Accessories and Engines


It is a mechanical element that reduces the friction between an axle and the parts connected to it by means of rolling elements that are inside, which serves as support to transmit the loads while facilitating its rotation.


The rotating element that can be used in the manufacture of the bearing can be balls, rollers or needles. The bearings can also be classified according to the direction of stress that it supports: axial, radial or a combination of both.


The radial type is the one that supports radial stresses, which are efforts in the direction normal to the direction that passes through the center of its axis (like a wheel), the axial type is if it supports efforts in the direction of its axis (like a hinge ); and axial-radial if both can support them.


Each bearing class shows characteristics that depend on its design and that make it more or less appropriate for each application.


Of the different types, the following stand out:

  • Deep groove ball bearing.
  • Axial ball bearing. (Single or double effect)
  • Cylindrical roller bearing (single or double row).
  • Tapered roller bearing
  • Needle roller bearings



The planetariums reduce the speed of the engines by increasing the output torque to the maximum. These can be supplied by us as a solution adapted to the needs of the customer for modules, together with the motor, as well as with pinions for crowns.


Depending on each case and customer’s need, different engine solutions are offered. The most commonly used would be the hydraulic ones (we work with a range of 25 to 400 cm3 / rev); electric DC motors with built-in reduction (giving the option to be supplied with or without encoder) and electric motors of alternating current that can be supplied with all types of reducers (most common ranges between 0.09 and 3Kw of power).

There is also the possibility of making designs of cranks or manual systems.
