Cylindrical roller bearing - Cylindrical Roller Bearing

Cylindrical roller bearing


1. Description
The cylindrical roller bearings are separable bearing. The rollers contact raceway
with line-contact. Therefore, the radial load carrying capacity is higher and applies to heavy load, impact load or high rotating speed circumstance. This bearing is easy to be installed and disassembled, especially when the inner ring and outer ring needed to interference fit with shaft and housing.

2. Structure
Single-row cylindrical roller bearing
• no capped edge on inner ring (NU type)
• single capped edge on inner ring (NJ type)
• single capped edge with flat retaining ring on inner ring (NUP type)
• no capped edge on outer ring (N type)
• single capped edge with declining retaining ring on inner ring (NJ+HJ type)
• single capped edge on outer ring (NF type)
Tow-row cylindrical roller bearing
• Tow-row cylindrical roller bearing(NN type)
• tow-row taper holes cylindrical roller bearing( NN…K type)
• no capped edge on inner ring (NU type)
• two-row taper holes with no capped edge on inner ring (NNU…K type)
• taper holes cylindrical roller bearing (NNU…K/W33 type)
• no capped edge on inner ring (NNU…K/W33 type)
• taper holes with no capped edge on inner ring (NNU…K/W33 type)
Four-row cylindrical roller bearing
• FC type
•FCD type
•FCDPtype

3. Cage
