Stainless Steel Spindle Cylindrical Roller Bearing Single Row NU 308 ECJ , 85mm Bore

Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.

The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring

Features of Cylindrical Roller Bearing

1. High radial load capacity,is suitable for heavy load and impact load.

2. Small friction, suitable for high speed,the limiting Speed is close to Deep Groove Ball Bearings

3. N,NU series can adapt to high temperature and allow error during installation.

4. inner ring and outer ring are separable,easy to install and take down

Basic Dynamic Load Rating:340kN

Basic Static Load Rating:335kN

Material of Rings and Balls: Chrome steel,Carbon steel, Stainless steel

Cage Material: Brass,Steel,Nylon

Cage material of Cylindrical roller bearing:

When the outer diameter is less than (inclusive) 400mm, solid brass cage or steel press cage are adopted for single row cylindrical roller bearing. When the outer diameter is more than 400mm, brass cage and pin-type cage are adopted for four row cylindrical roller bearing.

Application: motor, locomotives, autos,spindle,equipment, internal combustion engine, generator, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.

Single row: NU, NJ, NUP, N, NCF and NJG designs

Double row: NNU, NN and NNF designs
