● Introduction

6221 ZZ bearing belongs to single row deep groove bearings. It is produced by our company in accordance with the national standard GB/T 276-2013, and the bearing‘s groove is super-finished. The company is committed to providing customers with stable and competitively priced high quality bearing products. The material of the bearings is GCr15, which is in accordance with ISO 683-17:2014 and has good impact toughness and fracture toughness. GCr15 is the most widely used high-carbon chromium bearing steel. The noise of the bearing conforms to the national standard JB/T 7047-2006. The noise level of the bearings is divided into Z,Z1,Z2,Z3 and Z4. The sources of bearing noise are vibration of bearing structure, vibration caused by ripple degree of parts surface, vibration of cage and vibration caused by dust. Bearings are widely used in automobiles, household appliances, textile machinery, industrial pumps, internal combustion engines, machinery industry and other fields.

● Production Details

Collar tempering stability is the maximum hardness difference between the corresponding points before and after the second tempering of the measured collar. The hardness difference is not more than 1HRC is qualified. After quenching and tempering the bearing collar, the tempering stability must be tested. Collar turning process needs to check the outer diameter of the collar round deviation, measured by the three-point method on the V-shaped block, the collar will be rotated for more than a week, the difference between the maximum and minimum size measured in the same radial plane. Because of the effect of clamping deformation of turning process is easy to appear three diamond shape, so more use 60° V-shaped block measurement. The center line of rotation of the workpiece and the reference end face are not perpendicular in collar processing because the workpiece end face of the previous process is scratched or the chuck support surface has dirty objects to clamp the material incorrectly. The vertical deviation of the blank itself is large, or there is black skin to make the workpiece shake and produce the phenomenon of double reflection and it is difficult to correct because the margin is too small.

● Technical Parameters

The standard of boundary dimensions is ISO 15: Rolling bearings - Radial bearings - Boundary dimensions, general plan.

● Tolerance and Radial Clearance

The standard of tolerance is DIN 620-2: Tolerances for rolling bearings.
