Stainless Steel Discs in Factory-assembled Cartridge for High-torque Applications (Metric)

TLK coupling range is particularly suited for high-torque electric motor or turbine drives in critical process industry, marine and power generation. Torque is transmitted through two sets of membranes, separated by a spacer element, and protected by two adaptable guard rings in a pre-assembled transmission unit. The coupling provides a good level of angular, lateral and axial misalignment, while maintaining a high level of balance integrity. Standard options for spark resistance, electrical insulation, limited end float and torque limiting are available. The TLK utilizes all metric fasteners.

  • California Residents: PROPOSITION 65 WARNING
  • Flexible solution for high torque and misalignment.
  • Meets API 610 (ISO 13709). Can be supplied to meet API 671 (ISO10441).
  • Intrinsic balance meets AGMA class 9.
  • Excellent power-to-weight ratio.
  • High misalignment capability.
  • Low imposed forces on machinery leading to reduced machinery vibration and maximized bearing life.
  • Stainless steel flexible membranes for maximum life.
  • Cartridge transmission unit eases assembly and gives repeatable balance.
  • Overload collars are fitted to protect the flexible membranes in case of severe torsional overload, with an option in spark-resistant materials.
  • Anti-fly retention of the spacer in the unlikely event of membrane failure.
  • Puller holes incorporated into hubs as standard.
  • Unique modular design allows correctly rated coupling to be installed, even on large diameter shafts.
  • Special thread form ensures hub bolts have all-metal, self-locking feature for security. This allows the bolts to be used repeatedly without compromising their integrity.
