Postcode - Bearing Clearance

C1——The clearance conforms to Group 1 specified in the standard, and is less than Group 2.

C2—— Clearance conforms to group 2 specified in the standard, and is less than group 0.

C0—— Clearance conforms to group 0 stipulated in the standard, omitted in the code, not indicated.

C3—— Clearance conforms to Group 3 stipulated in the standard, and is greater than Group 0.

C4——The clearance conforms to the 4 groups stipulated in the standard, and is greater than 3 groups.

C5——The clearance conforms to the 5 groups stipulated in the standard, and is greater than 4 groups.

When the tolerance grade code and the clearance code need to be expressed at the same time, the combination of the tolerance grade code (not indicated for P0 level) and the clearance group number (not indicated for group 0) is used.

Example: P63=P6+C3, which means the tolerance class of the bearing is P6, and there are 3 groups of radial clearance.

P52=P5+C2, means bearing tolerance class P5, radial clearance 2 groups.

Non-standard clearance, in the case of special radial clearance and axial clearance, the relevant limit value should be expressed in μm after the letter R (radial clearance) or A (axial clearance), and the number Separate them with dots.

Example: 6210.R10.20 - 6210 bearings, radial clearance 10 μ m to 20 μ m.

6212.A120.160 - 6212 bearings, axial clearance 120 μm to 160 μm. Subsequent code — bearings tested for noise

F3—— Low noise bearing. It mainly refers to cylindrical roller bearings and deep groove ball bearings with inner diameter d > 60mm or more. Example: 6213.F3.

G——Low noise bearing. Mainly refers to deep groove ball bearings with inner diameter d ≤ 60mm. Example: 6207.G
