The Hydraulic Bolts Thread Rolling Machine NRS-35T is a high-performance thread forming solution designed for manufacturing precision bolts, screws, shafts, and other threaded components. Featuring a strong hydraulic drive system, rigid machine structure, and advanced PLC-controlled pressure regulation, this machine ensures stable operation, long service life, and consistent thread quality.
Built with imported high-quality components including the universal joint, frequency converter, hydraulic system, and micro-response switches, the NRS-35T provides excellent durability, low maintenance requirements, and reliable performance for continuous industrial production.
Designed with a two-point L-shaped left and right frame assembly structure.
Provides excellent resistance against deformation during heavy-duty rolling operations.
Specially processed slide plates improve wear resistance and maintain stability under long-term pressure.
Ensures smooth operation and extended machine lifespan.
Equipped with a hydraulic frequency conversion system and PLC program control.
Automatic impact pressure adjustment improves rolling consistency.
Stable oil temperature control prevents quality variations caused by temperature changes.
Delivers high precision thread forming with excellent repeatability.
The NRS-35T uses a high-performance piston-type hydraulic pump for stronger and more stable pressure output.
Hydraulic pump options:
Piston pump: Maximum output pressure up to 210 kg/cm²
Blade pump: Maximum output pressure up to 120 kg/cm²
The piston hydraulic system provides:
✔ Higher rolling force
✔ Better pressure stability
✔ Improved thread quality
✔ Longer operating life
