The precision 2-stage ball bearing system uses high compression grade Acetal ball bearings and a secondary full-contact bearing for minimum friction across the full working load range, supported by a fibre-reinforced load frame computer modelled using advanced stress analysis. The two-way lashing head allows alignment at 0° or 90° orientation, and accepts the RF1850S shackle in both orientations to create a conventional loop top block. SP versions feature a Nylatron® sheave suitable for both rope and wire.\u003c\/p\u003e\u003cbr\u003e\u003cstrong\u003eType of Block:\u003c\/strong\u003e Single\u003cbr\u003e\u003cstrong\u003eSheave Diameter:\u003c\/strong\u003e 30mm\u003cbr\u003e\u003cstrong\u003eBreaking Load:\u003c\/strong\u003e 600kg\u003cbr\u003e\u003cstrong\u003eMaximum Working Load:\u003c\/strong\u003e 300kg\u003cbr\u003e\u003cstrong\u003eMaximum Rope Diameter:\u003c\/strong\u003e 8mm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 22g\u003cbr\u003e\u003cstrong\u003eSheave:\u003c\/strong\u003e High compression strength carbon black Acetal\u003cbr\u003e\u003cstrong\u003eBall Bearings:\u003c\/strong\u003e High compression strength Acetal\u003cbr\u003e\u003cstrong\u003eFrame\/Cheeks:\u003c\/strong\u003e Toughened, glass fibre reinforced Nylon\u003cbr\u003e\u003cstrong\u003eLink:\u003c\/strong\u003e UV stabilised, multi-strand impregnated SK75 Dyneema®\u003cbr\u003e\u003cbr\u003eItem Code.
