2 pieces KFL001 (KFL12) mounted flange block bearings for 12 mm linear shafts. Selfaligning zincaluminum alloy support housings designed to hold and guide diameter 12 mm rods for reliable linear motion. Key benefits Secure support for 12 mm shafts: Provides steady, lowfriction guidance to keep linear shafts aligned during motion. Selfaligning function: Compensates for small shaft misalignment and mounting surface irregularities, reducing binding and premature wear. Durable, corrosionresistant housing: Zincaluminum alloy construction offers strength and improved resistance to corrosion compared with plain cast housings. Easy replacement and upgrade: Standard KFL001 (KFL12) form factor suits common linear motion systems and makes maintenance straightforward. Pack of two: Includes two identical KFL001(12mm) flange bearings for replacing or adding supports in pairs. Key attributes Model: KFL001 (also referenced as KFL12) Quantity: 2 pieces Inner diameter (ID): 12 mm — compatible with 12 mm linear motion shafts and rods Type: Mounted flange block bearing, selfaligning Housing material: Zincaluminum alloy Functionality: Support and guide linear motion shafts, reduce friction and misalignment How it solves problems Eliminates shaft wobble and reduces vibration by holding the shaft securely in a fixed position. Selfalignment prevents uneven loading when mounting surfaces are not flat, extending both shaft and bearing life. Robust housing protects the bearing insert and simplifies installation in machines and fixtures. Typical applications CNC and milling tables: Provide stable support for 12 mm guide shafts in light CNC machines and small router tables. 3D printers and CNC routers: or upgrade linear shaft supports to improve print or cut quality and reduce mechanical play. Automation and robotics: Support linear actuator shafts and guide rails in pickandplace assemblies, conveyors, and lightweight robotic arms. Linear slides and jigs: Use in custom fixtures, test rigs, and hobby projects where compact, reliable shaft support is required. Installation and maintenance tips Confirm shaft diameter is 12 mm before installation. Mount on a reasonably flat surface and tighten fasteners evenly to preserve selfaligning capability. Periodically inspect for wear and contamination; bearings in pairs when worn to maintain alignment and performance. Included 2 x KFL001 (KFL12) ID12mm mounted flange block bearings (selfaligning, zincaluminum alloy housing) This set is intended for users needing standardized, durable supports for 12 mm linear shafts in light to mediumduty motion applications.
