- 12mm Linear Round Flanged Ball Bearing (LMEF12UU) are engineered for high-precision linear motion across linear shafts, providing consistent performance in demanding mechanical and automation systems. Utilising an internal arrangement of recirculating ball bearings, the linear ball bushing reduces friction and enables smooth, accurate movement under load. A robust steel shell with a round flange combined with dual rubber seals enhances durability and simplifies mounting, making this bearing ideal for high-cycle and industrial environments. Key Features High-Precision Motion: Recirculating ball design delivers accurate, low-friction travel along linear shafts. Flanged Mounting: Integrated round flange allows easy and stable installation onto surfaces. Contaminant Protection: Integrated rubber seals prevent debris intrusion for extended operational life. Optimised for Linear Shafts: Standardised dimensions ensure compatibility with linear motion systems. Application Flanged linear bearings are optimised for use with linear shafts in CNC machines, 3D printers, robotics, and automated machinery. They provide essential load support and smooth motion in linear drive systems, with the added advantage of simplified mounting. Their sealed construction makes them particularly suited for environments where exposure to dust and debris could otherwise compromise performance.
