uxcell 4Pcs LM20UU Linear Ball Bearing,20mm Bore Dia,32mm OD,42mm Length

Key features

• Package and Size: You will receive 4 pcs LM20UU linear ball bearings with the Size of 20 x 32 x 42 mm / 0.79 x 1.26 x 1.65inch (Bore * OD * L). The size is measured manually, there may be slight errors, please understand
• Material: The linear ball bearing is made of bearing steel with excellent compressive strength. It is corrosion-resistant and its hard surface can effectively resist repeated friction between the ball and the track and can be used in long-term operation conditions
• Feature: These linear bearings use double rubber seals at both ends to prevent the intrusion of dust, water and foreign matter. They have high precision, low noise, high speed and low heat, making them suitable for various high-demand places
• High Precision: The high-toughness balls inside the linear bearings roll within precision-ground raceways, ensuring highly linear motion and achieving highly repeatable movement. This also reduces friction during machine operation, improving transmission efficiency and significantly reducing drive energy consumption
• Application: Linear motion bearings are widely used in precision equipment such as electronic equipment, tensile testing machines, digital three-dimensional coordinate measuring equipment, as well as industrial machinery such as multi-axis machine tools, punching machines, automated compressors, food packaging machinery, tool grinders, gas cutting machines, 3D printers, etc
