Screw jacks, screw jacks with ball screw or trapezoidal screw
Screw jacks manufactured entirely in Europe The alternative to hydraulics for high loads with ball screw or trapezoidal screw
Screw jacks convert a rotary movement of an electric, hydraulic, pneumatic motor or a manual rotary movement into linear push or pull movements.
Screw jacks can be used both individually and in various lay-out lifting systems with connecting shafts, couplings and transfer gearboxes. Screw jacks enable synchronised, smooth lifting movements even when the load is not evenly distributed. SERVOMECH worm gear screw jacks can be used for both tension and compression loads, in vertical upwards or downwards or horizontal installation positions.
With a specialised Italian production facility with a very high vertical range of manufacture (around 95%) and continuous quality control throughout the manufacturing process, Servomech guarantees the highest product quality and reliability. Specific requirements can be realised flexibly and quickly. Whether large series or small quantities.
We want to understand your requirements and needs and translate them into reliable, competitive and durable products and solutions.
Screw jacks with ball screw
The new series of Servomech ball screw jacks far exceeds the application limits of traditional trapezoidal screw jacks.
The use of screw jacks with ball screws enables high linear lifting speeds and continuous operation. There is no wear on the ball nut and no axial play. Energy consumption and required motor power can be halved. SERVOMECH worm gear screw jacks can be used for both tensile and compressive loads, in vertical upwards or downwards or horizontal installation positions.
They are therefore the right products to combine ever higher performance requirements for your machines with greater energy efficiency.
The ball screw jacks consist of 3 large series: MA BS, SJ BS and HS
Recirculating ball screw jacks - MA BS: Model A and Model B
High-performance series suitable for a continuous operating cycle (100%) / continuous operation
MA BS model A with travelling screw
MA BS Model B with travelling nut
Ball screw from Ø 16 mm up to Ø 120 mm
Load capacity from 5 kN up to 350 kN
Gear ratios from 1:4 to 1:32
Ball screw jacks - SJ BS: Model B
Screw jack with recirculating ball screw suitable for intermittent operation (up to 70%)
SJ BS model B with travelling nut
Ball screw from Ø 16 mm up to Ø 140 mm
Load capacity from 5 kN up to 800 kN
Gear ratios from 1:4 to 1:36
Recirculating ball screw jacks - HS: Model B
Screw jacks for high lifting speeds (HS = High Speed) suitable for a continuous operating cycle (100%) / continuous operation
HS model B with travelling nut
Ball screw from Ø 25 mm up to Ø 80 mm
Load capacity from 10 kN up to 200 kN
Gear ratios from 1:1 to 1:4 with Gleason gearing
Screw jacks with trapezoidal threaded spindle
The electromechanical linear actuators from Linearmech are reliable products for low to medium forces and lifting speeds. Commissioning and operation are well thought-out and simple. The linear cylinders are the ideal alternative to pneumatic cylinders. Linear-Mech actuators are particularly suitable for applications in which the position must be maintained under tensile or compressive load.
Trapezoidal screw jacks - MA: Model A and Model B
Screw jacks with trapezoidal screw suitable for intermittent operation
MA model A with travelling screw
MA model B with travelling nut
Trapezoidal spindle from Ø 18 mm to Ø 100 mm
Load capacity from 5 kN to 350 kN
Gear ratios from 1:4 to 1:32
Trapezoidal screw jacks - SJ: Model A and Model B
Compact series with trapezoidal screw suitable for intermittent operation
SJ model A with travelling screw
SJ model B with travelling nut
Trapezoidal spindle from Ø 18 mm to Ø 160 mm
Load capacity from 5 kN to 1,000 kN
Gear ratios from 1:4 to 1:36
