Product Details

Bulldozer Bearing Manufacturer,Cylindrical Roller Bearing NJ2314 For Dulldozer D50

Product Description

The Introduction of Cylindrical Roller Bearing:

The internal structure of cylindrical roller bearing is made up the rollers which is 90 ° vertically cross wiith each other (this is also the origin of the name cross roller bearing ), with intervals between roller holder or the isolation piece, it can prevent mutual friction between roller and roller, effectively prevent the rotation torque increases.

The roller and raceway surface of cylindrical roller bearing is line contact,so the bearing has high carrying radial load capacity,applicable to carrying heavy load and shock load.Besides,owing to its structure,it's easy to high accuracy processing,applicable to highrate rotary.Inner ring and orter ring are separable,convenient for mounting and dismounting.

The advantages of cylindrical roller bearing:

♦ low friction and high speed

♦ high carrying capacity

♦ high stiffness

♦ can be separable

♦ easy to install and disassemble

Different Characteristics for Different Cylindrical Roller Bearings:

The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.

The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.

The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore

suitable for the axial location of a shaft in one direction.

The outer ring has one integral flange and the inner ring two integral flanges.

The outer ring has one integral flange and one non-integral flange in the form of a loose flange ring and the inner ring two integral flanges.

NUP

The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.

No outer ring and the inner ring two integral flanges.
