30mm Single eco block with swivel head.  This modern range of plain bearing blocks is manufactured using 100% recycled plastics and 20% less material than their predecessor. Utilising other high load components from the Allen Dynamic range makes them high strength and efficient to produce, helping to reduce the long-term impact of plastics and un-recyclable materials on the environment. The grey sheave distinguishes them from the black sheave Dynamic range. Plain bearing blocks offer great static loading capabilities at a low weight and cost, making them perfect for take-up systems or applications that don't require high dynamic performance.   Part Description Lengthmm Line Dia.mm.
