FAFNIR - MM9311WI 3H DU

Details

The MMWI 3H DU bearing is a super-precision duplex angular contact ball bearing specifically engineered for ball screw support applications in CNC machinery and high-precision industrial equipment. It is designed for maximum axial rigidity, low drag torque, and extreme control over lateral eccentricity. Material : Typically features a Phenolic outer land-riding cage or a Nylon 6/6 cage to allow for a maximum complement of balls and higher load capacity. Features are : Non-Separable Design, Tighter Width Tolerances, High Load Capacity, Low Drag Torque, Enhanced Machine Uptime, Speed Capability. Applications : Grinding Machines, Robotic Arms and Actuators, Servo-Controlled Machinery, Assembly Lines, Semiconductor and Electronics Fabrication, Aerospace and Defense, Medical and Laboratory Equipment, Packaging and Material Handling. MM=Super-Precision, WI=Internal design with outer land-riding cage, 3H=High Capacity Design, DU=Universal Duplex set.
