Thomas SR71 and SR718 Disc Couplings
Thomas disc coupling platforms within Regal Rexnord — SR71 and SR718 families for pumps, compressors and industrial drives requiring flexible disc pack torque transmission. Family-level engineering discovery; designation-level catalogue data not yet verified in repository.
Thomas disc coupling families
Thomas disc couplings within the Regal Rexnord portfolio use flexible disc packs to transmit torque while accommodating misalignment. SR71 and SR718 represent platform families within the Thomas disc coupling line for industrial motor-driven equipment.
Golden Bearing Company maintains a single canonical family page for both SR71 and SR718 intent — separate Rexnord reference URLs for each platform do not require duplicate pages on Golden Bearing Company.
Disc coupling principles
Multiple thin discs flex to absorb misalignment without sliding contact in the element. Assemblies may be close-coupled or use spacer tubes for pump and compressor maintenance. Hardware, disc pack and hub designs are series-specific.
SR71 and SR718 platforms
SR71 and SR718 denote distinct Thomas disc coupling platforms with different size ranges and configuration options. Identification requires installed marking, bore measurement and application duty review. No verified designation-level catalogue data is published on Golden Bearing Company in this batch.
Applications
Disc couplings are common on pumps, compressors, blowers, gearboxes and test equipment where precise torque transmission and defined misalignment capacity are required. Environmental factors and cyclic duty influence disc pack selection.

Send manufacturer part numbers, bore sizes or coupling designations for engineering identification and quotation support. This is an identification/interchange enquiry—not a live stock lookup or availability confirmation.
Common questions
SR71 and SR718 denote distinct Thomas disc coupling platforms within the Rexnord catalogue, with different size ranges and configuration options. Confirm the installed marking or send photographs for identification support.
Disc couplings are generally non-lubricated flexible couplings. Maintenance focuses on disc pack inspection, bolt torque and alignment per manufacturer guidance.
Verified designation-level technical data for Thomas SR71 and SR718 is not yet established in the governed repository. This family page provides engineering discovery and enquiry support until verified data is ingested.
