    The main consideration for a sheave without bearings is Pressure Velocity (PV). In this case the Nylatech Sheave is the bearing. To calculate the load capacity for this situation use the maximum PV value of the grade of Nylatech Cast Nylon to be used. From here calculate the MAXIMUM BORE PRESSURE by PB = PV/V PB = Maximum Bore Pressure (psi)
