Cylindrical roller bearing NNCF4848A/NNCF4848CV
1.Through the fatigue life test of cnas rolling bearing
Running more than 8 hours a day,longer life
2.High quality bearing steel
Smooth and high wear resistance,through high temperature material and high temperature resistant process.seiko production more wear-resistant,longer life
3.Run more quietly
The roller is highly finished,precision design,to ensure that the performance of each product and the unit device precision match
4.Suitable for most equipment operation
CN standard clearance,it can ensure that the working clearance of bearings is close to zero,which is suitable for the operation requirements of most equipment,thus prolonging the life of bearings and reducing the heat,vibration and noise of bearings.

Cylindrical roller and raceway are in linear contact, the radial load capacity is large. Suitable for bearing heavy load and impact load, but also suitable for high-speed rotation.
Cylindrical roller bearing raceway and rolling body are geometric shape. After the improved design, it has a higher bearing capacity. The new structure design of the guard and roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication conditions of the contact area between the roller end face and the guard, and improves the service performance of the bearing.
