3. Technical Description

This premium single-row cylindrical roller bearing combines:

✔ Brass Cage

• High mechanical strength
• Exceptional performance under heavy loads
• Resistant to vibration and shock
• Excellent high-temperature stability
• Superior lubrication retention

✔ Slightly Increased Radial Clearance

Allows for:

• Better tolerance of thermal expansion
• More stable performance under high load or misalignment
• Reduced friction at elevated operating temperatures

✔ Improved Interior Construction

• Enhanced roller and raceway geometry
• Lower friction
• Increased load distribution efficiency
• Longer service life

✔ Floating Bearing Design

Absorbs axial displacement between shaft and housing—ideal for long shafts or thermally expanding systems.

✔ Removable Inner Ring

• Makes mounting/dismounting easier
• Perfect for interference fits
• Allows easier inspection and maintenance

Manufactured in Germany, this bearing delivers exceptional precision, durability, and reliability in the most demanding industrial environments.
