R40-101 Precision Tapered Roller Bearing

Dynamic Load Handling: Expertly manages simultaneous radial weight and unidirectional axial thrust forces.
Precision Micro-Finishing: Exacting dimensional tolerances (down to 0.001mm) ensure smooth, vibration-free rotation at high speeds.
Separable Assembly: The cone (inner ring with roller assembly) and cup (outer ring) can be mounted independently, streamlining factory installation. Thermal Stability: Advanced heat treatment allows for stable continuous operation in high-temperature gearbox environments.

Product Introduction

The R40-101 is a highly precise single-row tapered roller bearing designed to deliver exceptional stability and power transmission under heavy combined radial and axial loads. Featuring exact dimensions of 40.000 x 90.000 x 26.250 mm, this bearing provides high structural stiffness for demanding mechanical environments. Forged from premium ultra-clean GCr15 bearing steel, the R40-101 undergoes advanced deep-case hardening to resist subsurface fatigue and abrasive wear. Our automated manufacturing lines ensure precise matching of the cup and cone, providing global B2B distributors and machinery manufacturers with a reliable, low-friction component that minimizes equipment downtime.

Applications

Automotive manual and automatic transmission systems.
Industrial heavy-duty gear reducers and transfer cases.
Agricultural machinery differentials and axle hubs.

FAQ

Q: Can this bearing handle bidirectional axial loads?
A: A single-row tapered roller bearing like the R40-101 can only accommodate axial loads in one direction. For bidirectional support, two bearings must be mounted in an opposing pair configuration.
Q: Is the 26.250mm measurement the total width?
A: Yes, 26.250mm represents the total assembly width (T) when the cup and cone are mounted together.
