HUB & SPIDER DETAILS

HUB DETAILS

  • PUFLEX GS hubs are available in Aluminium and Steel Material.
  • PUFLEX GS sizes from 9 to 38 are made from Aluminium Alloy material.
  • PUFLEX GS sizes from 42 to 65 are made from Steel.
  • PUFLEX GS hubs are manufactured with high precision machining.
  • The jaws are machined with concave shape and entry chamfer for easy assembly.
  • The concave shape in jaws of hub and the convex shape on the polyurethane spider allows for better angular, parallel and axial misalignment.
  • These hubs are available in un-bored, pilot bored, finish bore & key-ways, and with different styles of clamping arrangements as per customer requirements.

SPIDER DETAILS

  • PUFLEX GS spiders are manufactured from high grade polyurethane.
  • PUFLEX GS are available in three different hardness as 80 Shore A, 92 Shore A, and 98 Shore A. This different hardness’s are made available to suit different applications.

The details are as below.

 

Spider Type
Shore Hardness
Colour Material Temperature Range ° C  Available sizes Application
Normal working Maximum
80 Shore A Blue Polyurethane from -50 to + 80 from -60 to + 120 PUFlex 5 to 24 Low torque, more mis-alignment
92 Shore A Yellow Polyurethane from -40 to + 90 from -50 to + 120 PUFlex 5 to 55 Medium torque, medium mis-alignment
98 Shore A Red Polyurethane from -30 to + 90 from -40 to + 120 PUFlex 5 to 65 More torque, less mis-alignment
