20mm Plain Bearing Blocks

20mm Plain Bearing Cheek Block.This block is mounted to our Profix cheek adapter which allows for articulation, so the block can lift up and down to align correctly with the rope. Ideal for leading lines along a deck, into a cleat or around corners. Held in place by one screw through the head of the Profix cheek adaptor.  The A2020P is our block of choice for applications which require a lightweight, budget friendly pulley. Plain bearing blocks are the ideal choice for take up systems or systems which do not require friction reduction. For ultimate performance, we suggest using the Dynamic block range instead. This plain bearing block is made from recycled plastics. Plain Bearing – The acetal sheave spins around the central axle. This type of bearing has a long lifespan and is very low maintenance. Becket – The hole through the middle of the block can be used as a tying off point (becket).
