GQZ 4T-529/522 Single Row Inch Tapered Roller Bearing 76.2×127×36.513mm Separable Matching Assembly

4T-529/522 is single row separable inch-size tapered roller bearing, matched assembly composed of inner cone 529 and outer cup 522. Tapered contact surfaces between rollers and raceways can bear radial load and unidirectional axial load simultaneously. Separable cone and cup simplify installation, disassembly and preload adjustment. Widely used for heavy trucks, semi-trailers and engineering transport machinery transmission systems.

1. Standard inch matched set 529/522, excellent interchangeability for overseas vehicle aftermarket spare parts
2. Tapered raceway structure withstands radial force and one-way axial thrust load at the same time
3. Separable inner and outer components support independent fitting and flexible preload adjustment
4. Precision superfinished roller surface reduces friction heat and running noise during continuous operation
5. Compact overall dimension, suitable for transportation machinery with limited installation space
6. Customizable options: OEM laser marking, high temperature resistant grease, special clearance grades
   Effectively reduce roller fatigue wear and extend service life of vehicle transmission assemblies.
