Tips: Detection and maintenance of screw rod support bearing clearance

If the dial-gage indicator which measures the screw rod does not swing when the screw rod moves in forward direction and opposite direction, it shows that the screw rod does not move. The maximum and minimum measured value difference is the distance of the axial float of the screw rod. At this point, we will check whether the back cap of the supporting bearing is locked, whether the bearing is worn out or not, and the pre load bearing washer is suitable. If the bearing is damaged, the bearing needs to be replaced and the pre-loaded washer needs to be made again so as to tighten the back cap. The screw rod axial float largely depend on the precision of  supporting bearing preload washer. The most ideal condition of the screw rod installation accuracy is that there is no positive and negative clearance, and the support bearing should have the interference of about 0.02mm.
