Step 1: Wash the spindle / ball screw and locknut with oil cleaner and air dry them; loosen the clamping screws of the locknut Step 2: Add lubricating oil onto the thread of the spindle / ball screw and locknut Step 3: Use appropriate tool and torque wrench to do the fixation Step 4: Drive the socket head screws tightly

TorqueandForceCalculationFormula

T = F * K ( N*M )

K = 1/2 { dp * tan ( P*+ß ) + dw * uw } x 10-3 (m)

T: Nut locking torque

F: Nut tightening force dp: Nut effective diameter (mm)

P*: Thread friction angle, P* = tan-1µs ß: Nut lead angle, ß = tan-1 ( pitch/3.142*dp ) µs: Coefficient of friction for nut connecting face ; uw = us ≒ 0.15 dw: The average diameter of friction torgue for nut connecting face.

D+d (mm) ; dw = –––––2

StaticAxialLoadCalculationFormula

F = A * Sh * n

F: Axial Load

A: The area of each thread

Sh: Allowed shearing stress ( Safety factor = 4 ) n: Number of effective thread
