FAG 21304-E1 TVPB Spherical Roller Bearing 20x52x15 mm

Compact spherical roller bearing for industrial applications

High load capacity, self-alignment and reliable performance

The FAG 21304-E1 TVPB is a compact spherical roller bearing designed for demanding industrial environments where durability, precision and stable operation are essential. Featuring a 20 mm bore, 52 mm outer diameter and 15 mm width, it delivers high radial and axial load capacity while maintaining minimal installation space. Its self-aligning capability compensates for misalignment of shaft and housing, ensuring uninterrupted performance even under mounting imperfections or shaft deflection. The TVPB cage design provides optimized roller guidance and improved fatigue life under heavy and dynamic loads.

Key advantages and performance features

• Self-aligning capability — compensates for angular misalignment during operation

• High radial and axial load capacity in a compact bearing envelope

• Stable performance under vibration and impact loads

• Improved cage design (TVPB) for extended service life and lower friction

• Ideal for medium-duty industrial applications requiring precision and reliability

• Suitable for gearboxes, conveyors, pumps, machinery drives, processing equipment and auxiliary systems

Main description

The FAG 21304-E1 TVPB spherical roller bearing is engineered for industrial equipment where compact size, reliability and robustness are key performance factors. Its barrel-shaped rollers enable efficient distribution of heavy radial loads and axial loads in both directions. The spherical raceway design ensures automatic self-alignment, making the bearing highly tolerant to shaft misalignment and housing deformation — ideal for installations experiencing vibration, temperature variation or structural movement.

The reinforced TVPB cage reduces friction and roller tilt, enhancing operational stability and extending service life in high-duty cycles. Designed for continuous operation and dynamic load environments, this bearing is widely used in gearboxes, conveyor systems, compact industrial machinery, mechanical drives and auxiliary industrial devices.

This model is particularly valued for its compact geometry, enabling integration where installation space is restricted while maintaining high durability and mechanical efficiency. Reduced downtime, increased reliability and lower maintenance requirements provide long-term value in demanding production systems.
