Product Description

The 30203 Tapered Roller Bearing Product Overview

The 30203 bearing is a precision-engineered Tapered Roller Bearing, specifically categorized within our comprehensive range of Inch Tapered Roller Bearings. This assembly comprises an inner ring (cone) with rollers and a cage, and an outer ring (cup), designed to be separable for easier mounting and maintenance. With a bore diameter of 17 mm, an outer diameter of 40 mm, and an overall thickness of 13.25 mm, the 30203 is adept at supporting high radial loads and substantial axial loads in one direction simultaneously. Its robust design ensures reliable performance in demanding industrial and automotive applications where heavy loads and shock are common.

30203 Bearing Features
