Inside runs PolarWave's own bearing system, with PEEK roller bearings and zirconia ceramic side elements. The ceramic side elements cut friction when the block is loaded from the side, so the sheaves keep turning freely when the line doesn't come in square.\u003c\/p\u003e\u003cp\u003eAt 355 g it carries a 2 tonne working load, and the stainless steel rivet core, also developed by PolarWave, takes it to a 5 tonne breaking load.\u003c\/p\u003e\u003ch3\u003eWhy Choose PolarWave\u003c\/h3\u003e\u003cp\u003ePolarWave designs and builds lightweight, high-performance sailing hardware in Slovenia.
