Selden 100mm Single Swivel Block with Becket
A plain bearing block handling up to 4 ton load.
The block features a plain bearing with acetal bushing and two axial Delrin® bearings. These stabilize the sheave when the rope enters or exits the block with an angle.
Machined, black anodised aluminium sheave and cheeks.
The swivel pin is hollow and chamfered to reduce weight and all stainless parts are insulated from aluminium to prevent corrosion.
The blocks are quick and easy to dismantle for maintenance.
