FAFNIR - MM9321WI 3 QU

Details

The MMWI QU is a high-precision, imperial-sized quadruple set of ball screw support bearings. This set is specifically engineered for applications requiring extreme axial rigidity and high-precision motion control, such as CNC machine tool feed drives. Material :The rings and balls are made from high-purity steel to maximize resistance to rolling contact fatigue and ensure a longer service life. Typically utilizes a polyamide (nylon) cage. This material is chosen for its high elasticity, lightweight nature, and self-lubricating properties, which help reduce noise and heat generation compared to metal cages. Features are : Maximum Ball Complement, Clean Steel Technology, Axial Running Tolerances, Controlled Width Tolerances, Speed Capability, Super-Finished Raceways, Compact Design, Low Heat Generation. Applications : CNC Machining Centres, Stamping Presses, Semiconductor and Electronics Production, Aerospace and Defense, Medical and Precision Measurement. MM=Super Precision, WI=Internal Design & Contact Angle, QU=Quadruplex Set.
