Introduction

This matched pair tapered roller bearings (30619 inner bearing + 30621 outer bearing) are professional aftermarket replacement parts specially designed for FAW New Dawei, FAW J5P, FAW J6 heavy-duty truck rear wheel hubs. As core rotating components of the rear axle, they bear huge radial and axial combined loads during heavy-load transportation, supporting stable wheel rotation. Manufactured strictly per OEM dimensional standards, the inner and outer bearings perfectly match the original hub assembly, realizing direct installation without modification. They effectively solve common faults like bearing overheating, abnormal wheel noise, wheel shake, roller peeling and hub damage, widely used for truck repair shops, fleet maintenance and bulk spare parts wholesale.

Key Features

✅️Exact OEM Matching Pair Set

Complete matching kit of inner bearing 30619 and outer bearing 30621, fully compatible with FAW New Dawei, J5P, J6 rear axles. Consistent size, taper angle and mounting clearance with original bearings, no assembly deviation after replacement.

✅️High-Strength GCr15 Bearing Steel Material

Adopts high-carbon chromium alloy steel, through overall quenching and tempering treatment, high hardness, strong wear resistance and impact resistance, coping with heavy cargo and bumpy road conditions.

✅️Dual Load-Bearing Tapered Roller Structure

Single-row tapered roller design can bear both radial and axial loads at the same time, evenly disperse axle pressure, reduce roller abrasion, avoid wheel offset during braking and turning.

✅️Low Noise & Stable Rotation Performance

Precision grinding on roller and raceway surface, smooth operation, effectively eliminate abnormal roaring noise during driving, improve driving comfort and safety.

✅️Strong Dust & Grease Retention Performance

Precise fit between inner cone and outer cup, cooperate with hub oil seal to lock lubricating grease inside, block dust, muddy water and gravel intrusion, reduce bearing corrosion failure.

✅️Strict Factory Full Inspection

Each bearing undergoes hardness test, clearance detection, rotation noise test and load pressure test before delivery, stable quality and long service life, cut frequent replacement cost for fleets.

✅️Cost-Effective Complete Kit Supply

Sold as matched inner & outer bearing set, one-stop purchase to save procurement time, stable stock for bulk wholesale orders, high cost performance to replace damaged original hub bearings.
