RANGE INFORMATION

Orbit blocks are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Torlon® ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.


APPLICATIONS

  • Mainsheet and genoa sheet systems on boats to 28m (92ft)
  • Spinnaker systems, halyards on boats to 31m (102ft)
  • Running backstay systems on fractionally rigged boats to 23m (75ft) or 28m (92ft) masthead

MATERIALS

  • Fully machined Alloy cheek plates
  • Alloy sheaves with captive ball races
  • Torlon® needle rollers
  • Torlon® ball bearings
