What is DIN 472?

Circlip DIN 472 The internal metric circlip is made of carbon spring steel with phosphate & oil being the standard finishes. The DIN 472 internal metric circlip comes in a variety of dimensions to help match the dimensions, groove standards, weight, and more.

Is 3075 an internal circlip?

Internal Circlips has a large free diameter and gap width, consequently it fits more tightly into the groove and provides higher and more uniform thrust load capacity. Lugs with holes are provided for rapid fitting or removal with circlip pliers.

What is the difference between internal and external circlips?

Circlips come in two main types – internal and external. An external circlip is designed to fit around a bore, whereas internal circlips are made to fit inside a cylindrical shaft or housing.

What is the purpose of a circlip?

Circlips are small, semi-flexible metal rings. They are a type of fastener and are also known as C-clips, Seeger rings, snap rings or Jesus clips. They’re most commonly used in machine grooves, where their key job is to hold dowel pins securely in place.

How do you size an internal circlip?

Internal Circlips are always listed by the bore size they are fitting in to. For example, if you have a 20mm bore and need a Circlip for this application, you will require a 20mm Internal Circlip.

Why are circlips used?

Circlips are used to prevent lateral movement. They are used as retaining rings on bearing assemblies and are manufactured using semi-flexible metal ring. These products are in a shape of a circle with a clip and are open from one end. The most common form of axially fitted circlips for shafts with grooves.

What do snap rings do?

Retaining rings — also known as snap rings or circlips — are metal fasteners installed into a groove on a shaft, or in a housing or bore to retain an assembly. The devices keep parts in place using a compact, lightweight design that requires fewer machining operations than other fastening techniques.

Is 3075 external circlip?

External Circlip DIN 471/ IS 3075.

How do you measure an internal circlip?

Internal Circlips (DIN 472 / D1300) are always measured by the bore size the Circlip is fitting in to. For example if you need a Circlip to fit in to a 40mm bore, you will need to purchase a 40mm Internal Circlip.

How are circlips measured?

External Circlips (DIN 471 / D1400) are always measured by the shaft size the Circlip is fitting on to. For example, if you need a Circlip to fit a 40mm shaft, you will need to purchase a 40mm External Circlip. Internal Circlips (DIN 472 / D1300) are always measured by the bore size the Circlip is fitting in to.

How much weight can a circlip hold?

A self-locking retaining ring, which does not need a groove, provides 66 lbs. of static thrust load capacity; an external retaining ring for the same application installed in a soft groove provides 1,200 lbs.
