Locking Elements for Bearings (Nuts, Rings, Cotter Pins)

Locking elements for bearings ensure proper positioning of bearings on shafts or in housings and prevent unwanted movement during operation. They include locknuts, retaining rings, and cotter pins, which are essential components of every bearing assembly.

Locknuts are used for axial fixation of bearings on a shaft and are often combined with locking washers to prevent loosening. Retaining rings secure bearings in the axial direction, while cotter pins provide a simple and proven method of preventing rotation or axial displacement.

• Locknuts – axial fastening of bearings on shafts
• Retaining rings – secure axial positioning of bearings
• Cotter pins – mechanical safety against loosening

With these components, bearing assemblies are safe, precise, and reliable. Choosing the correct locking elements increases bearing service life, enhances operational safety, and reduces the risk of failures. These small but crucial parts are widely used across industries such as mechanical engineering, automotive, and agricultural machinery.
