FAFNIR - MM9321WI 3 QU | Angular Contact Ball Bearing Ballscrew | 101.60 × 145 × 88.90 mm

Details

FAFNIR MM9321WI 3 QU is an angular contact ball bearing ballscrew with inner diameter 101.60 mm, outer diameter 145 mm and width 88.90 mm. Additional specifications include bore type CYLINDRICAL, cage YES and lubrication STANDARD.

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.
