Explanation: Pitch: Designated by "X P".For example, M8 X 0.75 means an 8 mm (0.315″) thread with a pitch of 0.75 mm (0.03″ or 34 TPI).If the "X P" is omitted, the pitch is defined by the Coase Pitch Series according to ISO-261. Number of starts: Designated by "Ph".For example, M8 X Ph2.25P0.75.In this case, 2.25 mm is the lead, and 0.75 mm is the pitch.

Because every time your motor changes direction, its first few steps are wasted while your machine stands still instead of moving. Similarly, a pulley may turn a short distance before it can engage the belt. How to Fix It. For screw-nut assembly, the remedy is to use a tighter lead-screw or ball-screw in the form of anti-backlash nuts.
The conventional type lapping tool shown in Figure 1-a) is simple in design and usually made of gray cast iron (JIS FC20) and cut partially at the middle, to make it 2-slits lap.The threaded portion is made of smooth surface and close to size and shape of the ball screw.

Preload the Ball Screw: Applying a slight axial force to the nut can preload the ball screw and reduce backlash. Choose Low-Lead Ball Screws: Ball screws with a low lead angle inherently have less backlash. Use Precision Ground Ball Screws: Opt for precision ground ball screws with tight tolerances to minimize backlash. 2. Wear and Tear
