Axially Assembled
Axial retaining rings are designed for axial installation into machined grooves. These rings are either internal for installation in housings and bores, or external, for assembly on shafts. Once installed, they provide a protrusion or “shoulder” for retaining parts.
Technical Resources
HO – Internal Housing Ring
Once installed in the groove of a housing/bore, the portion of the ring protruding from the groove (also called a “shoulder”) holds an assembly in place.
SH – External Shaft Ring
Once installed in the groove of a shaft, the portion of the ring protruding from the groove (also called a “shoulder”) holds an assembly in place.
HOI – Internal Housing Inverted Ring
Functions like an HO ring in a housing/bore, only the lugs are “reversed.” This version reduces the distance the lugs of the standard HO extend into the inner circumference of the housing/bore and allows for another assembly to pass through unimpeded.
SHI – External Shaft Inverted Ring
Functions like an SH ring on a shaft, only the lugs are “reversed.” This version reduces the distance the lugs of the standard SH extend beyond the circumference of the shaft. The shaft can then be used in an application where clearance in minimal.
SHR – External Shaft Reinforced Ring
The SHR is an extra thick version of a regular SH retaining ring. As such, it is stronger and can withstand greater thrust loads than its standard counterpart.
SHM – External Shaft Tamper-Proof Ring
The SHM also functions like an SH retaining ring, but in “smaller” applications. It is also a tamper proof ring which does not have any lugs and can not be easily removed once installed.
