Description 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). Fixed Hook – A built-in hook to make attachment quick and easy. The hook can articulate, so it’s ideal for outhaul and cunningham systems.
