Side-Mount External Retaining Ring Assortments
![]() | ![]() C-Style Side Mount |
![]() E-Style Side Mount |
Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface. All are magnetic.
Black-phosphate steel retaining rings resist corrosion in dry environments.
Zinc yellow-chromate plated steel retaining rings resist corrosion in wet environments.
15-7 PH stainless steel retaining rings are chemical resistant.

Side-Mount External Retaining Rings

Also known as E-style rings, these rings have three prongs that make contact with the shaft and provide a wider shoulder than other external rings for a larger retaining surface. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. Ring OD is measured with the ring uninstalled.
1060-1090 spring steel and spring steel rings are an economical choice with good strength. A black-phosphate finish is mildly corrosion resistant in dry environments. In wet environments, a zinc yellow-chromate plated finish has some corrosion resistance, and a zinc-chromate plated finish has good corrosion resistance.
DIN 1.4122 stainless steel rings withstand wear caused by abrasion, similar to 400 series stainless steel. Rings are passivated for added protection against corrosion.
15-7 PH stainless steel rings have high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.
Beryllium copper rings conduct electricity and have excellent corrosion resistance. Do not use beryllium copper rings in direct contact with acetylene.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Heavy Duty Side-Mount External Retaining Rings

Also known as reinforced E-style rings, these rings are reinforced to withstand faster rotation than other side-mount retaining rings. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. They fit in the same grooves as standard E-style rings. Ring OD is measured with the ring uninstalled.
1060-1090 spring steel is an economical choice with good strength. Rings with a black-phosphate finish are mildly corrosion resistant in dry environments. Rings with a zinc yellow-chromate plated finish have some corrosion resistance in wet environments.
15-7 PH stainless steel rings are high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.
Beryllium copper rings conduct electricity and have excellent corrosion resistance. Do not use beryllium copper rings in direct contact with acetylene.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Wide-Grip Side-Mount External Retaining Rings

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. Ring OD is measured with the ring uninstalled.
1060-1090 spring steel rings are an economical choice with good strength. The black-phosphate finish resists rust.
15-7 PH stainless steel rings are high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.
