Post code

Slewing bearing the post code is expressed with letters and numbers bearing structure, tolerances and materials special requirements, etc. Post code a lot of content, here are a few commonly used code.
A) the internal structure of code is the same type of bearing different internal structure, the basic code followed by the letters represent. Such as: contact angle of 15 °, 25 ° and 40 ° of angular contact ball bearings were used C, AC and B represent different internal structure.
2) bearing tolerance class is divided into 2, 4, 5, 6, 6X-level and 0 of 6 levels, followed by the senior to lower its code-named / PZ, / P4 '/ PS, / P6, / P6X and / PO. Tolerance level in, 6X grade applies only to tapered roller bearings; 0 for the general level, the wheel does not mark the order code. .
3) common bearing radial clearance series is divided into a group 2, 0, group 3, 4 and 5 groups of 6 groups were small to large radial clearance. o group of clearance is commonly used groups of clearance in the bearing code is not marked, the rest of the code in the bearing clearance groups, respectively, with / CI, / CZ, / C3, / C4, / CS representation.
3. Prefix
Bearing Prefix used to indicate the bearing subassembly with letters. If L is separable bearings with separable rings; K represents the bearing rolling elements and cage assembly and so on.
The practical application of the rolling bearing type is many, the corresponding bearing code is more complex. Described above code is the most basic bearing code, the most commonly used part, familiar with this part of the code, you can choose to identify and investigate common bearings. About rolling code method can be found in the detailed GBT272-93.
