Types of Retaining Ring

The retaining rings produced by our company mainly include the following types:

 
 

E Type External Circlip

The E-type external circlip is a fastener with an E-shaped cross-section. Its open E shape provides some flexibility when installed on a shaft. This design allows it to fit shafts of various diameters while providing enough radial force to secure parts effectively.

 
 
 

Bowed W Rings

The bowed W rings are a type of retaining ring used to secure parts against movement on a shaft. The ring's inner diameter is slightly smaller than the shaft. They are installed on the shaft and fit into a groove, using their elastic properties to provide axial positioning.

 
 
 

Bevelled Circlips

The bevelled circlips are designed to be installed into circular holes to fix the axial movement of components. These circlips have an outer diameter slightly larger than the diameter of the hole where they are fitted.

 

 

Advantages of Retaining Ring

Cheaper compared to other fastening methods

Use less raw material for a given size

Reduce and avoid complex machinings such as threads and undercuts

Compact design

It can be assembly quicker

No special training is required for assembly

Lightweight

Easy to install

Unlike threaded alternatives, significantly reduce the production cost

 

 
 
Applications of Retaining Ring
Crescent Rings

Food & Beverage Industry

During food and beverage processing the product often moves through many filtration processes in order to remove impurities. To achieve the required level of filtration there are many filters installed throughout the manufacturing equipment. The appropriate material and size Retaining Ring is often the method of choice to hold these filters in place. Retaining rings are easy to install and can aid with the alignment of the filters.

Single-Turn Spiral External Retaining Rings

Medical Industry

Due to their small size and availability in stainless steel and other special alloys, retaining rings can lend themselves to utilization in surgical instruments, imaging devices and implants. Moreover, they don’t have gaps or lugs making them ideal for tight radial applications.

Automotive Industry

The cars we use today can’t function without the help of retaining rings. They are present in many major and minor components of automobiles. Whether you think of Lifesaving airbags or smooth functioning gear transmission systems, retaining rings play a major role in their functioning. Some of the components where retaining rings are present include: gearboxes, rearview mirrors, steering system, brake pedal assemblies, valves etc.

Bowed W Rings

Oil & Gas Industry

Like other industry applications, retaining rings are very popular in Oil & Gas Industry. Retaining Rings are used in Ball Valves, Gate Valves, Coiled Tubing, Electronic Chassis & Delivery Tools. Often oil and gas industry applications involve extreme environmental conditions, retaining rings are also manufactured in a range of special materials which can withstand these harsh conditions.

 

Material Choices for Retaining Rings
 
 
Carbon Steel

Carbon steel is widely used for its strength and cost-effectiveness, making it suitable for heavy-duty truck parts.
High strength for robust retention.
Cost-effective and versatile.
Suitable for various environments, though less resistant to corrosion.

 
Stainless Steel

Stainless steel is preferred for its corrosion resistance, especially in environments exposed to moisture or chemicals.
Resistant to corrosion, ideal for harsh environments.
Durable with long-term strength retention.
Aesthetic appeal for visible applications.

 
Beryllium Copper and Phosphor Bronze

These materials are used in specialized applications, offering unique properties such as non-magnetic behavior and excellent fatigue resistance.

FAQ

 

Q: How to choose a retaining ring?

A: Free diameter – For internal retaining rings, this is the outer diameter and for external retaining rings, it is the inner diameter.
Ring thickness.
Groove size, including the diameter, width, and depth of the groove.

Q: How does a retaining ring work?

A: Retaining rings work by creating a shoulder to hold components in place on a shaft or inside a bore. They are designed to fit into a machined groove, either on the outside of a shaft or the inside of a bore, and snap into position. This creates a fixed point that prevents the retained component from sliding axially along the shaft or bore.

Q: What is the difference between a snap ring and a retaining ring?

A: The terms "snap ring" and "retaining ring" are often used interchangeably, but a snap ring is a specific type of retaining ring. Retaining rings are a broader category that includes various designs like snap rings, spiral rings, E-clips, and others. All snap rings are retaining rings, but not all retaining rings are snap rings.

Q: Do retaining rings need grooves?

A: Self-locking rings don't need a groove and are ideal for shaft or housing diameters of 1 in. or less. An axial retaining ring is installed into a groove in a shaft or bore along an axis center point and have lugs and lug holes that are used for installation.

Q: Can you reuse retaining rings?

A: Depending on the installation method and installation stress, these rings can often be reused without any issues. If your application requires frequent installation and removal, it would be best to keep the installation stress low to minimize the need for replacement retaining rings.

Q: How to measure retaining ring size?

A: Internal circlips are retaining rings that fit inside a cylindrical bore or housing and push in an outward motion. The best way to find the internal circlip size you need, is to measure the inside diameter of the bore (not the circlip groove).
