UM-50A Hydraulic Thread Rolling Machine

Built for the production of small-to-medium precision threads and fasteners. It offers great flexibility and stable, long-term high quality in a compact body.

Dual-Mode Flexibility: In-Feed & Thru-Feed

Features a built-in switch. Toggle between short-part in-feed and unlimited long-part thru-feed with just one click. It easily meets all your order requirements.

Rigid Square Slide Rails

Made with a strong FC-25 cast iron body and high-frequency hardened square rails. The slide plate will not shake or loosen under continuous heavy loads. This ensures long-term stability and precision.

Precision Transmission & Low Noise

The heat-treated worm gear meshes perfectly with top-quality phosphor bronze worm wheels. It runs ultra-smooth and quiet, reduces friction wear, and extends the machine's lifespan.
