- Scope
- This standard stipulates that the overall dimensions conform to the 0, 2, and 3 diameter series in GB/T 276-1994, the nominal inner diameter is 3 mm to 120 mm, and the radial clearance conforms to the depth of the clearance groups 0, 2, and 3 in GB/T 4604-1993. The vibration acceleration level of groove ball bearings (hereinafter referred to as bearings) and the peak technical conditions of vibration acceleration levels corresponding to groups Z3 and Z4. Group Z of this standard is the basic requirement for the vibration acceleration level of general-purpose bearings. It is suitable for the production inspection of finished bearings by bearing manufacturers. The bearings are not marked with "Z". The ZF3 and ZF4 groups, which have higher requirements for bearing vibration acceleration levels, are suitable for bearing manufacturers' production inspection and user acceptance of finished bearings.
