FAQ
This nut prevents bearing looseness, securely maintaining a near-perfect tightened state. The powerful looseness prevention effect resists vibration due to high-speed rotation and shock caused by forward and reverse rotation even when the preload is low.
This revolutionary anti-loosening set screw (hexagon socket head type) uses the wedge principle. Use for die pins in place of welding and adhesives to improve operability and greatly reduce overall costs.
