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 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.
A spiral retaining ring, also known as a spiral elastic retaining ring, is rolled from flat metal wire and has good elasticity and toughness after heat treatment and surface treatment. For shafts and holes, single-turn, double-turn, and multi-turn according to different loads, for axial positioning.
Spiral retaining ring has the following characteristics:
Spiral retaining rings are widely used in hydraulic parts assembly, valves, instruments, various lock core components, needle roller bearings, pulleys, connectors, quick connectors, and other mechanical assemblies.

Spiral retaining rings are a type of retaining ring that uses a spiral groove to hold the ring in place. They are ideal for applications where space is limited, and they can be used with or without a retaining wall. A spiral retaining ring is a type of ring that has a spiral-shaped groove on the inside diameter. This groove allows the ring to be installed on a shaft by being compressed onto the shaft. Once the ring is in place, the groove expands and locks the ring in place.
Spiral retaining rings work by using a spiral shape to hold a shaft in place. This spiral shape creates a friction fit that holds the shaft in place. This is a very effective way to hold a shaft in place, and it is very reliable.
Spiral retaining rings are often used in applications that require a large amount of radial force. They are also used when there is a need to maintain the alignment of the shaft and bore.
There are a few factors that you need to consider when choosing the right spiral elastic retaining ring for your application. The size and shape of the part you are trying to retain, the force required to retain the part, and the environment the part will be in are all important factors to consider.
The size and shape of the part you are trying to retain are important because you need to make sure the ring will fit around the part. The force required to retain the part is important because you need to make sure the ring can withstand the force that is being applied to it. The environment the part will be in is important because you need to make sure the ring can withstand the conditions it will be exposed to.
Spiral elastic retaining rings are different from traditional retaining rings in a few ways. First, spiral elastic retaining rings are made of elastic material, which allows them to stretch and contract as needed. This makes them ideal for use in applications where the surrounding material may flex or change size. Second, spiral elastic retaining rings have a spiral-shaped groove on the inside surface, which helps them grip the surrounding material more securely. This makes them less likely to slip out of place, even under heavy loads. Lastly, spiral elastic retaining rings are more flexible than traditional retaining rings, making them easier to install and remove.
When choosing a spiral retaining ring, there are several factors to consider, including:
By considering these factors, you can be sure to select a spiral retaining ring that is well-suited to your application and will provide reliable performance over time.
