What is a snap ring?<\/h3>\n

A snap ring, also known as a snap ring, a snap ring, or a circlip, is a fastening element used on shaft or hole parts to prevent parts from moving or falling out in the axial direction. It is usually assembled in a shaft groove or a hole groove, and uses elasticity or clamping force to achieve the limit fixing function.<\/p>\n

snap rings are widely used in machinery, automobiles, aviation, home appliances, tools and other fields, and are indispensable precision parts in many equipment. Common materials include spring steel, carbon steel, stainless steel and brass, and the surface can be oxidized, electroplated, blackened, rust-proofed, etc.<\/p>\n

How to measure snap rings?<\/h3>\n

Accurately measuring snap rings is the prerequisite for correct selection and replacement. The measurement content includes outer diameter, inner diameter, thickness, groove width and groove depth:<\/p>\n\n\n\n\n\n\n\n\n

Measuring tools usually use calipers or micrometers to ensure that the measurement is carried out in an undeformed state to obtain accurate values. If it is a standard part, you can check the table according to ISO\/DIN\/JIS and other models.<\/p>\n

Types of snap rings<\/h3>\n

snap rings can be divided into many types according to the installation position, shape and purpose:<\/p>\n

    \n
  1. snap rings for shafts (external snap rings): installed on the shaft groove to prevent the parts from moving outward along the axial direction<\/li>\n
  2. snap rings for holes (internal snap rings): installed in the hole groove to prevent bearings and other parts from sliding inward<\/li>\n
  3. E-type snap rings: similar to the “E” shape, easy to install and disassemble quickly, used for small bearings and motors<\/li>\n
  4. Spiral snap rings: spirally wound, suitable for high-speed rotating systems<\/li>\n
  5. Wave snap rings: with buffering and elastic characteristics, suitable for parts with limited preload space<\/li>\n
  6. Constant pressure snap rings: self-adjusting force control, used in temperature difference or force change occasions<\/li>\n
  7. Holeless snap rings (closed type): no installation holes, special methods are required for disassembly and assembly, suitable for closed structures or micro components<\/li>\n<\/ol>\n
