Hardy Couplings

Hardy Couplings zoom [+]

Are mainly designed for flexible connection of engine shafts and powered machines, for example pumps. Hardy couplings are mainly cylindrical, occasionally star shaped or oval.

In general:

Usage:

Hardy couplings are mainly designed for flexible connection of engine shafts and powered machines. They prevent the transfer of impacts during startup and take care of the possible minor misalignment of the axis of the driven shaft and the driveshaft.
For general usage, we manufacture the Hardy couplings in dimensions from a diameter of 60 mm and height of 15mm (at least 5 mm) all the way up to a diameter of 390 mm (maximum 700 mm) and height of 45 mm (to 60 mm). For especially stressed couplings, we manufacture high-strength Hardy couplings; their structure allows a greater load. The openings into the Hardy couplings can be fitted with sheet metal reinforcement knobs or steel tubes. From our experience with the high-strength Hardy couplings, we do not recommend reinforcing the openings. For small dimensions of hardy couplings it is only possible to reinforce with tubes.
Technical essentials of the order

  • identification by name of the Hardy coupling, supplemented with the design type (high-strength)
  • dimension (outer diameter, thickness, or possibly the inner diameter)
  • amount of openings and their diameter
  • hole circle of the openings
  • request for possible reinforcement with knobs (diameters of 8,10,12,14,16,18,20 and 22 mm)
  • request for possible reinforcement with tubes (cannot be combined with knobs!)
  • use the catalogue number

Material

High-strength Hardy couplings contain polyamide fibre netting; classic Hardy couplings are made of rubber textile composites.
