3. Technical Description
This bearing is a single-row cylindrical roller bearing designed as a floating bearing, ideal for applications where the shaft must be able to move axially relative to the housing due to thermal expansion or assembly conditions.
Key design features:
- Cylindrical rollers provide a large contact surface with the raceways, resulting in very high radial load capacity and stiffness.
- The inner ring is removable from both sides, which simplifies mounting and dismounting, especially when using interference fits on the shaft or in the housing.
- The polyamide cage offers:
- Low friction and reduced heat generation
- Quiet running
- Good high-speed performance within the stated temperature range
With normal radial clearance and standard precision, this bearing is well suited for general-purpose industrial applications with significant radial loads and moderate speeds.
4. Typical Applications
- Electric motors and generators (as floating bearing position)
- Gearboxes and industrial drives
- Pumps and compressors
- Fans and blowers
- Steel, paper, and processing machinery
- General mechanical engineering where:
- High radial loads are present
- Axial displacement between shaft and housing must be accommodated
5. Key Advantages
- High radial load capacity thanks to cylindrical roller design
- Floating bearing functionality – absorbs axial displacement safely
- Removable inner ring for easier installation, inspection, and replacement
- Polyamide cage → low friction, quieter operation, reduced operating temperature
- Standard tolerance and clearance → easy to replace and combine with other bearings in the same system
- Robust design suitable for demanding industrial environments
