Busan specialist in disc, gear, grid and elastomeric shaft couplings

LISTEDMANUFACTURER Busan, South Korea

About

JAC Coupling is a Busan manufacturer that makes only power-transmission couplings, covering disc, gear, grid, tire, jaw, rubber, elastomeric, muff, wire-drum, brake-drum and composite types.

The company states it has about two decades of coupling experience and machines its products on in-house high-accuracy equipment. Its range runs from small micro couplings for encoders and servo motors up to large gear couplings rated above 300,000 kgf·m and couplings for multi-megawatt wind turbines.

Products are aimed at steel works, cranes, pumps, compressors, conveyors and general machinery, with spacer and brake-drum variants for crane and mill drives.

Disc Couplings

Laminated steel disc couplings with no sliding parts, giving zero backlash and no lubrication. A standard A/E/G-type range covers small machine-tool and servo drives, while two large series serve pumps, compressors and turbines.

Key features

  • No lubrication, no wear parts
  • Zero backlash and high torsional stiffness
  • Standard, spacer and floating-shaft arrangements (A/E/G, A4, AX)
  • Large 00 and 01 series up to 10,530 kgf·m
  • Allowable end float published for large sizes

Applications

  • Machine tools and indexing tables
  • Pumps and compressors
  • Printing and paper machinery
  • Turbine and generator drives
  • 3.4–10,530 kgf·m, bores to 254 mm
