Precision Lock Shaft Nut (PN 052156) for Reliable Auto Cutter Machine Performance

The 052156 Precision Lock Shaft Nut is a mission-critical spare part engineered for auto cutter machines, proudly manufactured by Makerboni in Guangdong, China. As a core component for shaft fixation systems, it delivers unmatched reliability in industrial cutting operations, securing rotating shafts to prevent slippage and misalignment—factors that directly compromise cutting accuracy and machine longevity. Certified by SGS for international quality and safety standards, this lock shaft nut is trusted in high-tolerance cutting workflows across Europe and the United States.

Crafted with precision engineering, this lock shaft nut eliminates axial movement and rotational slippage of auto cutter shafts, maintaining consistent alignment even under high torque and mechanical vibration. Manufactured using advanced MIM (Metal Injection Molding) technology, it boasts complex geometric accuracy that outperforms traditional machining, ensuring seamless integration with existing auto cutter systems and reliable performance in demanding industrial environments.

Our 052156 Lock Shaft Nut stands out with superior material quality and industrial-grade durability. Available in high-strength variants such as hardened steel or brass, it weighs just 0.047 kgs while delivering exceptional wear resistance and mechanical stress tolerance—exceeding the demands of continuous industrial operations. With thread tolerance as low as ISO H6 and verticality up to 0.005mm, it ensures flawless shaft fixation, reducing maintenance frequency and secondary damage to bearings or shafts.

As a professional manufacturer, Makerboni adheres to strict quality control protocols, with each 052156 Lock Shaft Nut independently certified by SGS to meet global safety and performance standards. The advanced MIM technology we utilize ensures batch consistency and complex geometric precision, outperforming traditionally machined alternatives. Every unit undergoes rigorous testing to verify thread accuracy, load-bearing capacity, and vibration resistance, guaranteeing reliability for high-tolerance auto cutting applications.
