Designed to meet or exceed OEM specifications, each kit includes premium deep groove ball bearings and Nitrile Butadiene Rubber (NBR) double-lip oil seals—manufactured to strict dimensional tolerances to ensure proper hub alignment and smooth front wheel rotation.

Unlike generic aftermarket replacements, Factory Links bearings are packed with a heavy-duty marine-grade grease and a specialized thickener blend that improves water resistance and corrosion protection in harsh riding conditions.

Every kit includes all components required for a complete front wheel hub rebuild—helping eliminate play, restore smooth rotation, and extend service life in mud, water, sand, and extreme off-road environments.

Technical Details

HEAVY-DUTY BALL BEARINGS

Factory Links OEM Series front wheel bearings are manufactured to DINP6 – ABEC3 standards and developed specifically for off-road motorcycle applications.

Precision-ground races for smooth and consistent wheel rotation
Optimized internal clearances to handle impact loads
High-grade bearing steel for extended durability

Front wheel bearings must withstand braking forces, steering loads, and repeated impacts—our bearings are engineered accordingly.

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 grease featuring:

Enhanced moisture resistance
Superior rust and corrosion protection
Extended lubrication intervals

This specialized grease blend helps reduce premature wear caused by frequent washdowns and wet riding conditions.

FAQs

Q: How do I know if my front wheel bearings are worn?
A: Common signs include side-to-side wheel play, rough rotation, grinding noise while rolling, or visible contamination during inspection.

Q: Does this kit include seals?
A: Yes. All OEM Series Front Wheel Bearing Kits include both bearings and oil seals required for a complete hub service.

Q: Is this kit suitable for motocross and enduro use?
A: Yes. These kits are designed specifically for off-road applications where durability and contamination protection are critical.

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.
