4 Pcs LMF12UU Linear Ball Bearings 12mm Bore Round Flange for CNC 3D Printer

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.
