The definitive version of the locking nut
It has passed over 50 years since the birth. FUJILOK U-NUT is now the highly regarded as the first name in Locknuts across all industries from steel structures such as railways and connecting bridges to automobiles, motorcycles, and on up to industrial machines. No matter how harsh the use environment is, the FUJILOK U-NUT which is required for safety and peace of mind is the definitive version of the locking nut which continues to evolve in terms of durability, vibration resistance, etc. as well as locking performance.
Fastening revolution of bearings
With FINE U-NUT, variable positioning at the appropriate location is possible and torque management is also easy. This groundbreaking lock nut for use with bearings makes unnecessary of machining key ways on shafts, lockwashers, and a high degree of skill for installation. FINE U-NUT improves the rotational balance of bearings that provide power in all machine industries.
Prevailing torque type precision locknut
The industry's first prevailing torque type precision locknut. The locking function of the FINE U-NUT is strengthened by having two friction rings (specialized springs). Through the threads and the bearing surface being created at the same time, the TWIN FU-NUT provides both high bearing surface run-out accuracy and an excellent locking function and it always maintains accurate bearing rotation.
