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. Available in 20, 30 and 40 mm sheave diameters.
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
