FAFNIR - MM9313WI 5H QU

Details

The MMWI 5H QU bearing is a high-precision, matched quadruplex set of four angular contact ball bearings, primarily designed for ball screw support applications in industrial machinery. These bearings are manufactured to manage high axial thrust and radial loads while maintaining extreme precision, often used in CNC machines and precision lathes. Non-separable design with a maximum complement of balls and low drag torque for axial rigidity. Material : High-carbon chromium steel rings and balls (GCr15SiMn) with a nylon 6/6 or phenolic cage. Features are : Maximum Complement of Balls, Tighter Preload Control, Extended Service Life, Clean Steel Technology, Total Friction Management, Operating Temperature Range. Applications : CNC Machine Tools, Large Surface Grinders, Robotic Systems, Machine Tool Spindles, Aerospace & Defense, Medical and Diagnostic Equipment, Servo-Controlled Machinery, Precision Actuators. MM=Super Precision, WI=Internal Design & Contact Angle, 5H=High Capacity, QU=Quadruplex Set.
