FAG Spherical Roller Bearings’ Applications & Buying Guide

What Are FAG Spherical Roller Bearings?

FAG Spherical Roller Bearings are rolling-element bearings designed to accommodate both radial and axial loads in applications where shaft deflection, misalignment, or heavy shock loading is common. Manufactured by the Schaeffler Group in Germany, FAG bearings are engineered for precision, efficiency, and maximum reliability.

These bearings feature barrel-shaped rollers, allowing continuous alignment during operation—making them ideal for heavy-duty industries where reliability is critical.

Key Benefits of FAG Spherical Roller Bearings

• Self-aligning design
  Automatically compensates for shaft misalignment and mounting errors.

• Extreme load capacity
  Handles high radial and axial loads, even in shock-prone environments.

• Long service life
  High-quality materials, optimized roller geometry, and advanced heat treatment extend bearing life.

• Reduced maintenance
  FAG’s advanced sealing and lubrication technology minimizes downtime and lowers maintenance costs.

Buying Guide: How to Choose the Right FAG Spherical Roller Bearing

1. Know your load requirements
   Select a bearing that matches the radial and axial loads of your application.

2. Check the speed limits
   Make sure the bearing is rated for your operating RPM.

3. Evaluate shaft alignment and misalignment tolerance
   Choose a self-aligning model if misalignment is unavoidable.

4. Review internal clearance (C3, C4, etc.)
   Bearings with increased clearance are suited for high-temperature or high-speed conditions.

5. Select the correct bore type
   Straight or tapered bores must match your mounting method.

6. Buy from authorized suppliers
   Ensure you’re getting 100% genuine FAG bearings to avoid costly breakdowns from counterfeit parts.
