain torque from the chain and sprocket assembly while supporting greater sustained load from acceleration and rider weight. Factory Links bearings are engineered specifically to handle these different load conditions while maintaining smooth rotation and long service intervals.

Each kit contains everything required for a complete front and rear wheel hub rebuild, helping eliminate wheel play, restore smooth rotation, and extend service life in mud, water, sand, and extreme off-road riding conditions.

For exact compatibility, refer to the Fitment tab or use the Year/Make/Model search tool.

Technical Details

HEAVY-DUTY BALL BEARINGS

Factory Links wheel bearings are engineered specifically for off-road motorcycle applications, where exposure to water, mud, sand, and repeated washdowns is common. Cutaway view of Factory Links OEM Series front wheel bearing showing internal ball elements and seal design.

Unlike many generic aftermarket bearings that rely on standard industrial 2RS seals – designed primarily for low rotational torque in controlled environments – Factory Links bearings feature sealing and lubrication systems optimized to provide greater resistance to water intrusion and contamination in harsh riding conditions.

• Precision-manufactured components for smooth and consistent wheel rotation
• Optimized internal clearances to accommodate braking forces and drivetrain loads
• High-grade bearing steel for long-term durability
• Engineered to withstand impacts, radial loads, and sustained torque

Front and rear hubs experience different load conditions – from braking forces and steering loads at the front to drivetrain torque at the rear. Factory Links bearings are engineered to perform reliably in both environments, helping maintain lubrication, reduce corrosion risk, and extend bearing service life in demanding off-road conditions.

This off-road focused design philosophy is why Factory Links components are trusted by manufacturer's like SHERCO, and professional race teams competing in MXGP, WorldSX, GNCC, and the Hard Enduro World Championship.

OFF-ROAD SPECIFIC OIL SEALS

Each kit includes premium NBR double-lip oil seals designed to:

Prevent intrusion of water, mud, and dust
Retain grease under high rotational speed
Maintain sealing integrity in aggressive riding conditions

These seals are purpose-built for off-road motorcycles – not industrial substitutes.

MARINE-GRADE GREASE FILL

All Factory Links OEM Series bearings are pre-packed with a high-performance marine-grade grease featuring:

Enhanced moisture resistance
Superior rust and corrosion protection
Improved lubrication stability in harsh environments
Extended service intervals

This specialized grease blend helps protect bearings from premature wear caused by water crossings, mud, sand, and repeated bike washdowns.

FAQ's

Q: How do I know if my wheel bearings need replacement?
A: Common signs include wheel play at the axle, rough rotation, grinding noise while spinning the wheel, or visible contamination during inspection.

Q: Why would I choose this kit instead of buying front and rear separately?
A: Wheel bearings are exposed to the same riding conditions and maintenance cycles. When contamination or wear begins affecting one hub, the other is often close behind. Servicing both wheels at the same time helps restore smooth rotation, eliminate play, and prevent future downtime – while ensuring consistent performance across the entire chassis.

Q: What is included in this kit?
A: This kit combines both the Factory Links Front Wheel Bearing Kit and Rear Wheel Bearing Kit, providing bearings and oil seals required to service both wheel hubs.

Q: What makes Factory Links wheel bearings different from generic aftermarket bearings?
A: Many aftermarket wheel bearing kits use standard industrial 2RS-type bearings, which are designed for low rotational resistance in controlled environments. Off-road motorcycles operate in much harsher conditions, with constant exposure to water, mud, sand, and frequent washing.

Factory Links wheel bearings are engineered specifically for off-road motorcycle applications, with optimized sealing systems, marine-grade grease, and internal tolerances designed to better resist contamination and maintain lubrication in extreme riding environments.

Q: Do I need special tools to install wheel bearings?
A: Proper installation typically requires basic hand tools and the correct bearing driver or press tools to avoid damaging the hub or bearing seats. For best results, install bearings squarely, avoid force through rolling elements, and verify seal orientation during assembly.
