3. Technical Description

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

Key design characteristics:

• Cylindrical rollers provide a large line contact with the raceways, enabling very high radial load capacity and excellent stiffness.
• The inner ring is removable from both sides, which simplifies mounting, dismounting, and inspection—especially useful when using interference fits on shaft or housing.
• The machined brass cage, guided by the outer ring, offers:
• High mechanical strength
• Excellent performance under shock loads and vibration
• Good dimensional stability at elevated operating temperatures
• Reliable guidance of the rollers, even under heavy load and at higher speeds

This construction makes the bearing suitable for demanding industrial applications where durability, load capacity, and stable running behavior are critical.

4. Typical Applications

• Heavy-duty electric motors and generators (floating bearing side)
• Industrial gearboxes and large drives
• Pumps and compressors
• Steel, paper, and process industry machinery
• General heavy industrial equipment where:
• High radial loads are present
• Axial displacement between shaft and housing must be accommodated
• Robust cage performance is required under tough operating conditions
