Bearing Lock Nut "FINE U-NUT"
Suitable for countermeasures against loosening due to reverse rotation from high-speed motor rotation, as well as sudden acceleration and sudden stops! Also contributes to improved rotational balance!
The "FINE U-NUT" and "TWIN FU-NUT" are bearing locking nuts that eliminate the need for traditional keyway machining on shafts and the installation of toothed washers. They are ideal for counteracting loosening due to vibrations during motor operation and reverse rotation from high-speed rotation. They allow for arbitrary and appropriate positioning, making torque management easy. They generate "power" in various industrial machines and improve the rotational balance of bearings. Additionally, they have achieved a reduction in rotational losses of equipment and a decrease in power consumption. 【Features】 ■ Reusability: Can be reused ■ Easy fastening: No skilled techniques required ■ Labor-saving simplification: No keyway machining on shafts needed, simplifying installation work ■ Balance: Improved rotational balance of shafts and bearings ■ Lightweight: Can use thinner hollow shafts than before ■ Cost reduction: No need for traditional machining, parts, or techniques *For more details, please refer to the PDF document or feel free to contact us. *CAD data is also available for download.
basic information
【Installation Procedure】 ■ Step 1 - Pass the bearing through the shaft. - Confirm that the end of the threaded part of the shaft has been chamfered (equivalent to 1 pitch) before applying lubricant. ■ Step 2 - Manually screw in the shaft until the friction ring makes contact with the threads. ■ Step 3 - Use the dedicated tightening tool for the FINE U-NUT. (It can also be installed with a hook wrench.) ■ Step 4 - Hold the shaft part of the ratchet handle and gently turn to tighten. ■ Step 5 - Check if the inner ring of the bearing is in close contact with the seating surface of the FINE U-NUT, and whether the threaded part of the shaft extends more than 2 pitches from the friction ring. - When removing, unscrew with the tightening tool until the friction ring is free from the threads of the shaft.
