📝 Category Detail

2300 series are heavy-duty double-row self-aligning ball bearings engineered with a spherical outer raceway, enabling automatic compensation for shaft misalignment, deflection, and mounting errors. This unique self-aligning design ensures stable operation even under heavy radial loads, shock, and vibration, making them ideal for applications with shaft alignment challenges.

Manufactured from premium GCr15 (100Cr6) high-carbon chromium bearing steel with precision heat treatment and strict quality control, these bearings deliver exceptional load capacity, wear resistance, and long service life. The double-row structure provides high rigidity and bidirectional load support, while standard metric dimensions guarantee full interchangeability with international brands.

Category Overview

Self-aligning Ball Bearings are double-row radial ball bearings with a spherical outer raceway, designed with strong self-aligning performance. They can effectively compensate for shaft deflection and installation misalignment, while bearing radial loads and slight axial loads.With low friction, quiet running and easy installation, they are widely used in light to medium‑duty equipment where shaft misalignment is common.
