A full contact bearing provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Glass Fibre reinforced nylon sheave, alloy cheeks and stainless fixings complete the durable package.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDynamic and high static load performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCore Blocks incorporate a full contact acetal bearing on a polished stainless steel race to maintain low friction performance under heavy loads. Ball bearings are configured to act as a thrust bearing between the sheave and checks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect; particularly important for foot blocks\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUniversal head\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe head assembly incorporates a brass bearing washer to provide smooth 360° rotation of the post and shackle.
