Palier de sécurité pneumatique STO/STW

pour arbre de bobinage

Présentation
The XW Machinery STO/STW and FLO/FLW Safety Chuck is designed for high-speed winding and unwinding systems in printing, slitting, packaging, film converting, lithium battery, textile and paper industries. Built for stable torque transmission and fast shaft loading/unloading, this industrial safety chuck provides a secure and efficient connection for air expanding shafts while reducing downtime during roll changes. Available in flange-mounted (FLO/FLW) and foot-mounted (STO/STW) configurations, the safety chucks are manufactured with high-strength alloy steel or lightweight aluminum options to meet different machine requirements.
