HOWO Drive Axle Roller Bushing WG9761450121
Specially engineered for HOWO heavy-duty trucks, the WG9761450121 roller bushing serves as a critical component within the drive axle system. This precision component ensures smooth rotational movement while withstanding extreme pressures and vibrations commonly encountered in commercial truck operations. Manufactured to exact HOWO specifications, the roller bushing WG9761450121 provides optimal load distribution across the axle assembly.
Design and Functionality
Constructed from high-grade sintered bronze alloy, the roller bushing features a unique micro-porous structure that naturally retains lubricants. This self-lubricating design significantly reduces friction coefficients even under heavy payload conditions. The component’s cylindrical geometry precisely matches drive axle housing dimensions, eliminating play and preventing premature component wear.
Performance Advantages
- Increased service life compared to standard bushings (3x longer under stress testing)
- Operational temperature range: -40¡ãC to +220¡ãC
- Vibration dampening properties reduce harmonic resonance
- Compatible with all standard commercial lubricants
- Seamless integration with HOWO Genuine Drive Axle Assemblies

Application Scenarios
This roller bushing performs optimally in multiple operational environments including long-haul freight transport, construction material delivery, mining operations, and refrigerated logistics. The WG9761450121 component proves particularly effective in vehicles carrying oversized payloads where axle stress is dramatically increased. Operators report noticeable reductions in cabin vibration and drivetrain noise after installing genuine HOWO roller bushing components.
Maintenance Recommendations
For maximum durability, conduct bushing inspections during every major service interval (typically 50,000 km). Ensure proper lubrication channel clearance and check for abnormal wear patterns. Use only approved greases that match the original viscosity specifications. Avoid pressure washing that could force contaminants into the porous metal structure. Remember that the WG9761450121 roller bushing is designed for single installation – never attempt to reuse removed components.
Compatibility Information
Compatible with HOWO A7, HOWO T7G, and HOWO T5G series trucks manufactured between 2018-2024. May require adapter sleeves when retrofitting older axle assemblies. Always verify drive axle serial numbers before installation. This genuine WG9761450121 part supersedes earlier bushing models including WG9761450119 and WG9761450120.
Quality Assurance
Each roller bushing undergoes coordinate-measuring machine (CMM) verification and surface roughness testing before packaging. Batch-level traceability ensures full manufacturing history documentation. The product ships with protective caps to prevent transit damage to precisely machined surfaces. Genuine HOWO packaging includes holographic authentication labels for counterfeit protection.
