Earringless Elastic Retainer, also known as Earringless Retainer or Equal Section Retainer. Compared to the national standard hole retainer, the earringless retainer has an equal cross-section without protruding "ears." Made from flattened wire, the earringless retainer boasts excellent elasticity and toughness after heat treatment and surface processing. The earringless retainer features the following characteristics:

· Equal cross-section, even load distribution, reduces stress concentration phenomena.

·Smooth and complete inner and outer edges, without ears interfering with mating parts

· Seamless internal and external diameters, easy to disassemble

· Virtually no scrap waste is produced during the production process, saving materials.

· No mold required; easily customizable for lightweight, medium, and heavy-duty versions by adjusting material thickness.

·Short production cycle, wide range of materials available, including spring steel, stainless steel, copper, and other metals, all can be produced conveniently.

Due to these many advantages, the earless retaining ring has been widely used in hydraulic component assembly, valves, instruments, various lock components, gears, needle roller bearings, pulleys, connectors, quick connectors, and other mechanical assemblies, gradually replacing traditional ear-type stamping retaining rings in many applications.

Material for earless elastic retaining ring: spring steel, stainless steel SUS304, SUS316, 17-7PH, etc., and other materials as required.
