For bobbin forming
As a core precision component within spinning machinery chuck systems, the conical lock ring is engineered from high-performance wear-resistant nylon (PA6).
Through specialized processing, it achieves a low friction coefficient, superior wear resistance and exceptional dimensional stability with a precision tolerance of ±0.02mm. It is perfectly calibrated to the tolerance standards of the three major Japanese brands machines (TMT: Toray, Murata, Teijin), ensuring zero-interference installation and optimized vibration frequency synchronization, which significantly extends the chuck maintenance period.
The chuck lock ring is a critical consumable component that ensures the winding quality of synthetic filaments. Its primary function is to work in coordination with the chuck grips and springs to securely lock the paper tube onto the high-speed rotating chuck through physical expansion. In high-speed spinning processes like POY and FDY, where winding speeds often exceed 3,000 m/min, the performance of the lock ring directly dictates the stability of the tube's grip and the overall dynamic balance.
Our grip rings are engineered using wear-resistant polyester as the base material. After undergoing specialized processing, they exhibit a low friction coefficient, superior wear resistance, and exceptional dimensional stability. Each ring undergoes rigorous multi-stage quality inspections before leaving the factory. This ensures a perfect fit within the tolerance systems of the three major Japanese TMT brands (Murata, Teijin, and Toray), achieving zero-interference installation and vibration frequency optimization, which significantly extends the maintenance cycles of your chucks.
