Heavy Duty 2 Turn Internal Spiral Retaining Ring

Product Description

Heavy Duty Internal Spiral Retaining Rings 304 316 Stainless 


Heavy duty internal spiral retaining rings have no ears in your assembly! Spiral retaining rings are manufactured by coiling the ring from flat wire. This unique process produces a retaining ring that has no protruding ears or burrs to interfere with your assembly. Because coiling produces a retaining ring with no scrap, the heavy duty internal spiral retaining ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys.

No gap – 360° retaining surface;

No protruding ears interfere with mating components (uniform cross-section);

Economically produced in stainless steel because the coiling process produces no scrap;

No -Charge on custom designs;

Easy installation and removal;

Heavy duty internal spiral retaining ring can be made of a variety of materials, such as spring steel, stainless steel, copper and other metal materials can be easily produced, the commonly used heavy duty internal spiral retaining ring materials in the market are carbon spring steel, alloy spring steel 65Mn, etc., stainless steel 304, 316, 17-7PH, beryllium bronze alloy and superalloy and other materials are used in some occasions.


Installation method of heavy duty internal spiral retaining ring

Pry off one end of the retaining ring by hand and insert it into the groove; press and twist the retaining ring around the periphery of the groove until the retaining ring is fully wound into the groove;
Disassembly methods and tools for heavy duty internal spiral retaining ring. The Resilient Spiral Retaining Ring has a standard removable groove for easy removal from the groove. The removable groove creates a small gap between the end of the ring and the shaft or hole, allowing a blunt instrument to be inserted into the end of the ring and pry radially upwards The free end of the retaining ring. Insert a screwdriver or dental pliers behind the removable slot; use a tool to pry up the Z front of the end of the retaining ring; rotate the perimeter of the retaining ring by hand until it disengages from the slot;

Advantages of heavy duty internal spiral retaining ring

  1. The structure is simple, the volume is small, the material is small, and the cost is low; it meets the requirement of small space in the device design, which is suitable for compact design; the minimum number of parts simplifies the design of the connecting device.
  2. Multi-point contact, high level of cooperation, can achieve almost cost-free contact. Guaranteed large current carrying capacity; good electrical conductivity, high electrical and thermal stability.
  3. The contact pressure of each contact point is not high, and it has good wear resistance.
  4. The unique structure enables it to have a wide range of work; it is allowed to have more common service on the contact surface; it has greater adaptability to machining errors and assembly errors.
