3. Technical Description

This bearing is a single-row cylindrical roller bearing designed as a floating bearing, ideal when the shaft must be free to move axially relative to the housing (for example, due to thermal expansion).

Key technical features:

• Cylindrical rollers provide a large contact surface with the raceways, giving very high radial load capacity and good stiffness.
• The inner ring is removable from both sides, making mounting, dismounting, and inspection easier, especially when using interference fits.
• The polyamide cage offers:
• Reduced friction and heat generation
• Quiet, smooth running
• Good high-speed capability within the specified temperature range

The important difference vs. the standard version is the slightly increased radial clearance. This extra clearance is beneficial when:

• Operating temperatures are higher and thermal expansion is expected
• Fits are tighter (e.g. heavy press fits on shaft or in housing)
• There is a risk of internal preload developing at operating conditions

This makes the bearing more tolerant of misalignment, thermal growth, and heavy operating conditions, while still providing precise guidance.

4. Typical Applications

• Electric motors and generators (floating bearing side)
• 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 needs to be absorbed
• Slightly increased internal clearance is preferred

5. Key Advantages

• High radial load capacity due to cylindrical roller design
• Floating bearing function – safely accommodates axial displacement
• Slightly increased radial clearance → better behavior under heat and tight fits
• Removable inner ring → easier assembly, disassembly, and inspection
• Polyamide cage for low friction and quieter operation
• Standard tolerance class for easy interchangeability and integration
