Regal Rexnord
Industrial Couplings
Regal Rexnord industrial couplings represent the most extensive and diversified coupling portfolio in the power transmission industry — encompassing gear couplings, grid couplings, jaw couplings, elastomeric couplings, disc couplings, universal joints, fluid couplings, barrel couplings, and fully engineered custom solutions. Brands such as Kop-Flex, Ameridrive, Bibby Turboflex, Euroflex, CENTA, TB Wood's, and Jaure deliver torque from fractional inch-pounds to over 100 million inch-pounds, connecting shafts across pumps, compressors, generators, marine propulsion lines, rolling mills, crushers, and cooling towers. Each coupling type is optimized for specific performance parameters: disc couplings provide the highest speed and temperature capability with zero maintenance; elastomeric tire couplings absorb shock and damp vibration while accommodating 4° of angular misalignment; gear couplings transmit maximum torque in minimum diameter packages; fluid couplings provide controlled soft-start torque limiting for conveyors and crushers. Regal Rexnord application engineers conduct torsional vibration analysis and alignment studies to ensure the coupling specified for a given drivetrain delivers rated service life under actual operating conditions.

Unmatched Portfolio Breadth
Choose from gear, grid, jaw, elastomer, disc, tire, fluid, barrel, and universal joint couplings — the widest selection available from any single manufacturer, simplifying procurement and engineering specification.
Torsional Vibration Analysis & Application Engineering
Engineers perform dynamic analysis to identify resonant frequencies and recommend couplings that avoid fatigue failure, extending drivetrain component life across motor, gearbox, and driven equipment.
High-Speed, High-Temperature Disc Couplings
Lubrication-free metallic disc designs operate reliably at speeds exceeding 30,000 rpm and temperatures beyond 400°F, suited for turbine, compressor, and test-stand applications.
Misalignment Accommodation & Vibration Damping
Elastomeric and grid couplings tolerate substantial parallel, angular, and axial shaft misalignment while reducing transmitted vibration, protecting bearings and seals from premature degradation.
Made-to-Order & Engineered-to-Order Capability
Custom bore configurations, special materials (17-4PH stainless, titanium, duplex alloys), and non-standard spacer lengths ship within aggressive lead times, accelerating MRO recovery and OEM program launches.
Torque-Limiting Fluid Couplings
Hydrodynamic fill-controlled couplings provide soft-start ramp-up for high-inertia loads, protecting motors from stall and drivetrains from shock overload in mining and material handling applications.
Why Regal Rexnord Couplings Deliver Superior Drivetrain Reliability
Coupling failure is often the "canary in the coal mine" — an early indicator of deeper drivetrain problems such as excessive misalignment, unforeseen torsional vibration, or inadequate torque capacity. Regal Rexnord addresses this through a consultative engineering approach that starts with understanding the driven load profile, not just the motor nameplate data. Using proprietary sizing software and decades of accumulated field data, engineers identify the optimal coupling type, size, and material for each unique application. This prevents the costly cycle of trial-and-error coupling replacements that plague many industrial maintenance programs.
Industry Applications
Regal Rexnord couplings transmit power across every major industrial sector. Oil and gas pipeline pumps use Bibby Turboflex and Euroflex disc couplings. Marine propulsion systems deploy CENTA elastomeric couplings between prime movers and reduction gears. Metals mills run gear spindles and Ameridrive couplings on rolling mill drives. Aggregate crushers utilize fluid couplings for soft-start loading. Power generation plants install flexible couplings between turbines and generators. HVAC chiller plants rely on elastomeric jaw couplings for vibration isolation.
