machine screw actuators

NOSEN new Europe-type machine screw actuators RNF-Series is popular on the world market with below features:
1. Same dimensions with ZIMM, Pfaff-silberblau, Grob GmbH, Inkoma, Servomech,
Unimec, Thomson Linear etc.
2. Model: RNF016, RNF018, RNF020, RNF030, RNF040, RNF055, RNF060, RNF070, RNF080, RNF100, RNF120
3. Function: Precisely controlled lifting, lowering, pushing, pulling and rolling movements
4. Self locking trapezoidal screw, heavy duty, low efficiency, use infrequently
5. Arrangement: Single units, in pairs or multiple jacks systems, fully synchronization
6. Power Source: Electrical driven, manual operated
7. Travel Speed:
* 1 turn 1 mm travel, 1500 mm/min
* 1 turn 0.25 mm travel, 375 mm/min
8. Tolerance&Backlash:
Trapezoidal-type screw end play 0.15 mm, radial play 0.2 mm.
Worm shaft&worm gear play, high speed(N), worm shaft backlash ± 3 degrees, Low speed(L), ± 5 degrees.
9. Lateral Force:
Usually, screw jack only loads lift screw axial loading, don't permit to load any lateral force. Any lateral force will reduce screw jack working life, even damage screw jack. We suggest, lateral forces that may occur should be taken by an external guide rail.
10. Anti-rotation Devices:
Single screw jack application, isn't guided and without any guide rails, lifting screw does not do linear motions, only rotation, especially light loading. If that is the case, need to extra add anti-rotation devices.
11. Stop Collar:
Prevents the screw from being removed from the jack gearbox. Following clients requirement, we fit stop collar for screw jacks. The stop collar cannot be used as a fixed stop.
12. Application Industries:
Precision lift table, roll forming machines, press machines, tunnel freezer, surface-gringing machines, satellite dish antenna, solar tracking system, sluice gate, theatre stage, slitting line, precision leveler, powered straightener, paper machines, food processing machines, textiles machines etc.
