Hub Unit Bearings
Hub bearing units are developed based on standard angular contact ball bearings and tapered roller bearings. They integrate two sets of bearings into one unit, featuring excellent assembly performance, the ability to omit clearance adjustment, lightweight, compact structure, large load capacity, pre-lubrication with grease for sealed bearings, eliminating the need externally apply seals, and maintenance-free advantages. They have been widely used in passenger cars and are gradually being increasingly applied in heavy-duty vehicles.

We have a complete production chain for bearings, with rigorous quality control at every production stage. From raw material processing and machining to heat treatment, grinding, assembly, cleaning, lubrication, and packaging, we ensure each step meets high standards of precision and reliability.
How to select the right rolling bearing based on bearing load types?
- Radial loads (load perpendicular to the shaft): Choose standard cylindrical roller bearings.
- Axial loads (load parallel to the shaft): Choose cylindrical thrust bearings.
- Combined radial and axial loads: Choose tapered roller bearings.
What is bearing lubrication?
Lubrication forms a layer of oil film between the rolling elements and the bearing raceways, helping to prevent friction and overheating. Understanding the lubrication requirements of your industry is crucial for selecting the appropriate bearings, as improper lubrication is one of the most common causes of bearing failure.
What is the role of bearing lubrication?
Applying lubricants between the rolling and sliding parts of bearings helps increase speed and prolong lifespan. Other benefits of lubrication include:
- Reduction of noise and vibration
- Heat dissipation
- Sealing
- Corrosion protection
- Long-term maintenance-free operation
