The self-contained alloy sheave packages provide reliable, low-friction performance at high loads. The high axial loads are carried by Torlon® roller needle bearings, while side thrust loads are taken up by Acetal ball bearings. Block sheave and cheeks are manufactured from the highest quality alloy for maximum strength. The cut-away design minimises weight and allows easy fresh water rinsing of salt and debris from the bearings. Blocks can be disassembled for servicing or customisation.
