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 Acetal 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.
ApplicationsPrimary mainsheet, halyard and spinnaker systems on boats to 14 m (46 ft)
Secondary mainsheet, vang blocks on boats to 15 m (50 ft)
Standard and running backstay systems on boats to 12 m (40 ft)
General control line and lead block applications on larger yachts
Materials
Fully machined Alloy cheek plates
Alloy sheaves with captive ball races
Torlon° needle rollers
Carbon black Acetal ball bearings
