We use high-quality materials for all parts, which makes screw jack have a longer life and higher precision.
1)Input drive: worm gear, high-efficiency design, 9-4 or 10-1 copper. reduced axial backlash, with hardened and ground thread and shaft.
2) Acme screws: material: steel C45, subjected to straightening process to ensure the regular alignment in operation, max. pitch error ± 0.05 mm over 300 mm thread length.
3)Housing: monobloc housing designed for a more compact and robust shape, able to carry heavy loads and ensure a high precision level of machining. High resistance materials spheroidal graphite iron are used.
