For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eUniversal Bearing\u003c\/b\u003e\u003cbr\u003eDynamic and high static load performance\u003cbr\u003e\u003cbr\u003eThe Ronstan Universal Bearing incorporates our proven 2-stage bearing system\u003cbr\u003e\u003cbr\u003e\u003cb\u003eStage 1\u003c\/b\u003e - Under moderate loads, Acetal ball bearings ensure minimum friction.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eStage 2\u003c\/b\u003e - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.\u003cbr\u003e\u003cbr\u003eAdditionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn't perfect.
