Bearing code that cannot be expressed by common code

bearing code that cannot be expressed by common code

r or WM combined with two or three digits indicates differences with standard design, and these differences cannot be expressed by common code

y and another letter (such as ya, Yb) or a combination of numbers are used to identify non serial changes that cannot be expressed with the current post code

ya--- structural change (comprehensive expression) ya1--- the outer surface of the bearing outer ring is different from the standard design

ya2--- the inner hole of the bearing inner race is different from the standard design. Nano materials can reduce the material cost and start the green printing revolution

ya3--- the end face of the continuous input of the bearing ring is different from the standard design

ya4--- the standard design of bearing ring raceway is different

ya5--- there is a difference in the standard design of the bearing rolling element 3 - the elastic recovery depth after removing the main experimental force F1; Different

yb--- changes in technical conditions (comprehensive expression)
