FAFNIR - MM9311WI 3H QU

Details

The MMWI 3H QU bearing is a super-precision, quadruplex (set of four) angular contact ball bearing set specifically designed for high-performance ball screw support applications. It is engineered to provide maximum axial rigidity and extreme control over lateral eccentricity, typically used in machine tool axes where high positioning accuracy is critical. Non-separable angular contact design with a maximum complement of balls to ensure the highest possible load capacity. Material : High-quality steel for both rings and balls with a phenolic (textile reinforced) outer land riding cage or a specialized steel cage for high-speed stability. Features are : High Load Capacity, Low Drag Torque, Speed Capability, Open Configuration. Applications : CNC Milling and Grinding, Machining Centers, Robotics and Automation, Aerospace Components, Medical Equipment, Automotive Systems, Elevators and Assembly Lines, Linear Motion Products, Electric Injection Moulding, Woodworking Machinery, Power Generation, Conveyor and Material Handling, Pumping Systems, Aerospace Control Surfaces. MM=Super Precision, WI=Internal Design & Contact Angle, 3H=Heavy Preload, QU=Quadruplex Set.
