NADELLA - ZARN4075

Details

The ZARN is a Combined double-direction axial/radial super-precision bearing commonly manufactured by Nadella. It is engineered primarily for machine tool applications, such as supporting ball screw drives, where high radial and axial rigidity are required in compact spaces. Houses a radial needle roller assembly to absorb heavy radial forces, wedged between two thrust cylindrical roller to sustain bi-directional axial thrust. Material : It is made of high-carbon chrome steel (inner/outer rings and rollers). Features are : High Structural Rigidity, High-Speed Performance, Space-Saving Envelope, High Tilting Stiffness, Low Starting Torque, Interchangeable Design, Broad Temperature Range, Built-in Relubrication, Optimized Friction and Heat Dissipation. Applications : Printing & Packaging Systems, Textile Machinery, Wind Turbine Pitch Drives, Optical Grinding Equipment, Medical Centrifuges, Semiconductor Manufacturing, Aerospace & Defense Support Equipment.
