Rings for End-Play Takeup
Rotor Clip bowed retaining rings are designed to compensate for accumulated tolerances in assemblies. Once snapped into the groove, bowed rings exert a force or “preload” on the retained parts made to the low side of the tolerances “snugging” everything up. They also act like a spring and “give” when parts made to the high side of the tolerances extend too far into the groove.
Technical Resources
BHO – Internal Bowed Housing Ring
Compensating for accumulated tolerances is what a BHO retaining ring is designed to do in a housing/bore. Once snapped into the groove, bowed rings exert a force or “preload” on the retained parts for the range specified on the BHO size range chart.
BSH – External Bowed Shaft Ring
Compensating for accumulated tolerances is what a BSH “bowed” retaining ring is designed to do on a shaft. Once snapped into the groove, bowed rings exert a force or “preload” on the retained parts for the range specified on the BSH size range chart.
VHO – Internal Beveled Housing Ring
These rings look exactly like their HO counterpart, only they have a 15° angle on the outer edge. This combines with a complementary groove angle to eliminate end play by wedging itself between the groove and the retained part.
VSH – External Beveled Shaft Ring
These rings look exactly like their SH counterpart, only they have a 15° angle on the inner edge. This combines with a complementary groove angle to eliminate end play by wedging itself between the groove and the retained part.
BE – External Bowed E Ring
Compensating for accumulated tolerances is what a BE “Bowed” retaining ring is designed to do on a shaft. Once snapped into the groove, bowed rings exert a force or a “preload” on the retained parts for the range specified on the BE size range chart.
EL – External Bowed Locking Ring
Another variation of a bowed E ring is the EL. In addition to the bowed design for eliminating “play” in an assembly, it also features two prongs, which extend from the inner circumference to the open end locking the ring firmly into place.
