uxcell 2Pcs LM4UU Linear Ball Bearings, 4mm Bore Dia, 8mm OD, 12mm Length Double Side Rubber Seal Linear Motion Bearing for 3D Printer CNC Machine Applications, ABEC3
Package and Size: You will receive 4 pcs LM10UU linear ball bearings with the Size of 10 x 19 x 29 mm / 0.39 x 0.75 x 1.14inch (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
