About This Product

■World's thinnest lock nut

Adopts a unique locking mechanism to achieve highest class locking force with a single nut.

■ Uniform locking from all 360° circumference directions

・Extremely high perfect concentricity accuracy ・Simple work process of just tightening Precise bearing lock with high end face accuracy ・High manufacturing technology and reliability realize the locking mechanism Increased by 50%. Delivers up to 50% higher locking force than lock nuts made by other companies.

■Innovative locking mechanism ・Extremely high perfect concentricity accuracy

SPIETH's know-how and technology, which has been proven in the market for many years, is utilized in the SFL series. Thanks to SPIETH's unique elastic membrane structure, the female thread of the SFL nut is "forced" to contact the thread perfectly without any gaps. As a result, the nut, male thread, and flank assembly are removed, making it possible to achieve extremely high concentricity accuracy.

■Product strengths

・Because it efficiently locks the male thread from all 360° circumferences, it exhibits higher locking force than similar lock nuts with the same installation space. ・Highly reliable bearing retention ・Using the highest level of manufacturing and processing technology, we reduce variations in the finish of flat rock, which requires high-precision processing, and provide products with higher quality and reliability.

■100% KM compatible. Shaft lock nuts with key grooves are a thing of the past.

・Bearing washer (chrysanthemum washer) is not required ・No need to break the detent key ・No extra items such as washers, keyway processing, adhesives, etc. are required. Just tighten the flat lock and you're done! ・Wide range of usable temperatures ・Can be used even in low temperature environments ・Can be used in high temperature environments up to 200℃

■Summary

The innovative locking mechanism of the SFL series not only holds bearings, etc., but the world's thinnest and flat design saves space in applications. The SFL series is dimensionally compatible with KM nuts and can be replaced with DIN981 standard nuts including washers. Based on SPIETH's long-renowned design philosophy, this new locknut offers a higher locking force than other products of similar dimensions.
