THE PUNK® FAILSAFE FAMILY

Utilising either Mohicans or axles as the primary torque path, the Punk® Failsafe is a single coupling that can be adapted to provide performance broadly similar to the equivalent Punk® Prime or Gim-Ball.

The coupling will remain operational in the presence of multiple element failures, making them ideal for high integrity drivetrains where reliability is key.

Various sealing options available, including our novel seal cap design All standard shaft interfaces can be accommodated; including key, spline, flange, tapered lock and clamp types Can be concentrically supported, producing a multi-functional coupling and support bearing

IDEAL APPLICATIONS

  • Where ‘Waiting-failsafe’ functionality is required
  • Adaptable to Punk® Prime or Punk® Gim-Ball applications

THE

PUNK® FAILSAFE EXTENDED

The Punk® Failsafe Extended is the Punk equivalent of a Flex-Rigid type gear coupling or universal joint and has inherent damage tolerance and waiting-failsafe torque paths.

It features an integral hub extension on the outer ring, which can house a range of shaft interface types and sizes. For many applications, the input and output interfaces would be the same (e.g. keys), to couple shafts of similar dimensions.

  • Various sealing options available, including our novel seal cap design.
  • All standard shaft interfaces can be accommodated; including key, spline, flange, tapered lock and clamp types
  • Can be concentrically supported, producing a multi-functional coupling and support bearing

PUNK® FAILSAFE DOUBLE SERIES

The Punk® Failsafe Double Series is our equivalent of the double Cardan shaft or Flex-Flex type gear coupling.

Two Punk® Failsafes are housed in a sleeve, creating a coupling that caters for both angular and parallel misalignments. The shaft interfaces are internalised giving much lower Distance Between Shaft Ends (DBSE) than achievable with an equivalent Cardan shaft, thereby reducing the footprint of your machinery.

  • The outer rings can be integral with, or mechanically fastened to, the sleeve
  • Alternative designs connect the inner rings together with a small diameter solid shaft
  • Split coupling options are available, using flanges
  • The sleeves and shafts can be floating or fixed (axially)
  • Various sealing options available, including our novel seal cap design
  • All standard shaft interfaces can be accommodated; including key, spline, flange, tapered lock and clamp types
  • Can be concentrically supported, producing a multi-functional coupling and support bearing
