Ball bearing blocks are used where the loads are more moderate and dynamic. The ball bearings provide for good sheave rotation with the lowest possible friction.
Features
Stainless steel ball bearing races, stainless steel ball bearings and glass fibre reinforced sheave for best bearing strength even under high dynamic loads
Acetal bearing cage to prevent ball-to-ball friction and to reduce weight
Composite, 50/50 glass fibre/polyamide
Maximum line size - 8mm Double and triple blocks come with a loop head.
