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.Head posts of swivel
blocks can be locked at 0 or 90 degrees.
