![]() ![]() The same thing happens when a beveled retaining ring is installed into an application. The cork is forced into the opening until it is wedged as far into the opening as possible. This angle allows the ring to wedge itself between the groove and the retained part until it can go no farther, effectively “locking” everything in place. Inverting the lugs allows greater clearance on a shaft or in a housing and forms a higher uniform shoulder good for retaining bearings and other components with large corner radii or chamfers.īeveled retaining rings feature a 15° beveled or angled edge. Inverted retaining rings are a variation of axially assembled rings in which the lug holes are inverted to fit in the bottom of the groove. These rings are manufactured with lug holes-small holes in the lugs of both axial internal and external retaining rings-that are used to install/remove them, using pliers designed for this purpose. ![]() For larger rings: wire forming, in which rectangular wire is coiled into the shape of the ring.Īxially assembled Pliers for installing and removing retaining ringsĪxially assembled retaining rings are installed into machined grooves in housings/bores (internal) or on shafts (external).For smaller rings: using a die and stamping on a press from a coil of steel or copper.Depending on the size of the ring in question, it may be manufactured in one of two ways: These rings may be installed axially (horizontally along the center point of an axis) or radially (externally along the radius of a circle). This assures contact with the groove along the entire periphery of the ring. Tapered section retaining rings decrease symmetrically from the center to the free ends, remaining circular when contracted or expanded within the limits of normal use. Tapered section retaining rings Axially installed retaining rings There are four main types of retaining rings available, each of which may then be broken down into sub-types depending on unique application needs: Retaining rings are typically made from carbon steel, stainless steel or beryllium copper and may feature a variety of finishes for aesthetics and corrosion protection depending on the type of environment in which they are used. Circlips are a type of retaining ring.Ĭircular push-on retaining rings may be installed in applications where there is no groove. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. JSTOR ( August 2018) ( Learn how and when to remove this template message)Ī retaining ring is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed - typically in a groove - for one time use only.Unsourced material may be challenged and removed. Please help improve this article by adding citations to reliable sources. Light-weight two-hand circlip pliers help to move the rings to the right place with little effort and with the help of a special locking mechanism.This article needs additional citations for verification. Speaking of large: With circlips over 140 mm in diameter, the actuating forces for one-hand pliers are too great. As the thin working tips are sensitive to overloading, the largest possible pliers for the existing ring should always be used. In order to give you the best possible orientation, the permissible ring diameters are printed on all circlip pliers from KNIPEX. When dealing with circlips, one thing must be noted: The size of the ring and the size of the circlip pliers must always be coordinated. You see: No matter which pliers are required when installing or removing circlips: With 80 different circlip pliers, KNIPEX always has an answer! For retaining rings with straight flanks in the separating slot, we again offer special pliers with a corrugated, non-slip outer surface that ensure that you have the expansion of the external ring under control at all times. With the help of this hole, the tips can be gripped safely and the ring can be moved to the intended location. The special feature of retaining ring pliers: a narrow surface with a centered hole. Retaining rings are a slim design version of circlips - they taper at the opening and are gripped there. ![]() Last but not least, retaining ring pliers complete the range of circlip pliers from KNIPEX. The first choice for working with grip rings should be our circlip pliers for grip rings. These hold onto the shaft with pure gripping force and are therefore assembled or disassembled with a modified form of circlip pliers for external rings. There are special forms of circlips on the market. ![]()
