Precision Lock Nut "TWIN FU-NUT"

Precision lock nut of the pre-bleeding torque type.

"TWIN FU-NUT" is a precision lock nut of the pre-breling torque type. With two friction rings (special springs), it further enhances the anti-loosening performance of the "FINE U-NUT." By simultaneously machining the screw and the seating surface, the runout accuracy of the seating surface relative to the screw is secured to the 1,000 micrometer range (mm). This product, which combines high runout accuracy and anti-loosening functionality, maintains precise bearing rotation at all times. 【Features】 ■ Precision lock nut of the pre-breling torque type ■ Enhanced anti-loosening performance of the FINE U-NUT ■ Tightening is completed simply by tightening the nut ■ Reusable ■ Screw accuracy is ISO4H *For more details, please refer to the PDF document or feel free to contact us.

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 until the friction ring contacts the threads of the shaft. ■Step 3 - Confirm that the friction ring has made contact with the end of the shaft. ■Step 4 - Use the dedicated tightening tool for the FINE U-NUT. (It can also be installed with a hook spanner.) ■Step 5 - Hold the shaft part of the ratchet handle and gently turn to tighten. ■Step 6 - Check whether the inner ring of the bearing is in close contact with the seating surface of the TWIN FU-NUT, and whether the threaded part of the shaft extends more than 2 pitches from the friction ring. *For more details, please refer to the PDF document or feel free to contact us.
