Seeger circlip rings, Seeger retaining rings, rings for shafts, Seeger rings, lock rings, snap rings

GUFERO Seeger circlip rings (also known as Seeger retaining rings) serve for the securing of stubs and shafts against motion along the axis and for the securing of machinery components in bores or for the securing of shafts. Seeger circlip rings are the simplest and also the most cost effective alternative to securing stubs against axial movement.

GUFERO retaining rings are manufactured from elastic steel and therefore do not lose their elasticity after being placed in the groove. The cross section of the retaining ring is largest in the middle and its radial width reduces towards the ends. If the Seeger circlip ring is bent it acts as a beam with the same strength and therefore the forces acting along the entire circumference of the circlip are equal. Under any deformation the retaining ring keeps its precise circular shape due to its high flexibility. External Seeger circlip rings are countersunk in the groove in the stub or the shaft.

Seeger circlip rings for bores

This type of Seeger rings are designed for the securing of shafts. The production standard applicable to the manufacture of the Seeger rings is DIN 471. The dimensions of the Seeger retaining ring are given by the diameter of the shaft. It is therefore not possible to determine the dimension of the Seeger retaining ring itself before measuring the shaft. It is possible to determine the dimension of the shaft for which the Seeger rings are intended by measuring the internal edge of the Seeger ring with the opposite external edge. The obtained dimension of the shaft for the Seeger ring is an approximation only. A Seeger retaining ring is applied using Seeger pliers. It is necessary to extend the Seeger ring and to pull it over the shaft and click the retaining ring into the groove in the shaft. The flexibility of the Seeger retaining ring ensures its compression in the groove which thereby secures the shaft itself or its rotating counterpart against movement over the Seeger retaining ring.

Seeger circlip rings for bores

Seeger rings for bores are designed to secure components against movement in cylindrical cavities of machine components. Seeger rings of this type are manufactured pursuant to the DIN 472. The dimension of the Seeger ring cannot be determined precisely from the size of the ring. As before, the approximate dimensions of the Seeger circlip can be determined by measuring the distance between the internal edge of the Seeger ring and its opposite external edge. The Seeger ring is applied into the bore using Seeger pliers. The Seeger ring must be compressed using Seeger pliers to rove the retaining ring through the bore. After the Seeger retaining ring is placed in the groove, it extends and secures its position against the bore.

E-rings

E-rings are used for belt pulleys and stubs with small diameters. Their manufacture is dictated by the DIN 6799 standard. Unlike Seeger circlip rings for shafts and Seeger circlip rings for bores, no Seeger pliers are required for the application of the E-ring type retaining ring. The E-ring is open on one side. This V-shape opening allows considerably easier installation of the E-ring. The retaining ring is applied onto the edge of the groove and by pressing the opposite side of the E-ring, the retaining ring clicks into the right position.
