High quality NU,NUP,N,NJ series cylindrical roller bearings

cylindrical roller bearing 1.low noise,high speed,long life 2.ISO9001:2000 standard 3.rapid delivery time,

Cylindrical roller bearing:

Single-row cylindrical roller beaing:    

Features:

1.Improved seal: Contact seal increases resistance to entry of water or foreign substances.

2.High load capacity: When used as a sheave bearing, radial and axial load capacities are increased

3.Corrosion resistance: Phosphate surface treatment improves resistance to rust.

4.Easy to apply grease: Holes provided on inner ring facilitate grease replenishment, even while the bearing is mounted.

5.Fewer surrounding parts: With snap rings for the outer ring, fewer parts are required around the bearing for a more cost-effective sheave.

Double-row cylindrical roller bearing:

Features:

1.Compact structures

2.High stiffness

3.High loading capacity

4.Little deformation

Four-row cylindrical roller bearing:

Features:

Four-row cylindrical roller bearings specially applied to supporting rolls and work rolls of rolling mills required high speed and precision, for example, wire mills, bar and shape mills, cold or hot sheet mills and cogging mills.,cement crusher,etc
