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.

• Stainless steel strap to ensure high strength and stiff sides.
• Stainless steel ball bearing races and glass fibre reinforced sheave for best bearing strength even under high dynamic loads.
• Glass fibre reinforced polyamide composite.
