The basic code indicates the basic type of FAG bearing
Core Tip: The basic code indicates the basic type, structure and dimensions of the FAG bearing. The pre-code indicates that the bearing parts are placed before the basic code. FAG's bearing code is based on the basic code, pre-generation
The basic code indicates the basic type, structure and size of the FAG bearing. The pre-code indicates that the bearing part is placed before the basic code. FAG's bearing code consists of the basic code, the pre-code and the post code. The basic code indicates the basic type, structure and size of the bearing. The leading code indicates that the bearing part is placed before the basic code. The post code indicates the supplemental code added after the basic code of the bearing when the bearing structure shape, size, seal, cage, tolerance, clearance, heat treatment, packaging, technical requirements, etc. are changed.
1 pre-code
The pre-code R is placed directly before the basic code of the imported bearing, and the remaining pre-codes are separated from the basic code by small dots.
GS—Thrust cylindrical roller bearing race. Example: GS.81112
K – the combination of rolling elements and cages. Example: K.81108 assembly of thrust cylindrical roller and cage.
R – without bearings that separate the inner or outer ring. Example: RNU207 - NU207 bearing without inner ring.
WS—Thrust cylindrical roller bearing shaft ring. Example: WS.81112.
2 post code
The post code is placed after the basic code. When there are multiple sets of post code, it should be arranged from left to right in the order of the post code listed in the INA bearing code table. Some post-codes are separated from the base code by small dots.
