High Performance Rear Wheel Bearing / Axle Bearing Complete Kit for Yamaha Raptor YFM700R & YFZ 450R
Excessive play in the rear axle, grinding noises, or premature bearing wear are common issues in high-performance ATVs exposed to mud, water, sand, and continuous load. This reinforced rear wheel bearing / axle bearing complete kit has been specifically developed as an upgrade solution for the Yamaha Raptor YFM700R and Yamaha YFZ 450R models. It replaces the factory-installed standard bearings with a strengthened dual-bearing configuration designed to increase load capacity and durability under demanding riding conditions.
Upgraded Dual-Bearing Construction for Increased Load Capacity
Unlike conventional OEM standard bearings, this All Balls upgrade kit utilizes a reinforced dual-bearing design. The result is up to 30% higher load capacity compared to standard configurations. For riders who frequently operate their ATV under heavy acceleration, aggressive cornering, or off-road competition use, this design significantly improves structural stability at the rear hub assembly.
-
Dual-bearing technology: Improved load distribution across the axle
-
Up to 30% higher load rating: Enhanced resistance to mechanical stress
-
Precision-manufactured bearings: Reduced rolling resistance and smooth rotation
-
High-speed capability: Designed for extreme rotational speeds
-
High-temperature resistance: Stable performance under thermal stress
Advanced Sealing System for Harsh Off-Road Conditions
Rear axle bearings in ATVs are constantly exposed to water crossings, mud, dust, winter road salt, and sand. Standard sealing systems often allow contaminants to penetrate the bearing cavity, leading to corrosion, lubrication loss, and premature failure. This High Performance wheel bearing kit addresses these issues with a multi-stage sealing concept.
Double-Lip Bearing Seals
The integrated double-lip seals provide superior protection compared to single-lip OEM versions. This construction effectively minimizes the intrusion of:
- Water during wet or muddy riding conditions
- Fine dust and sand particles in dry terrain
- Salt exposure during winter operation
- Debris under high-speed off-road use
Additionally, the double-lip design helps retain grease inside the bearing, even under extreme operating conditions.
TC Type Nitrile Elastomer Oil Seals
The included TC-type oil seals are manufactured from high-quality nitrile elastomer and specifically engineered for harsh environments. The rubber-coated outer diameter ensures a secure and tight fit within the hub housing. An integrated steel garter spring maintains constant radial pressure on the axle shaft, which significantly extends service life compared to conventional original bearings.
OEM-Compatible Fitment with Reinforced Durability
This rear wheel bearing and axle bearing kit matches the original dimensions for the specified Yamaha models. Installation is performed in the same way as the original components without structural modifications. The design focus is on increased durability and resistance while maintaining precise OEM fitment.
Installation tools are not included in the scope of delivery.

Application-Specific Performance Benefits
If your ATV rear axle shows lateral movement, produces noise during rotation, or if moisture contamination has reduced bearing lifespan, this upgrade kit provides a technically optimized solution. The reinforced load structure increases bearing capacity, while the advanced sealing system protects against environmental exposure. This makes the kit particularly suitable for performance-oriented riders, competitive use, and heavy-duty off-road applications where standard bearings typically reach their limits prematurely.
By combining OEM-compatible dimensions with enhanced structural and sealing properties, this High Performance wheel bearing kit delivers a durable, precision-engineered replacement solution for Yamaha Raptor YFM700R and YFZ 450R rear axle assemblies.
