Bearings: The 4h" Block is fitted with special bronze bush but can be fitted with taper roller bearings with special bronze bush if requested.

These capacity loads are based on a Factor of Safety of 4:1 and the Blocks are proof tested to twice this capacity load. The table also details a comparative capacity load to Factor of Safety 2:1 so that the users may compare the 'High Load' Blocks with alternative makes based on this Lower Safety Factor
