Types of Retaining Rings We Manufacture

 

As a professional custom retaining ring manufacturer in China, Zeyao Hardware supplies a wide range of retaining rings for different shaft and bore retention applications. Whether you need standard retaining rings or custom-designed solutions, we can manufacture products according to international standards or your specific engineering requirements.

 

Internal Retaining Rings

Internal retaining rings are installed inside a bore or housing to securely hold bearings, bushings, gears, and other components in place. They are widely used in automotive transmissions, hydraulic systems, industrial machinery, and precision equipment where reliable internal retention is required.

 

External Retaining Rings

External retaining rings are designed to fit around a shaft and prevent axial movement of components. They are commonly used in motors, gearboxes, agricultural machinery, pumps, and mechanical assemblies that require secure shaft positioning.

 

E-Clips

E-clips provide a quick and efficient fastening solution for grooved shafts. Their simple installation and removal make them ideal for automotive assemblies, household appliances, electronic products, and light industrial equipment.

 

Snap Rings

Snap rings are one of the most widely used retaining solutions for rotating equipment. Available in various sizes and materials, they provide dependable retention for bearings, gears, pulleys, and other mechanical components while allowing easy maintenance and replacement.

 

Custom Retaining Rings

In addition to standard products, we specialize in manufacturing custom retaining rings based on customer drawings, samples, or technical specifications. Our engineering team supports non-standard dimensions, special materials, custom hardness, surface finishes, and application-specific designs for demanding industrial projects.

 

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.

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).
