Bearing products technical requirements

1, finished product size bearing and rotating precision tolerances shall comply with GB/T307. 1, JB/T10336 and related requirements of this agreement. 2, the residual magnetic requirements shall meet the requirements of standard JB/T6641 3, bearing clearance requirements: we require testing axial clearance, testing apparatus for X193, load on 20 kg, 10 kg under load. Common type axial clearance criteria such as table 1, the products are not listed in table 1 the axial clearance standard need to ask for our confirmation before processing. 4, bearing cleanness-degree cleaning rust after finished bearing, its average cleanliness allows each containing sludge volume index according to standard JB/T7050 execution. 5, finished product bearing rotating flexible bearing demagnetization should rotate flexibility and so check after cleaning. Spinning process requires fast, flexible, smooth and can keep certain duration and no the phenomenon of excessive vibration and sudden braking. In the process of rotation should be without the noise, including no dust noise and maintain sound, etc. So good, do not allow the ball out from the cage pocket hole. 6, roughness. The surface roughness of bearing ring should conform to the requirements of the drawings, drawings without annotation should meet the GB/T 307. 3 requirements. 7, 7 bearing assembly quality. After 1 bearing supporting the finished parts assembly, should smooth rotating flexible, no block, abnormal interference or channeling phenomenon. 7. 2 cage after pressing, there is no obvious defects such as displacement, strain, crack, deformation, cage may not touch the ring in the limit position. 7. 3 products should not be short of steel ball bearing, the phenomenon such as mixed ball, off the ball. 8, the service life of bearing, limiting speed, friction torque, rigid, noise and other performance indicators should be consistent with our drawings and relevant standards.
