Product Description

Chuck Tension Segment for Barmag-Compatible Winders

In high-speed filament yarn winding, the chuck tension segment is a critical wear-resistant component that directly contacts the paper tube to transmit torque. Its machining accuracy and material performance dictate the stability of paper tube clamping and the dynamic balance of the chuck during high-speed rotation.

Addressing common field issues: Tube Slippage Shedding Chuck Vibration
1. Core Functions & Working Principle

Installed around the perimeter of the winder chuck, the tension segments are pushed outward by the internal inclined drive mechanism — converting axial force into radial expansion force to firmly grip the inner wall of the paper tube upon startup.

Secure Clamping: Ensures zero slippage and axial shifting of the paper tube.
3000–5000 m/min
Efficient Transmission: Distributes chuck driving torque evenly around the paper tube circumference for smooth acceleration and deceleration.
Rapid Release: Internal springs pull the segments inward at full package to quickly reduce diameter, allowing resistance-free unload.
2. Material Properties & Tube Protection
High-Toughness Composite Polyester
Wear-resistant engineering composite plastic with optimal elasticity, providing sufficient gripping force without crushing or scratching the paper tube.
Durable & Long-Lasting
Exceptionally low wear rate under high-frequency expansion and contraction friction, extending replacement cycles and reducing maintenance downtime.
3. Critical Craftsmanship: Weight Control & Dynamic Balance
i
At high-speed rotation reaching tens of thousands of RPM, even minor mass deviations are magnified exponentially by centrifugal force. All tension segments within the same chuck set are precisely weighed and matched before leaving the factory. By strictly controlling the weight tolerance within each set, we eliminate high-frequency chuck vibration caused by mass imbalance at the source, protecting the main spindle from damage.
