Model Number: NJ224EM

Number of Row: Double Row

Structure: Cylindrical

Features:

1. Roller and groove for line contact or repair referral contact, radial load capacity,

is designed to withstand heavy load and impact load.

2. Small friction coefficient, suitable for high speed, limit rotational speed close to

deep groove ball bearing.

3. Ntype and NU type can axial movement and can adapt caused by thermal

expansion or installation error and shell the shaft of relative location changes, can

make free use of the bearing.

4. The hole of shaft or block the demand is higher, bearing processing after

installation relative skewed to outer ring axis and kept under strict control,

lest cause contact stress concentration.

5. Inner circle or their cups are separable, convenient in installation

and removal.

Application:

Locomotives, spindle, internal combustion engines and generators, gas turbines, reducer,

rolling mill, vibrating screen and lifting transportation machinery, etc.
