Description The acetal sheave spins around the central axle. This type of bearing has a long lifespan and is very low maintenance. A plain bearing block, using 100% recycled plastics as well as using 20% less material than the previous Allen versions. Using the outer cheek and strap from the 20 and 30mm dynamic range allows Allen to manufacture the new range of plain bearing blocks more efficiently. This will help to reduce the long-term impact of plastics and un-recyclable materials on the environment. The new range of plain bearing blocks will also feature a grey sheave to differentiate them from the existing dynamic range, which has black sheaves. Plain bearing blocks offer great static loading capabilities at a low weight and cost. This makes them perfect for take-up systems or applications that do not require high dynamic performance. Sheave diameter – 20mm Maximum line diameter – 6mm Breaking load – 540kg weight – 10g length – 37mm
