An external retaining ring DIN 7993 A is a small metal component used to secure other parts on shafts or in bores. It prevents these parts from accidentally shifting during the operation of mechanisms.
Technical Specifications DIN 7993 A
DIN 7993 A is an international standard that defines the dimensions, shape, and materials of retaining rings. This standard ensures that the ring meets specific quality requirements.
- Material: Typically steel with various coatings.
- Dimensions: The diameter, thickness, and width of the ring are defined by the DIN 7993 A standard.
- Accuracy Class: Ensures high manufacturing precision.
Manufacturing Material:
Retaining rings are usually made of steel. Steel is a very strong material that can withstand various loads. Sometimes, to protect against corrosion, steel rings are coated with special substances such as zinc or chromium.
Functions:
The retaining ring has a special shape that allows it to fit tightly against the part and the shaft. This creates a mechanical barrier that prevents the part from moving along the axis.
Applications:
Retaining rings are widely used in various industries:
- Mechanical engineering: For securing bearings, gears, couplings, and other parts.
- Automotive industry: For securing transmission parts, steering, and other components.
- Instrument making: For securing elements of precision instruments.
- Construction: For securing structural elements.
Advantages of using retaining rings:
- Reliability: Provides a secure fastening of parts.
- Durability: Made of durable materials.
- Ease of use: Easy to install.
- Versatility: Suitable for many types of connections.
Types of retaining rings:
There are several types of retaining rings that differ in shape and installation method:
- External: Installed in a groove on the shaft.
- Internal: Installed in a groove inside the hole.
- Split rings: Split rings that are easy to install and remove.
The external retaining ring DIN 7993 A is an important fastening element that ensures reliable securing of parts. Due to its characteristics and wide range of applications, retaining rings are widely used in various industries.
