Linear Motion Bearing Steel High Accuracy for Industrial Automation LM25LUu LM20LUu LM16LUU Feature: 1. Adopt double-sided dust-proof rubber sealing to prevent foreign matter from entering and prolong service life 2. Adopt nylon retainer, low motion inertia, low starting torsion, less noise and smoother operation 3. High-tech polished surface with high smoothness and high brightness 4. Suitable for industrial automation, aerospace, machine tools, engraving machines, robots and automobiles 5. The linear bearings are frictional and relatively stable, do not change with the speed of the bearing, and can obtain smooth linear motion with high sensitivity and high accuracy. 6. Adopt bearing steel material, durable to use. 7. Outer ring and steel ball are made of bearing steel material, strengthened by heat treatment, increasing life and load 8. Compact structure, easy to install, ordinary linear bearings can be installed in any direction, using the shaft as a support for precise work, and the mounting surface is easy to machine Specification: Item Type: Linear-Motion Bearing Material: Bearing steel LM25LUU: Inner Diameter: Approx. 25mm / 1in Diameter: Approx. 40mm / 1.6in Height: Approx. 111mm / 4.4in LM20LUU: Inner Diameter: Approx. 20mm / 0.8in Diameter: Approx. 32mm / 1.3in Height: Approx. 80mm / 3.1in LM16LUU: Inner Diameter: Approx. 16mm / 0.6in Diameter: Approx. 28mm / 1.1in Height: Approx. 70mm / 2.8in Package List: 1 xLinear-Motion Bearing _x000D_ _x000D_
