Screw jacks
• The FIAMA series of screw jacks is a modular mechanical system, for a complete and versatile solution, which transforms rotary
movements into linear «push/pull» movements.
• Trapezoidal screw in stainless steel, TPN Ø14 thread - 4mm pitch
• Case in anodized aluminium, shafts and gears treated with PRONOX wear-resistant surface hardening
• Trapezoidal screw standard stroke lenghts in mm: 100 - 200 - 300 - 400 - 700 - 1000
• Maintenance-free: lubricated with long-life Klüber grease
• Single lifting jack or combination of multiple units
• Combination with joints, shafts, gearboxes
• Semi-automatic systems with digital or programmable inidcators
• Automatic systems with servomotors
Available on request:
• Supplied complete with fixing flange and extension shaft for display with „OP3“ digital indicator or „EP3“ programmable indicator
(see dimensions MAR40 FL-OP3)
• Stainless steel rigid protection with stainless steel spiral spring up to 650mm stroke
• In case of continuous use, please contact our Technical Dept. In such applications, a grease fitting will be installed to allow
periodic addition of lubricant with a frequency based on the work conditions

| INSTALLATION |
| Installation must not create radial/lateral loads, which are the main cause of failure, on the threaded bar. The plane to which the screw jack is fixed and the threaded bar must be orthogonal and the load and the bar must be coaxial avoiding eccentricity. When applying multiple jacks (connected also by transmissions) the terminals must be perfectly aligned so that the load is uniformly distributed; in this case it is recommendable to use couplings to compensate misalignments. |
| SIZING VERIFICATION |
| • Load (N) = the force which is applied to the threaded bar of the screw jack (10 N ≅ 1 kg) |
| • Linear speed (mm/min) = the desired linear speed of the load; it is recommendable to limit the input rotary speed to max 1500 rpm |
| • Stroke (mm) = it is the linear distance that the load must be moved, generally it coincides with the total length of the threaded bar |
| • Protective cover (optional) = necessary to protect the bar in case of contamination, dust, foreign objects and/or oscillating installation and movements |
| • Torque (Nm) = torque required for the handling of the load |
| RADIAL AND AXIAL LOADS | |
| The loads acting on the shafts can be of two types: radial ‘FR’ (radial force) and axial ‘FA’ (axial force), referred to the axis of the shaft; when ordering specify whether the axial load is pull or push type. FR - force / radial load acting in perpendicular direction to the shaft / axis FA - force / axial load acting of the shaft / axis |
