JB/T 8922-2011 (English Version) PDF

Scope: This standard specifies the N type, NU type, NJ type and NF type whose overall dimensions comply with the provisions of GB/T 283-2007, diameter series 2 and 3, nominal inner diameter is 15mm~120mm, and radial clearance complies with GB/T 4604- Vibration (speed) technical conditions for cylindrical roller bearings with zero clearance (hereinafter referred to as bearings) specified in 2006. The V group specified in this standard is the basic requirement for general bearing vibration (speed), and the bearing is not marked with "V"; V1, V2, and V3 groups are suitable for bearings with vibration (speed) requirements. This standard applies to the production inspection and user acceptance of finished bearings by manufacturers.
