8.1 Generally, the inspection is carried out in accordance with ZBJ11020, the AQI. is 1.5, the inspection level is level 1, or the inspection is carried out according to the method specified in the production and user agreement.
8.2 Each set of qualified bearings shall be issued a certificate by the quality inspection department of the manufacturer including the measured data of the following items: single-plane average inner diameter deviation △dmp
a,
single-plane average outer diameter Deviation △Dm
h.
Inner ring radial runout Ki (its highest point position is marked on the end face of the inner ring, symbol is "*") outer ring radial runout Kea (its highest point position is marked On the end face of the outer ring, the symbol is \half") d.
9 Mark, packaging, transportation and storage
9.1 The mark should include the product code, manufacturer code or trademark. 9.2 Bearings that have passed the inspection, The inner packaging shall comply with the provisions of JB/T3034, and the outer packaging shall comply with the provisions of JB/T3016 and JB/F3017
9.3 The appearance of the packaging box shall be marked with the product name, code number, quantity, manufacturer name, and net weight. , gross weight. 9.4 Bearings that have been packaged internally and externally should be guaranteed not to rust within 12 months from the date of shipment under normal storage and transportation conditions.
