Retaining ring DIN 471 for shafts
Retaining rings according to DIN 471 prevent axial detachment on axles, shafts and bolts. The retaining elements are standardised parts and are primarily used in the mechanical engineering field. The retaining rings are equipped with a slot or groove so that they can be positioned precisely on a shaft.
It is possible to mount these retaining elements using an assembly tool. They can be disassembled.
They are available in different sizes for shaft diameters 4 mm to 50 mm in spring steel or stainless steel.

Frequently Asked Questions (FAQ)
What are retaining rings DIN 471 and why are they important?
Retaining rings DIN 471 are mechanical fastening elements that play a critical role in ensuring the stability and integrity of assembled components. They are specifically designed to secure bearings, gears, and other mechanical parts on shafts, axles, and bolts with groove, preventing slip-off and transmitting axial forces.
What material are the DIN 471 retaining rings made of?
The rings are available in steel and stainless steel.
What surface treatments are available?
Bright, electr. galvanised white, mech. galvanised silver and phosphatised oiled.
What areas of application are DIN 471 retaining rings typically used in?
Among other things, they are used in mechanical engineering, heavy industry, electrical engineering and electronics, agricultural machinery, medical technology, energy generation, and in construction and architecture.
What advantages do retaining rings DIN 471 offer?
They ensure standardization and reliability, offer a wide range of applications, are available in various materials, possess increased durability through various surface treatments, and assist in the precise securing of component positions.
How does the flexibility of the size series of retaining rings DIN 471 contribute to their application?
The wide range of standard sizes allows for a precise fit for almost any application, leading to an effective and secure fastening of mechanical components.
What tools are necessary for the installation of a retaining ring DIN 471?
For the installation, a retaining ring pliers is usually required, which is designed for retaining rings DIN 471 and has tips that fit into the small holes of the ring.
What steps should be taken when installing a retaining ring DIN 471?
The installation steps include preparation and cleaning, selecting the correct size, carefully opening the ring with a retaining ring pliers, positioning and installing the ring on the shaft or in the groove, and a final inspection of the installation.
How can you ensure that the retaining ring DIN 471 is correctly installed?
After the installation of the retaining ring, it is important to check if it sits securely in the groove. A correctly mounted ring exhibits minimal rotational movement and is flush with the walls of the groove or indentation.
What should be done if there are issues when installing DIN 471 retaining rings?
Check the size and cleanliness of the slot if the ring does not snap in easily. If a ring is overstretched, a replacement is required. For space limitations, specialized tools like angled pliers may be necessary.
What is the difference between retaining rings DIN 471 and retaining rings DIN 472?
Retaining rings according to DIN 471 (external retaining rings, with outward-facing ends) are designed for use on shafts, axles, and bolts with groove. They are attached to the outside of a shaft and serve to secure components such as bearings, gears, or other machine elements on the shaft and to prevent these parts from moving axially off the shaft.
Retaining rings according to DIN 472 (internal retaining rings, with inward-facing ends), on the other hand, are intended for use in bores. They are installed in a groove within a bore and hold components in place from the inside out to prevent them from slipping out of the bore. Both types of retaining rings have a characteristic C-shape with ends that slightly point outward or inward, to facilitate insertion and removal with the help of a special retaining ring pliers. Despite their similar function and construction, they are designed for different applications, with DIN 471 used on the shaft and DIN 472 used in the bore.
