Repeatability can be critical. Repeatability is how properly a lead screw program can move a load to the same posture consistently.
The PV ranking signifies the maximum allowable mix of axial load and revolutions for each minute (rpm) that a lead screw can endure. It is decided by the heat created through operation as well as the have on expert through the lead screw.
