Snap Ring Bearings

Snap rings bearing, also known as retaining rings or circlips, are a type of fastener commonly used to secure bearings and other components in place, particularly in automotive applications like transmissions and hub assemblies. Snap rings are metal rings with open ends that can be “snapped” into a groove to create a shoulder and prevent axial migration of components. They offer several advantages over other fasteners, including reduced weight, vibration, and the need for mechanical fasteners like nuts and pins. Snap rings can be installed either internally or externally and come in different types like tapered section, constant, spiral, and circular push-on. Bearings with snap rings are often denoted with the “NR” nomenclature, indicating the manufacturer’s standard for the snap ring configuration. Overall, snap ring bearings provide a versatile and cost-effective solution for securing components in place.
