Mechanical jacks

The mechanical jacks are used to transform the rotary motion into vertical lift or horizontal positioning.

They are massively used in the following areas: for boxing machines, packaging, capping, filling, for medical use, in mixers, solar panels, and for many different uses.

The mechanical jacks Trevi by Sir, by positioning facilitated thanks to the rectangular shape and flattened, are made in anticorodal aluminium, high-quality material which combines lightness and strength to the advantage of being particularly suitable for the anodic oxidation treatment to which all our jacks are submitted.

This process provides for electrochemically creating an oxide layer that protects the metal from corrosion.

The purpose of the anodizing treatment is:

  • improving the corrosion resistance;
  • increase the surface hardness;
  • increase the wear and abrasion resistance;
  • to improve the aesthetic appearance.

Silver is the colour proposed for the anodizing, but there is a wide choice of colours.

The jacks are available in various sizes, and the standard configuration (always ready in stock) are juxtaposed multiple possibilities of personalization, both for the realization of the engine seating that for predispositions and it is always possible to request special pairs.

The excellence of the materials chosen is extended to each component: for all sizes the wheel is integrally made of bronze, without the use of extraneous materials such as steel or cast iron, this in order to ensure the highest strength and rigidity, combined with the corrosion resistance.

The worm is always with ground profile and for sizes 30 and 32 also cemented and hardened.

Our Mechanical Jacks

Jack ideal for light loads and precise movements.

Standard configuration:

  • monoblock carter, anticorodal and anodized aluminium;
  • silver colour;
  • protruding screw for motor coupling with the possibility of fixing with plug or stick;
  • system of pressure fixing;
  • worm with ground profile;
  • bronze wheel;
  • supplied already filled with oil, for eternal lubrication: it does not require maintenance interventions.

Options on request:

  • colour anodization;
  • arrangement for trapezoidal screw, maximum dimensions Tr18x4.

Small jack, not cumbersome and with high strength and precision.

Standard configuration:

  • silver colour;
  • double protrusion screw, solid shaft;
  • worm with ground profile, in hardening steel;
  • bronze wheel;
  • supplied already filled with oil, for eternal lubrication: it does not require maintenance interventions.

Options on request:

  • colour anodization;
  • worm hollow shaft;
  • arrangement for trapezoidal screw, maximum dimensions Tr18x4.

Jack Stainless Steel

As a product of excellence, we present the jack TR32 also in stainless steel AISI 316: every surface in contact with the outside is made of this material, even the worm, because while working inside the carter (and therefore in an environment protected) it comes out. Stainless steel AISI 316 is optimal for resistance to corrosion and for compliance with standards of food companies. The couple responsible for the transmission of motion, works in oil bath and all the Trevi by Sir jacks are supplied complete with lubricant and thanks to the executive cure, do not require topping up to the entire product life cycle.

High-end jack, for applications where it is necessary high efficiency and endurance.

Standard configuration:

  • monoblock carter, anticorodal and anodized aluminium;
  • silver colour;
  • screw with dual output, solid shaft;
  • Inserting bushing, for a better trapezoidal rod guide
  • cap in anticorodal and anodized aluminium, for the total protection of the wheel;
  • worm with ground profile, in hardening steel;
  • bronze wheel;
  • supplied already filled with oil, for eternal lubrication: it does not require maintenance interventions.

Options on request:

  • colour anodization;
  • worm hollow shaft;
  • arrangement for trapezoidal screw, maximum dimensions Tr20x4;
  • version steel AISI 316.
