Tianji CE Certified Steel-Aluminum Alloy Lug Type Air Shaft

In high-speed textile manufacturing, every millisecond counts. Tianji’s Lug Type Air Shafts eliminate costly disruptions with zero-slip performance.

💎 Core Features & Unmatched Advantages (FAB)

Precision engineering that solves real production bottlenecks — each feature paired with a visual insight.

Premium Steel-Aluminum Alloy

Combines lightweight aluminum body with hardened steel lugs for extreme wear resistance. Achieve 40% longer service life while reducing roller inertia for faster acceleration and less energy consumption.

✔ Up to 40% extended lifespan & faster ramp-up

Precision CNC Machining

Ultra-high concentricity with <0.02mm tolerance and mirror-like surface finish. Guarantees perfectly even tension across the entire web width, eliminating wrinkles, baggy edges, and dimensional defects.

✔ Concentricity <0.02mm — flawless tension control

Ergonomic Lug Design

Optimized contact angle distributes gripping force evenly without crushing the core. Provides maximum torque transmission even at maximum speed, completely eliminating slippage and protecting expensive textile cores.

✔ Zero slippage · Core protection guaranteed

Fully Customizable OEM

Tailored length, diameter, lug count, lug height, and air inlet positioning based on your CAD drawings. Seamless drop-in replacement for any CNC textile roller, slitter, or winding machine – no retrofitting required.

✔ Perfect integration — we match your unique specs

CE Certified Quality

Manufactured in strict compliance with international safety and performance standards. Each shaft undergoes rigorous air-tightness, dynamic balance, and fatigue testing, ensuring hassle-free global import and operational peace of mind.

✔ CE approved · Full compliance · Reliable
