Internal Retaining Rings

Internal Retaining Ring

Also known as:  

Housing Rings

Internal Retaining Rings are compressed to fit inside a housing or bore using the ring's lug holes and retaining ring pliers (see separate listing). When the pressure is released, the rings expand and lock into a machined groove. Internal Retaining Rings can accommodate high thrust loadings and provide a large protruding shoulder to retain components and assemblies. Ring size refers to housing diameter, which is smaller than the ring's free diameter. See our Internal Retaining Ring Specifications reference charts.
