Rear Wheel Hub for 30HB Forklift Steering Axle — Complete Hub Assembly

This rear wheel hub assembly is precision-manufactured for the 30HB-type steering axle used on 2.5-3.5 ton diesel forklifts from Heli, Hangcha, Lonking, and other Chinese manufacturers. The rear wheel hub is a critical dual-function component: it mounts to the steering knuckle via opposed tapered roller bearings to support the full rear weight of the forklift plus dynamic load transfer during braking and cornering, and through the knuckle it transmits hydraulic steering cylinder forces to the wheel to enable the rear-wheel steering articulation that gives counterbalance forklifts their characteristic tight-radius maneuverability. A worn hub with bearing race spalling, an elongated or cracked mounting flange, or stripped wheel stud threads produces steering wander, rear wheel wobble visible at travel speed, uneven tire wear, and if left unresolved, bearing seizure or complete wheel separation from the vehicle. Timely hub replacement restores steering precision, eliminates vibration, and ensures safe operation.

Manufactured from high-grade cast steel or ductile iron with optimized wall thickness and internal rib reinforcement at the bearing seat areas where cyclic stress concentrations are highest. Inner and outer tapered roller bearing races are precision press-fitted into line-bored housings with the correct interference fit and axial clearance for proper bearing preload — a critical specification that directly affects steering feel, tire life, and bearing durability. Wheel studs are hydraulically press-fitted from the rear with serrated shanks that mechanically lock into the hub flange to prevent rotation during lug-nut tightening. The hub exterior is shot-blasted and finished with anti-corrosion primer and paint designed for outdoor forklift operating environments.

Direct fit for Heli CPCD25-CPCD35 and A30/A35 series, Hangcha CPCD25-CPCD35, Lonking LG25D-LG35D, and other 2.5-3.5 ton forklifts with 30HB-type rear steering axles. Always replace bearings, seals, and spindle nut cotter pins when installing a new hub. Verify stud count, PCD, and bearing dimensions before ordering.
