Suffix "R" designates high speed ring design. Rings are furnished standard for sizes ES2-R to ES10-R, optional for sizes ES20 to ES80.
With shallow keyway. *With extended bore bushings.
Service factor = 1.0. This rating may be lower if limited by the bushing rating, particularly if severe service conditions exist.
Consult bushing manufacturer.
Spacer couplings furnished with optional high speed rings (sizes ES20 to ES80) can be operated up to maximum allowable speeds for standard series couplings.
Minimum shaft spacing is 0.25 inch. See page E-8 for additional information.
Without compression bushings.
