“E” Rings/Lock Washers (Retaining Washers For Shafts)&Retaining Washers For Shafts

Open Retaining Rings have an e-shaped opening, also called Flower Retaining Rings or E-shaped Retaining Rings, and are usually used to limit the axial position of bearings. The specifications of our open-end retaining rings are applicable to shaft groove diameters from 1.2mm to 30mm.
The material of the open-end retaining ring is generally spring steel, with a hardness of 460-580hv. Stainless steel is also available, generally with a grade of 1.4122.
Surface Coating: The surface of a spring steel open-end retaining ring is generally blackened and oiled, Due to the deformation of the retaining ring during installation, it is rare to see the surface of electro-galvanized (hydrogen embrittlement fracture risk) and non-electrolytic zinc flake coated (coating flaking) products, the surface of spring steel open end retaining ring is generally blackened and oiled.    

Specific types of retaining rings include: taper pin locking retaining rings, screw locking retaining rings, screw locking retaining rings with locking rings, steel wire retaining rings, elastic retaining rings for holes, elastic retaining rings for shafts, screw-fastened shaft end retaining rings, bolt-fastened shaft end retaining rings, steel wire retaining rings for holes, steel wire retaining rings for shafts, and so on. According to its functional mechanism and structural characteristics, can be divided into two categories cut retaining ring and elastic retaining ring. A cut retaining ring is a kind of shaft retaining ring, With the help of its elasticity and pulling type opening will be retaining ring pressed into the groove, to retain the side of the ring through the end of the hole positioning, to limit the axial displacement of the parts. It is a very important mechanical part, with a wide range of applications, such as hydraulic systems, pneumatic systems, and various mechanical equipment in the shaft groove or hole groove.
