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.
Features through-hub mounting for maximum strength and can be stacked to create a double (total block load same as single, maximum load on top sheave not to exceed 50% of total block load).Cover plate can be removed for service access without removing tApplications
