NACHI - 7004W1YDFNKE9

Details

Ball Screw Support Bearings, used in high-precision and high-speed machines. This line is also used on other machines that have integrated precision feed actuators. These bearings feature a high degree of rigidity and high load capacity. NKE9 : With one non-contact seal. Features are : NACHI's proprietary seals, which are proven in deep-groove ball bearings, are used to retain injected grease for greater sealing and to prevent contamination by foreign matter. Superior low-start-up torque and low-rotational torque can be used for low-energy applications. Combination bearings are provided with preset preloads, eliminating the need for troublesome installation adjustment using shims and torque measurements. Polyamide resin cage and high-per formance grease produce low-noise design based on standard A-type angular contact ball bearings. The contact angle is 30°.
