PRODUCT DETAILS

🎯 Core Feature: Self-Aligning Performance

The 1200 series adopts a single-row spherical outer ring design, which automatically compensates for angular deviation or mounting misalignment during high-speed or continuous operation. This self-aligning capability ensures stable running, reduces shaft vibration, and minimizes wear on housing and connecting components—ideal for motors, pumps, and mechanical transmission systems.

⚙️ Material & Load Capacity Specification

Manufactured from high-quality GCr15 bearing steel with precision grinding processes, the 1200 series supports stable radial loads and moderate bidirectional axial loads. Available in open (standard) and sealed (2RS/ZZ) versions, it delivers low friction, quiet operation, and long service life for continuous industrial environments.

🛠️ Typical Application Scenarios

Widely used in industrial motors, agricultural machinery, building equipment drives, and general manufacturing lines, the 1200 series features compact dimensions, high load resistance, and excellent compatibility with automated production systems.

Common application scenes include:

Conveyor system drives
Water pump & fan units
Textile machinery transmission
Chemical processing equipment motion systems

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.
