Precision Balance Nuts SBL Series

The locking method is a six-point locking system with a 30° thread half-angle. This is superior to the three-point locking system, ensuring that all six fixing copper parts are evenly and completely engaged with the male thread, resulting in a more perfect anti-loosening effect. The nut itself has precision-ground internal threads, end faces, back faces, and outer circles to reduce potential balance issues and wind shear noise problems that may occur during high-speed rotation.

This type of nut differs from the SBL-A nut in that it features an adjustable balance screw hole on the back, solving the inconvenience and precision issues associated with balancing high-speed spindles. This design, combined with the company's developed noise-reducing screw to plug the balance screw hole, completely eliminates noise issues caused by high speeds and wind shearing.

This type of nut differs from the SBL-A nut in that it features an adjustable balance screw hole on its outer circumference. When the spindle design cannot use the SBL-B type, this nut is the best alternative. Furthermore, this design, combined with the company's developed noise-reducing screw to plug the balance screw hole, can completely reduce noise issues caused by high speeds.

The locking methods are radial three-point (below M45) and radial six-point (above M50). Its thickness is thinner than other products, making it suitable for situations where the thickness of the nut is limited and other products cannot be used. A balance screw hole is added to the back of the nut itself, which solves the inconvenience and accuracy issues of adjusting the balance of high-speed spindles. Combined with a noise-reducing screw, it can reduce noise problems caused by high speeds.

This type of nut differs from the SBL-D type in that its balance screw hole is located on the outer circumference of the nut. When the balance adjustment cannot be made from the back, this type is the best alternative. When used with a muffler screw, it can reduce noise caused by high speeds.

The noise-reducing screws are made of PC fiber, which is lightweight and has stable properties. Their function is to eliminate high-frequency noise generated by the balance screw holes of the main body or accessories of a high-speed spindle during high-speed operation. They also keep the balance screw holes clean, preventing rust from affecting balance accuracy and ensuring spindle life and precision.
