Needle Bearing Solid Ring NA4912 For Automobile High Load And High Speed
Needle Bearing Inner Ring, Features,
1. Needle bearing solid ring with needle bearing with inner ring.
2. Mainly used in engineering machinery bearings, automotive engine bearings, mechanical sensor bearings.
3. To bearing of high-precision requirements, it is required to inform the precision grade. To needle roller bearing with or without inner ring, whose radial clearance is flexible, it is also suitable.
Needle bearing inner ring, Specification,
1. Please note supplementary code of bearing code when orders exterior ring of arc shape; so does order exterior ring with lubricate hole.
2. The bearing ring of grinding function is necessary with the purpose to get high-precision bearing device.
3. Then the interior ring grinded after being assembled so as to improve rotating precision.
