♦ This SKF Locknut is gradually used for clamping the bearing end caps of rotating fitness moving parts, such as the locking of rolling bearings at the mounting end of ball screws. It has a strong anti-loosening effect, simple structure, beautiful appearance and small radial dimensions.
♦ SKF Locknuts are used to locate bearings onto a shaft. Additionally, they can be used to mount bearings with a tapered bore onto tapered shaft seats and adapter sleeves, and to dismount bearings from withdrawal sleeves. Lock nuts are also frequently used to secure gears, belt pulleys and other machine components.
Lock nuts have to be secured to prevent unintentional loosening by:
• A locking device that engages a keyway in the shaft or key slot in the adapter sleeve,
• Or a locking mechanism integrated in the nut.
The self-locking nut can be rolled to make the threaded hole of the nut into a symmetrical oval with uniform curvature change, and the pitch increases along the threaded hole axially, resulting in interference with the bolt, which can obtain a more stable locking torque.
1, material strain hardening
2、Low circumference fatigue
3、Friction coefficient
4、Manufacturing and assembly
5、Closing value
When choosing or replacing a lock nut, there are a number of factors that should be taken into consideration. They include, but are not limited to:
