Description
The EP-SWC Series is Ever Power’s complete cardan shaft flange coupling range — encompassing all SWC and SWP variants under one engineering and quality umbrella. Welding-type and flange-type, standard flex / long flex / short flex / without flex, single-joint and double-joint configurations covering gyration diameters from 58 mm to 1,000 mm and torque ratings from 0.16 kN·m to 2,500 kN·m. ISO 9001 quality management, 35CrMo alloy steel construction, and a 20-year manufacturing track record back every coupling in the range.
EP-SWC Series Specifications and Dimensional Range
The EP-SWC Series quality and specification standards apply uniformly across the full range. Material specification, heat treatment processes, bearing selection, sealing arrangements, and quality documentation are consistent regardless of which specific variant (BH, CH, DH, BF, WH, WD, WF, or any SWP variant) is supplied. The table below summarises the range envelope.
| Model | Gyration Ø D (mm) | Nominal Torque Tn (kN·m) | Fatigue Tn Tf (kN·m) | Flex Angle β (°) | Bore D₂ (mm) | Lmin (mm) |
|---|---|---|---|---|---|---|
| Gyration Diameter Range | 58 mm to 1,000 mm | Torque Range | 0.16 to 2,500 kN·m | Speed Range | Application-dependent | |
| Welding Type Variants | BH / CH / DH / WH | Flange Type Variants | BF / WD / WF / All SWP | Hub Connection | Welded or Bolted | |
| Standard Flex Variants | BH / BF / SWP-A / SWP-B / SWP-E | Without Flex Variants | WH / WD / WF / SWP-C / SWP-D | Flex Angle Range | Up to 90° per joint | |
| Material | 35CrMo alloy steel | Surface Hardness | HRC 58-64 (induction) | Heat Treatment | Quench-and-temper | |

What Distinguishes the EP-SWC Series from Other Universal Joint Types
The EP-SWC Series umbrella exists because cardan shaft selection involves many variant choices — welding versus flanged hub connection, flex versus without-flex intermediate construction, standard versus long versus short flex length, single versus double joint geometry. Most application engineering work starts with the load and geometry parameters, then selects the variant combination matching those requirements. Our Sydney team supports this selection process across the full range.
Beyond the standard SWC and SWP variants, the EP-SWC Series also encompasses custom configurations developed for specific Australian industrial applications — custom intermediate shaft lengths for retrofit projects, non-standard flange interfaces matching legacy OEM equipment, marine-grade specifications for vessel propulsion drivelines, and agricultural-grade specifications for harsh field-service environments. The range envelope is broad enough to cover essentially any heavy industrial cardan shaft requirement across Australia.
Quality Management and Documentation Standards
Every EP-SWC Series coupling is manufactured under the same ISO 9001 quality management system, with material traceability, dimensional inspection, and heat treatment certification available on request. The standard quality documentation pack includes material certificates, dimensional inspection report, and heat treatment certificate. Additional documentation including witness inspection, non-destructive testing reports, and classification society approvals is available where the application requires.

Industrial Applications Across Heavy Industry
EP-SWC Series applications span the full Australian heavy industrial application envelope — rolling mills, cranes, mining equipment, marine propulsion, agricultural machinery, construction equipment, and process industry drives. The range envelope is broad enough that the application engineering question is variant selection rather than capability.
Steel and Metallurgy Industry Applications
Hot and cold rolling mill main drive spindles, slab and bloom transfer car drives, coiler and uncoiler drives, and finishing mill stand spindles all use EP-SWC Series cardan shafts. Variant selection depends on the specific shaft-centre distance, operating angle, and connection method — our Sydney engineering team handles the variant selection from the application parameters.
Marine, Mining, Agricultural, and Process Industry
Commercial vessel propulsion drivelines specify EP-SWC Series cardan shafts in flange-type without-flex configurations. Mining equipment articulated drivelines use double-joint variants. Agricultural PTO drives specify long-flex double-flange variants. Industrial pump and conveyor drives use single-joint flange-type variants. The complete EP-SWC Series range covers all these application categories with appropriate variant selection.

Selecting the Correct EP-SWC Series Size for Your Drive
Variant selection within the EP-SWC Series starts with the application parameters: nominal torque, service factor, gyration diameter envelope, operating angle range, shaft-centre distance and travel, connection method (welded or flanged), and operating environment. Our Sydney engineering team handles the variant selection — provide the application parameters and we recommend the appropriate variant with sizing justification.
For retrofit applications replacing worn OEM cardan shafts, provide the OEM model code or a dimensioned drawing. Cross-reference work for Voith Turbo, Rexnord, SKF, GKN, and other major OEM cardan shaft brands is included as a standard service across the EP-SWC Series.
Installation, Operation, and Maintenance Best Practice
Installation procedures vary by variant — welding-type variants require qualified field welding; flange-type variants bolt onto existing shaft flanges. Specific installation procedures are published on the dedicated product pages for each variant.
Confirm the specific variant supplied matches the application requirement. Review the supplied documentation pack including dimensional inspection certificate and installation procedure for the specific variant.
Inspect the coupling for shipping damage. Verify all rotational components rotate smoothly by hand. Verify dimensional compliance against the supplied drawing.
Welding-type variants: qualified field welding per supplied weld procedure specification. Flange-type variants: bolt-on installation with staged torque application and locking compound.
Verify operating angles, axial position, and parallel offset (for double-joint variants) are within the variant-specific rated envelope.
Run at progressively increasing speed through the full operating envelope. Monitor vibration and bearing temperature for first 50 hours.
Inspect bearings, seals, and bolt torque (or weld integrity for welded variants) at the first scheduled maintenance interval after commissioning.
OEM Cross-Reference and Order Specification
Cross-reference is available across the EP-SWC Series for Voith Turbo cardan shafts, Rexnord universal joint couplings, SKF industrial couplings, GKN industrial driveshafts, and other major OEM brands. Provide OEM model code, key dimensions, and connection method for direct equivalent confirmation.
Custom configurations matching legacy OEM equipment dimensions are available throughout the EP-SWC Series. Custom intermediate shaft lengths, non-standard flange interfaces, marine and agricultural specifications are all handled by our Sydney engineering team. Standard production lead times apply — typically 3 to 6 weeks for custom configurations.
