High-precision linear motion system in perfect harmony with cylindrical axis Milli Series Linear Bushings
LM20UU
▶ It is the most widely used product belonging to the millimeter series▶ It is a low-cost linear motion system with a precise cylinder in outer diameter and used in conjunction with infinite strokes and cylindrical axes
▶ You can choose between closed, open and adjustable clearance, and you can tell which ones have a dust seal and which are not
▶ The basic dimensions are 32 mm outer diameter, 42 mm length and 20 mm inner diameter, and the basic load rating is 206 N dynamic load and 265 N static load
▶ Since the steel ball and the shaft are in point contact, the working load is small, and since the steel ball rotates with very little frictional resistance, high accuracy and flat movement can be achieved
