Specifications & Features
Product Description
1. Product Material & Production Craft
1.1 Bearing Base Material
The whole wheel hub bearing unit adopts high-quality GCr15 chrome bearing steel as raw material. After integral forging, rough turning and finish turning, the hub blank gets uniform internal metal texture, effectively avoiding cracking and deformation under heavy load. The raceway surface undergoes superfinishing treatment, achieving ultra-smooth finish to reduce friction and running noise.
1.2 Heat Treatment Process
Complete overall quenching and low-temperature tempering process is applied. The bearing raceway and rolling elements reach stable high hardness, with strong wear resistance and anti-fatigue performance, suitable for long-time heavy transportation.
1.3 Double-Layer Sealing System
Dual rubber labyrinth sealing structure is equipped inside the unit. High-temperature resistant nitrile rubber sealing rings cooperate with metal dust-proof covers to form dual protection. It effectively blocks mud, rain, sand and sewage intrusion, prevents grease leakage, and avoids early bearing failure under mining, construction and coastal saline road conditions.
1.4 Pre-Grease Assembly Technology
We fill high-temperature and anti-extreme pressure lithium grease into the bearing before delivery under dust-free workshop environment. Uniform grease coverage reduces metal friction; no repeated refueling needed after installation, realizing maintenance-free use.
1.5 Precision Assembly & Dimension Calibration
All rolling steel balls, inner and outer rings are assembled with automated precision equipment. Strict dimensional inspection is carried out according to OEM standard tolerances, ensuring complete interchangeability without modification during replacement.
2. Core Performance Advantages
2.1 High Load Bearing Capacity
Integrated one-piece structure can bear large radial and axial load at the same time, matching heavy-duty trucks, dump trucks, semi-trailers and passenger buses with full-load transportation demand.
2.2 Waterproof, Dustproof & Long Service Life
Double sealing structure isolates external impurities, greatly extending service cycle compared with single-seal ordinary bearings, lowering vehicle maintenance cost.
2.3 Low Noise & Stable Operation
Superfinished smooth raceway minimizes rolling friction, the wheel runs smoothly without abnormal humming during high-speed driving.
2.4 Direct OEM Replacement
Manufactured strictly following original vehicle size standards, plug-and-play installation without extra adjustment, saving repair time for mechanics.
3. Applicable Models & Supply Info

Factory direct wholesale, support customized production according to customer OE numbers, sufficient stock and fast shipment for global auto spare parts distributors and repair shops.
Customer Reviews (3)
We’ve purchased IVOLTECK wheel hub bearing units for two years to supply our truck repair workshops. The dimensional precision is fully consistent with OEM specs, no grinding or adjustment needed during installation. The GCr15 steel material and double sealing structure perform excellently on long-haul fleets, with far fewer early failure complaints than cheap alternatives. Stable stock and fast shipment make it our regular bulk purchasing choice.
This hub bearing unit perfectly fits our local mining and muddy road transport conditions. Dual labyrinth sealing effectively blocks sand, mud and saline rainwater, and pre-filled high-temperature grease realizes maintenance-free use for a long time. It can bear heavy overloads all year round, greatly cutting down the wheel maintenance cost of our dump truck customers. The wholesale price is very competitive for regional distributors.
I mainly deal in semi-trailer spare parts, and this integrated wheel hub bearing unit matches BPW and SAF axles perfectly. The superfinished raceway ensures low-noise stable driving at high speeds. Customers feedback that its service life is twice as long as ordinary single-seal bearings. The factory supports customization based on different OE numbers, which greatly enriches my product lineup.
