Circular knitting machine sinkers are core precision components that directly determine fabric quality and machine stability. Mismatched or low-quality sinkers cause 42% of common fabric defects, accelerated needle wear and unplanned downtime.
In 2026, as 35+ RPM high-speed and 32G-40G fine-gauge machines become standard, sinker precision requirements have increased significantly. This guide provides industry-verified selection criteria based on Qattex's 31 years of experience.
Sinkers move radially along the sinker plate, cooperating with needles to form uniform loops. Their core functions:
High-precision qualified sinkers reduce fabric rejection rate by 15-22% and extend needle life by 25-35%.
Match sinker gauge to your sinker plate gauge, not just the cylinder gauge. A difference of more than 0.02mm will cause permanent needle damage and fabric stripes.
Standard gauges: 14G, 16G, 18G, 20G, 22G, 24G, 28G, 32G, 36G, 40G.
Nose thickness is the most important parameter:
Qattex sinkers are manufactured to original factory drawings and compatible with: Mayer & Cie, Terrot, Santoni, Pilotelli and all major Chinese brands.
A: Replace when you see burrs on the nose, needle breakage triples, or nose wear exceeds 0.03mm.
A: No. Regrinding changes critical dimensions and destroys the hardened surface layer.
A: 8000-12000 operating hours for standard nitrided sinkers (24/7 cotton production).
A: Yes, we can manufacture custom sinkers from your drawings or samples (MOQ 1000 pieces).
Choosing the right sinkers is essential for efficient production and high-quality fabric. A small investment in premium sinkers delivers significant returns in reduced downtime and lower rejection rates.
