Product Details

High quality cylindrical roller bearings N310

1.Deascription of bearing N310:

(1) Size:50x110x27mm

(2)Delivery:within 5 working days.
(3)Quatity:ISO9001:2000,C/Q
(4)Service:OEM

2. Bearing N310 feature:

1) the roller and raceway for the line contact or offline contact, radial load capacity is big,

apply to under heavy load and shock load.

2) the coefficient of friction small, suitable for high speed, the limit speed close to the

deep groove ball bearings.
3) N and NU type axial movement, can adapt shaft caused by thermal expansion or

installation error and shell

the change of relative position, can be used for free end bearing.
4) on the shaft or hole processing the demand is higher, bearing outer axis relative

deflection after installation to kept under strict control, so as to avoid stress

concentration caused by contact.
5) inner ring or outer ring separable, easy to install and remove.

3. Bearing N310 characteristics:
Cylindrical roller and raceway is line contact, great capacity of radial load, applies to

carry heavy load and impact load, also suitable for high speed rotation.
Cylindrical roller bearing raceway and rolling body geometry after design improvements,

has high bearing capacity, guard and roller end face of the new structure design, not

only can improve the bearing axial bearing capacity, at the same time improved the

lubrication of roller end face contact with the rim area conditions, improve the bearing

performance.

4. Bearing NUP312 application:

Largre and medium-sized motor, locomotives, spindle, internal combustion engines,

generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation

machinery, etc.
