Introduction

The 30311 (outer) and 30314 (inner) tapered roller bearings are dedicated front wheel hub spare parts specially engineered for FAW series heavy-duty trucks, including FAW J6, JH6 and other mainstream FAW axle models. As core chassis components, they work in pairs to undertake the radial and axial loads of the front wheel during vehicle driving, steering and braking. Adopting standard tapered roller bearing structure, these two models form a complete front wheel bearing assembly, featuring precise dimensional matching, stable rotation and strong impact resistance. Fully compliant with OEM specifications, they serve as ideal replacement parts for FAW truck front wheel hub maintenance and overhaul, perfectly adapting to the harsh working conditions of heavy-load transportation, long-distance driving and complex road conditions.

Key Features

✅️Perfect FAW Original Matching:

30311 outer bearing and 30314 inner bearing are tailor-made for FAW series heavy trucks, perfectly matching FAW 300 axle, J6, JH6 and other mainstream models. The size and installation interface are completely consistent with OEM standards, realizing plug-and-play installation without modification, which greatly improves maintenance efficiency and avoids assembly deviation caused by mismatched parts.

✅️Superior Heavy-load & Impact Resistance:

The 30314 inner bearing boasts a high dynamic load rating of 271kN and static load rating of 260kN, while the 30311 outer bearing supports stable load-bearing operation. The tapered roller structure can evenly disperse radial and axial comprehensive loads, effectively coping with heavy cargo loads, bumpy roads and sudden braking impact during truck operation, ensuring stable wheel support without deformation or damage.

✅️High-precision & Stable Rotation Performance:

Manufactured with precision grinding process and strict tolerance control, the bearings feature smooth roller operation, low friction coefficient and low noise. The optimized internal structure design ensures uniform stress distribution, effectively reducing wheel rotation resistance, alleviating tire wear and steering jitter, and improving driving smoothness and handling accuracy of FAW trucks.

✅️Excellent Durability & Long Service Life:

Made of high-strength bearing steel with integral heat treatment and anti-fatigue processing, the products have high hardness, wear resistance and oxidation resistance. They maintain stable performance under high-speed rotation, variable load and long-term continuous operation, effectively delaying wear and aging, reducing frequent replacement frequency, and lowering the overall vehicle maintenance cost.

✅️Strict Quality Control & High Reliability:

All bearings undergo strict quality inspection including load testing, speed testing and durability aging testing. With stable limit speed performance, they can adapt to the long-distance and high-intensity operation mode of heavy trucks. The sealed and dust-proof optimized structure effectively isolates dust, sediment and muddy water, preventing internal grease failure and bearing damage, and adapting to various complex working environments.

✅️Cost-effective OEM Replacement Solution:

As professional special spare parts for FAW trucks, the products have stable quality comparable to original parts, with more competitive prices. They support batch wholesale and customized packaging, providing high-cost-performance maintenance and replacement solutions for fleet companies, repair factories and parts distributors, with sufficient stock and fast delivery.
