3. Technical Description

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

Key technical features:

• Cylindrical rollers provide a large line contact with the raceways, resulting in very high radial load capacity and high stiffness.
• The inner ring is removable from both sides, which significantly simplifies mounting, dismounting, and inspection—especially in applications with tight fits on shaft or housing.
• The brass cage offers:
• Excellent mechanical strength
• High resistance to shock loads and vibration
• Stable performance at elevated temperatures (up to 150 °C)
• Good lubricant compatibility

The slightly increased radial clearance makes this bearing especially suitable when:

• Operating temperatures are higher and thermal expansion must be compensated
• Interference fits are tight and could otherwise reduce operating clearance
• There is a risk of internal preload under working conditions

This combination of brass cage + increased clearance gives a robust solution for heavy-duty, high-load, higher-temperature applications.

4. Typical Applications

• Heavy-duty electric motors and generators (floating bearing position)
• Industrial gearboxes and large power transmission drives
• Pumps and compressors operating at higher temperatures or loads
• Steel, paper, mining, and process industry machinery
• Any application with:
• High radial loads
• Axial displacement between shaft and housing
• Elevated temperature and/or shock conditions

5. Key Advantages

• High radial load capacity from cylindrical roller design
• Floating bearing function – safely accommodates axial shaft movement
• Slightly increased radial clearance – ideal for thermal expansion and tight fits
• Brass cage – excellent for high load, vibration, and up to 150 °C
• Removable inner ring – easier mounting, dismounting, and maintenance
• Standard tolerance class – easy interchangeability with equivalent bearings of the same size
