How to measure the size of double snap ring? Now let’s talk about this topic. The circlip for shaft is an axial movement installed on the grooved shaft and used to fix parts. When measuring the inner diameterof this type of circlip, it is slightly smalller than the assembly shaft diameter(the exact size should e checked according to the standard, as it varies). For purchasing purposes, measure the outer diameter of the shaft directly.
The shaft is represented by the specification of the retaining ring: it is determined according to the shaft diameter you use. For example, your shaft diameter is 50mm, which is expressed as: circlip 30gb894.2-1986894.1-1986 circlip for type a shaft. Marking example: shaft diameter d0=50mm, 材料 65mn, heat treatment hrc44 ~ 51, marking of circlip for type a shaft after surface oxidation treatment: circlip gb894.150, the same is for circlip for hole, and the inner diameter of hole is measured directly. For example, aperture 40mm,: will be expressed as: retainer ring 40gb893.1 (circlip for type a hole) example of circlip marking for hole: aperture d0=40, material 65mn, heat treatment hrc47 ~ 54, marking of circlip for type b hole after surface oxidation treatment: retainer ring gb893.240 such as: marking of circlip for type a hole: retainer ring 40gb893.1.
