Standards and Usage of E-type Open Retaining Rings Industrial Solutions

Definition of E-type open-end retaining ring

The open-end retaining ring is also known as the open-end snap ring, open-end snap ring, open-end snap ring, and E-type snap ring. Open retaining ring shape opening into E-shaped, usually used to limit the axial position of the bearing, can prevent the other parts mounted on the shaft from tampering. It is a kind of installation in the grooved shaft, used as a fixed part of the hole to the movement of this retaining ring diameter, where the assembly of the shaft diameter is slightly smaller. The inner diameter of this ring is marginally smaller than the diameter of the assembled shaft. When installing the retaining ring, it is necessary to use the spring pliers to insert the jaws into the hole of the retaining ring and expand the retaining ring before putting it into the pre-processed shaft groove. Open Retaining Ring: The shape of the open retaining ring is E-shaped, which is used for retaining the ring for fixing zero (part) parts on the shaft, and it applies to the available single ring with a nominal diameter of D=1.2~15MM.

1. Open retaining ring: also called open card or E-type card, the leading role is to limit. It is generally used in machine bearings for axial positioning.

2. Shaft elastic retaining ring, also called shaft card or external card, is used to fix the holes-like movement parts to prevent the bearing from unnecessary axial runout.

3. Hole elastic retaining ring: installed in the round hole, used to fix the axial movement of parts.

E-type open-end retaining ring with application solutions

Retaining Rings are generally used to fix rings for bearings, gears, and other shaft parts. Pay attention to the relationship between the outer diameter (D) of the retaining ring and the shoulder diameter (Lo) of the bearing, which needs to meet D<Lo. Otherwise, it may lead to friction between the bearing and the retaining ring to produce resistance and wear. Open-end retaining ring specification range: Φ2-Φ36; heat treatment needs to be quenched and tempered, HRC 44-51 (process reference value); material 65Mn spring steel is the primary material, the surface treatment of the product, the spring steel is heat-treated blackened or phosphatized, to ensure that the hardness, elasticity is uniform, the surface is flush and de-burr. The stainless steel retaining ring surface color is bright.

Fixing the gear on the shaft: The groove on the gear, the depth of the groove, is equal to the diameter of the cylindrical pin. The snap ring is used with the cylindrical pin to fix the gear.

Fixing other parts on the shaft: An E-type cotter retaining ring is used with a cylindrical pin to select the parts.

1. Choose the appropriate E-type circlip, according to the diameter of the shaft and hole, to ensure that it can firmly connect the shaft and hole; check the E-type circlip; before installation, check the E-type circlip for damage, deformation residue, etc., to ensure that it is intact.

2. Preparation of tools: Prepare to install E-type clamp tools required, such as external pliers, internal pliers, etc. Installation of E-type clamp: The E-type clamp will be installed according to the requirements of the shaft and the hole. Use external or internal pliers to compress to the appropriate position of the E-type clamp.

3. check the installation; after the installation is completed, check whether the E-type clamp spring is correctly installed, whether there is displacement, deformation, etc.; test connection; after the installation is completed, test the connection to ensure that the shaft and hole connection is firm and reliable.

Industrial solutions for the design of E-type open-end retaining rings

The crucial part of the design process for open-end retaining rings is ensuring that the ring's nominal diameter, opening, and thickness fit the width and diameter of the groove on the shaft. Different shaft diameters are matched with other types of retaining rings.

The design requirements are summarized in the recommended design dimensions in DIN 6799 "E" for open-end retaining rings. Since the open-end rings are already standardized, it is easy to buy standardized rings on the market as long as they are designed according to the standard. Open-end retaining rings DIN6799 are widely used in agriculture, industry, automobile industry, machinery and equipment, etc. The retaining ring may be used as long as the bearings are rotating. DIN6799 open-end retaining rings are widely used in aerospace, shipbuilding, automobile manufacturing, machinery, and equipment industries.
