Cylindrical Roller Bearings – NU, NJ, NUP Types

Cylindrical roller bearings are essential components in industrial applications where high radial loads, precision and long service life are required. We supply NU, NJ and NUP type cylindrical roller bearings from leading global manufacturers and can ship worldwide with fast and reliable delivery.

What Are Cylindrical Roller Bearings?

Cylindrical roller bearings use rolling elements shaped as cylinders instead of balls. This design provides a larger contact surface and therefore significantly higher load capacity. These bearings are ideal for electric motors, gearboxes, pumps, compressors, heavy machinery and many other industrial environments.

Main Types We Supply

NU Type

• Outer ring with two ribs
• Inner ring without ribs
• Allows axial movement in both directions
• Suitable for floating bearing arrangements

NJ Type

• Outer ring with two ribs
• Inner ring with one rib
• Can handle limited axial load in one direction
• Common in electric motors and gearboxes

NUP Type

• Outer ring with two ribs
• Inner ring with one fixed rib and one loose ring
• Handles axial loads in both directions
• Often used for locating bearing positions
