What are snap rings?
A snap ring is a special form of locking ring. In mechanical engineering, it secures components such as wheels, sealing elements and bearings on axles, shafts or within bores against axial displacement with a positive fit.
Why is he called that? The name snap ring is derived from the earlier production method: at that time it was cut from pipes and then ripped open. Today snap rings are made of spring steel wire with a constant cross-section. They are bent into a ring on a winding machine. The diameter can be a few millimeters to a few meters.
What are the advantages?
Snap rings absorb the forces that act in the direction of an axis of the rotating body. The securing element fixes the respective component and prevents it from shifting axially in the bearing seats. Snap rings are versatile and offer the best and most cost-effective solution in many different cases.
Offer snap rings
Snap rings are available in two basic designs: for shaft construction and for bores. A special DIN variant is available for every application.
Snap rings DIN 7993 for shafts
In order to place a snap ring on a shaft, it is notched at an appropriate point and a groove is inserted. This is about 0.1 to 0.2 mm wider than the ring itself. To avoid deformation of the shaft locking ring, a conical assembly mandrel can also be placed on the shaft end or a thin-walled sleeve can be slipped over the shaft. The widened ring is pushed over the shaft by means of a pair of pliers.
Gutekunst Federn offers snap rings for shaft diameters from 4 to 125 mm in the spring materials normal steel EN 10270-1 and stainless steel EN 10270-3-1.4310 from stock. Here you can find the article selection snap rings for shafts
Snap rings DIN 7993 for bores
With a bore, the snap ring is installed in a similar way to a shaft, only the notch is usually deeper. Conical sleeves simplify the assembly of the bore retaining rings. The rings are also inserted into the hole with a pair of disintegrating pliers. When installing in gearboxes, the snap rings can also be used as spacers.
Gutekunst Federn offers snap rings for bore diameters from 7 to 125 mm in the spring materials normal steel EN 10270-1 and stainless steel EN 10270-3-1.4310 from stock. Here you can find the article selection snap rings for bores
particularities
Snap rings made from round wire can also be used as spring rings to secure screws. Since the ends of the spring ring are not aligned with one another, they generate an axial force during the radial tightening movement. If vibrations occur, the screw connection is firmly protected and cannot loosen by itself. In this way, for example, railroad tracks are secured.
Individual snap rings
Next to the Catalog program on snap rings for shaft and bore locking, Gutekunst Federn also develops and produces snap rings according to your individual specifications, which can be optimally adapted to your needs.
