AFTERMARKET New block range from Allen 26/06/2023 Save article Allen has launched a new 40mm dynamic block range. SHOW FULLSCREEN Allen’s 40mm dynamic block range is available in 29 variations The blocks are available in 29 variations, manufactured from high-strength, lightweight glass-loaded nylon incorporating Allen’s dynamic bearing technology. Development has taken place over the last two years with a focus on the high-performance keelboat and dinghy market with new variations for different systems. The blocks have stainless-steel ball bearings which Allen says roll more quickly and last longer when subjected to high working loads compared to plastic alternatives. The blocks also have a stainless-steel rail for the balls to roll on for further friction reduction and improved reliability and performance over a longer period. “To further reduce friction, we have encapsulated the ball bearings in a cage, this stops each of the bearings from rubbing against each other,” said an Allen spokesperson. “The reduced friction in caged ball bearings leads to improved performance. “With less friction, the bearings can operate more efficiently, requiring less energy to rotate. This results in smoother operation, reduced wear, and improved overall performance of the block.” Other features include a lockable swivel shackle attachment which can be locked in 90-degree orientations. Alternatively, the shackle lock can be removed for the block to rotate freely. Single, double and triple sheave options are available with aluminium ball-bearing cam cleats mounted via an adjustable arm which can be adjusted to suit different sheeting angles.
