Internal Circlips


Description:

Internal circlips from ITA Fasteners are retaining rings used for securing mechanical elements or bearings in bores and other rotating assemblies. They are mostly used in applications in which a centrifugal force is applied along the assembly's axis. The circlips are inserted into grooves and are used to create a shoulder to retain the assembly. To quickly install or remove the circlips, lugs with holes have to be used.

They are made with stainless steel, carbon steel, or alloy steel making them extremely corrosion resistant and durable. Therefore, they can be used in high strength applications and extreme heat and cold conditions without them losing their electrical or mechanical properties. These fasteners have been designed to maintain an equal width throughout their body and hence, can be seen flattened on the open ends. At ITA Fasteners, we undertake customised orders of any size and can promptly deliver the same.
