JB/T 10237—2001 This standard specifies the vibration (acceleration) technical conditions for finished tapered roller bearings with nominal inner diameters of 15 to 60 mm and 30200, 32200, 30300 and 32300 series in GB/T 297 "Rolling bearings tapered roller bearings dimensions". This standard specifies that vibration (acceleration) group Z is the basic requirement for grade 0 bearings and is applicable to production inspections by bearing manufacturers; groups Z1 and Z2 are applicable to bearings for which users require control of vibration (acceleration) levels. For manufacturer inspection and user acceptance. This standard was first issued in May 2001.
