Double row self-aligning ball bearings 2203

Double row self-aligning 2203 bearings offer misalignment compensation with dual-row design. The 2203 self-aligning bearings ensure smooth operation under axial/radial loads. Self-aligning double row 2203 features robust construction for industrial applications.

Specification

SEODescription

The Double row self-aligning 2203 bearings are designed with dual-row ball configurations and a spherical outer ring raceway, enabling automatic misalignment compensation up to ±3° to accommodate shaft deflection or mounting errors. The 2203 self-aligning bearings feature a 17 mm bore, 40 mm outer diameter, and 16 mm width, supporting dynamic/static load capacities of 7.8 kN/3.2 kN with a maximum speed rating of 8000 rpm. Constructed from chrome steel with stamped steel cages, these Self-aligning double row 2203 units operate efficiently in temperatures ranging from -30°C to +120°C. Widely used in mining, agricultural machinery, and conveyor systems, their key advantages include reduced friction, vibration resistance, and extended service life under heavy radial loads. Limitations include lower axial load tolerance and potential lubrication challenges in extreme contamination environments.
