213 Series Spherical Roller Bearings

🎯 Self-Aligning & Stable Operation

213 series spherical roller bearings feature a double-row roller design and spherical outer raceway, providing strong self-aligning performance to effectively compensate shaft misalignment and mounting errors. They ensure smooth running, reduce vibration, and prevent premature wear under continuous working conditions.

⚙️ Reliable Load Capacity & Structure

Constructed from high-quality bearing steel with optimized roller and cage design, this series offers excellent radial load capacity and moderate axial load resistance. With high rigidity, good wear resistance and standard precision, it supports stable performance for medium to heavy-duty mechanical applications.

🛠️ Widely Used in Industrial Equipment

Widely applied in conveyors, fans, pumps, reducers, agricultural machinery, textile machines, food processing equipment and general mechanical transmission systems, especially suitable for scenarios requiring steady operation and easy installation.

Category Overview

Spherical Roller Bearings are double-row, self-aligning rolling bearings with barrel-shaped rollers and a spherical outer raceway. They are specially designed to accommodate heavy radial loads, impact loads, and moderate axial loads, while automatically compensating for shaft deflection and mounting misalignment.With exceptional rigidity, durability, and low maintenance requirements, they are widely used in heavy industrial machinery operating under severe conditions.
