This standard specifies the radial clearance values ​​of the following types of cylindrical bore bearings and tapered bore bearings. A. Deep groove ball bearings (except for outer spherical ball bearings, whose clearance values ​​are specified in JB 5304); b. Self-aligning ball bearings; c. Cylindrical roller bearings; d. Needle roller bearings; e. Spherical roller bearings. The radial clearance values ​​of double-row cylindrical roller bearings are recommended in the appendix. The clearance values ​​given are applicable to bearings without preload and bearings that can withstand pure radial loads in their structure. The clearance values ​​listed in this standard are for subscribers to use when inspecting bearings.

Subject content and scope of application
This standard stipulates the radial clearance of the following types of wide-hole thrust bearings and national standard bearings. The groove ball bearing (except for the outer ball bearing, the clearance value is specified in B5301: a. Self-aligning block bearing; Net column bearing: Needle bearing: Self-aligning lacquer bearing. The longitudinal clearance value of double-row net column roller is introduced in the appendix. The clearance value given in GB/T460493 is applicable to bearings without folding load and bearings that can bear pure radial negative load in structure. The clearance values ​​listed in this standard are for the subscriber to inspect the shaft. 2 Reference standards GB4D9 Definition of dynamic bearing tolerances GB SAC1

Except for the needle roller bearings and heavy series needle roller bearings with internal and external retainers, the radial clearance values ​​of the four-column roller bearings specified in Table 4 are adopted for the needle roller bearings with internal and external retainers (see GB1603) and the internal retainer bearings as separate parts. The radial clearance is determined by the inner diameter of the needle roller assembly: the diameter is specified in GB1603 and GB8. 4.5 The radial clearance of the bearings with radial limit should meet the requirements of Table 5 and Table 6. 4
