Seldén blocks give you the benefits of a high strength to weight ratio. Seldén only use top quality materials like composite, 50/50 glass fibre/polyamide and marine grade stainless steel. Each component is designed for top performance and perfect interaction with the rig under all conditions. The bearing cage design of the ball bearing blocks is a typical example of functional Seldén design. It not only lowers block weight, but also further reduces friction.
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.
