3. Technical Description
This is a single-row cylindrical roller bearing designed as a floating bearing, ideal wherever the shaft must be able to move axially relative to the housing (for example due to thermal expansion).
Key design points:
- Cylindrical rollers provide a large contact area with the raceways, giving 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.
- The brass cage offers:
- Very high mechanical strength
- Excellent performance under shock loads and vibration
- Superior dimensional stability at higher temperatures (up to 150 °C)
- Good compatibility with various lubricants
With normal radial clearance and standard tolerance class, this bearing is well suited for general and heavy-duty industrial applications where radial loads are high and operating temperatures can be elevated.
4. Typical Applications
- Heavy-duty electric motors and generators (floating side)
- Industrial gearboxes and drives
- Pumps and compressors in demanding environments
- Steel, paper, and process industry machinery
- Applications with:
- High radial loads
- Axial displacement requirements
- Higher operating temperatures or shock/vibration
5. Key Advantages
- High radial load capacity thanks to cylindrical roller design
- Floating bearing function – safely accommodates axial displacement between shaft and housing
- Brass cage → ideal for high temperature, high load, and shock conditions
- Removable inner ring → easier installation, inspection, and replacement
- Standard clearance and tolerance class → easy interchangeability with equivalent bearings in the same size
