Series 55 Orbit
$51.90 – $329.90
Ronstan’s Ball Bearing Series 55 Orbit Blocks desgined for maximum 10mm rope, boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options, including a Dyneema link attachment instead of metal components.
Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets.
(Please Note: *Fiddle Blocks, small fiddle sheave has a high load full contact bearing (i.e. not ball bearing). Main sheave has 2-stage, ball bearing.)
