Perfect for professionals upgrading CNC machines, 3D printers, or automation equipment, these bearings deliver smooth, low-friction linear motion with extended service life and reliable protection against contaminants. ## Description Descriptions:Material:The slide bearings are made of quality bearing steel, offering high hardness, high precision, good wear resistance, and strong load-bearing capacity. It ensures reliable performance, smooth operation, and an extended service life in mechanical motion applications.Double-Sealed Design:Linear bearings are double-sealed on both sides to effectively block dust, water, and foreign particles, ensuring internal lubrication is retained.Easy to Use:Linear bearings are a crucial component of linear motion systems, converting a rotary drive into precise, smooth, and low-friction linear motion. They are often used in conjunction with cylindrical shafts or guideways. Ensure proper concentricity alignment during mounting and avoid the bearing from eccentric or overload conditions.Wide Application:Linear ball bearings are useful in precision automation equipment such as 3D printers, CNC systems, electronic devices, and food machinery. They are great for mechanical slides, multi-axis positioning tables, and linear guide systems that need high-precision, reliable linear motion.Specifications:Model: LMF12UUMaterial: Bearing SteelInner Diameter: 12mm/ 0.47 inOuter Diameter: 21mm/ 0.83 inTotal Length: 30mm/ 1.18 inBase Diameter: 42mm/ 1.65 inAccuracy Grade: ABEC3Package Contents: 4Pcs x Linear Bearing ## Features - Size & Package: Model: LMF12UU; Inner Diameter: 12mm/ 0.47 in; Outer Diameter: 21mm/ 0.83 in; Total Length: 30mm/ 1.18 in; Base Diameter: 42mm/ 1.65 in; Accuracy Grade: ABEC3; Package Contents: 4Pcs x Linear Bearing - Material: The flange linear motion bearings are made of quality bearing steel, offering high hardness, high precision, good wear resistance, and strong load-bearing capacity.
