3. Technical Description

This single-row cylindrical roller bearing is designed for high-performance industrial applications requiring high radial load capacity, smooth running, and tolerance for axial displacement.

Key technical traits:

✔ Slightly increased radial clearance

Provides:

• Better heat expansion compensation
• Improved performance under higher load or misalignment
• Reduced risk of internal friction during thermal growth

✔ Floating bearing function

Allows the shaft to move axially relative to the housing—ideal for long shafts or thermal expansion scenarios.

✔ Removable inner ring

• Simplifies mounting and dismounting
• Allows use of tight fits
• Suitable for designs requiring frequent inspection or maintenance

✔ Improved interior construction

Optimized roller geometry, better internal finish, and enhanced material performance.

✔ Polyamide cage

• Quiet operation
• Low friction
• Supports higher running speeds

This bearing is crafted in Germany, ensuring premium quality and long, reliable service life.
