Lovejoy RRC280 Jaw Coupling Spacer Assembly 7 In
Lovejoy RRC280 radially-removable spacer assembly, 7″, includes 2 RRC jaw rings, collar with hardware, and SXB (NBR) cushions. For applications requiring shaft separation beyond standard jaw coupling length, with tool-free radial removal for maintenance access.
When equipment shafts sit further apart than a standard jaw coupling can bridge, or when you need to service a pump or seal without pulling the whole drive, a radially-removable spacer coupling solves both problems at once. This RRC280 assembly bridges a 7″ gap and can be removed sideways for maintenance, without disturbing the connected shafts.

Who This Fits
This spacer assembly fits RRC280-size jaw couplings with a bore range from 1.250″ to 3.375″, rated to 854 in-lb nominal torque. It’s the right choice for pump, mixer, or gearbox installations where equipment spacing exceeds a standard coupling and where periodic maintenance access without full disassembly matters.
What to Check Before Buying
Confirm your hub bore falls within 1.250″-3.375″ and that your equipment spacing matches the 7″ spacer length, RRC spacer assemblies come in multiple lengths and aren’t interchangeable. The cushions included are SXB (NBR) compound; check this matches your application’s temperature and chemical exposure needs.
