02475/02420 Imperial Tapered Roller Bearing

Enhanced Inner Bore: Features a 31.75 mm bore on a standard 68.263 mm outer cup for optimized shaft design flexibility.
Separable Design: Outer ring (cup) and inner assembly (cone and rollers) mount independently for faster installation.
Low Friction Torque: Precision-ground raceways ensure minimal operating resistance and reduced heat generation.
High Wear Resistance: Deep case-hardened steel prevents raceway spalling during prolonged continuous duty.

Product Introduction

The 02475/02420 is a precision-engineered inch-series tapered roller bearing built to handle demanding radial and thrust load combinations within compact machinery housings. Utilizing the robust 02420 outer cup combined with a 31.75 mm bore 02475 cone, its exact boundary dimensions are 31.75 x 68.263 x 22.225 mm. Manufactured from high-purity GCr15/SAE 52100 bearing steel, this model undergoes state-of-the-art heat treatment to deliver exceptional fatigue life, low running friction, and reduced operational noise under high torque conditions.

Applications

Automotive wheel hubs and steering assemblies.
Commercial vehicle light transmissions and transfer cases.
Agricultural machinery and compact industrial gear reducers.

FAQ

Q: Can the 02475 cone be used with other outer cups in the 02400 series?
A: Yes, in standard inch-series taper designs, cones and cups within the same series family are interchangeable, provided tolerances are verified.
Q: Is this bearing supplied pre-greased?
A: It comes coated in protective anti-rust oil. Operators should pack it with grease or install it in an oil-bath system before operation.
