RETAINING RINGS

External E Ring

The most popular and widely used radial retaining ring is the "E"(so named because it is shaped like the letter "E"). The three prongs make contact with the bottom of the groove and provide a shoulder for effective retention of assemblies.

External Type SH

SH stands for "shaft" ring since it is applied externally onto a shaft.

 

Internal Type HO

HO stands for "Housing " ring since it is applied internally into a housing or bore.

Self Locking Internal/External Metric

This ring features an outer rim with a series of prongs protruding into the center. the ends create interference with the shaft when the ring is installed and load introduced to the other side. the difference between these two rings is that the outer rim of the TX is curved while the rim of the TY is flat. the curved rim of the TX affords greater thrust load capacity than the TY and is easier to orient for assembly.
