322748 Metric Tapered Roller Bearing 70x130x42mm
- Universal Interchangeability: Functions as a direct cross-reference replacement for identical dimensional equivalents like SET1165, 538971, and T2ED070 in global catalogs.
- Precision Hand-Assembly: Ensures perfectly matched rollers and raceways, eliminating the micro-vibrations often found in mass-produced automated bearings.
- Separable Cup & Cone: Facilitates rapid installation, inspection, and precise setting of bearing end-play during vehicle axle rebuilds.
- High Wear Resistance: Deeply case-hardened GCr15 steel prevents raceway pitting and micro-spalling under continuous operational stress.

Q: How is the quality guaranteed?
A: Rather than relying on automated machinery, our assembly operations take place in a controlled space focused entirely on manual assembly, meaning every single piece is inspected by human hands before it goes into the box.
