Ronstan Orbit Series 55 Ball Bearing Blocks

Ball Bearing Orbit Blocks™ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneema® rope link head.

Their precision design allows the optimum number of ball bearings in loaded areas and eliminates them in inactive areas. Ineffective mass is reduced even further through fibre-reinforced composites in the block head, cleat arms and beckets.
