Motion components

Parts for 3D printers are essential for the correct functioning of the entire mechanism. Wheels, washers, springs and blocks - each part plays an important role in the correct functioning of the machine. Parts for 3D printers available in Solectroshop's offer include both modern technological solutions and replacement elements. Bearings, heads, extruders and pinions - we provide you with everything you need. Parts for 3D printers from Solectroshop are products that are perfectly adapted to the needs of advanced devices. In our product range you will find not only the necessary equipment to optimise the control of your 3D printing machines, but also mechanical parts that are especially important for the service life of your machine.

Motion components


  • Mechanics

    Mechanical accessories and elements of 3D printers that are essential to its functioning. In this category, you will find belts, springs, supports and many other small elements your printer won´t work without

  • Chains

    In FDM printers hanging cables are often exposed to range of external factors that can severely impact the condition of the cable. For that very reason, cable protectors can be used to save the cable from any negative effects. In our offer you can find, different dimensions of protectors to fit any of you potential requirements

  • Couplers

    Couplers are 3D printer parts that connect the motor to the spindles. Couplers are usually made of aluminium. Their most important feature is their dimensions, so different printers have very different parameters. In our offer we have flexible couplers from 5x5mm to 10mm, pneumatic connectors and much more. See the offer below and our content pages if you have any questions.

  • Spindles

    Spindles are the essential parts of every 3D printer. They are long screws whose first applications date back to presses and milling machines. It provides the specific mechanism of operation for vertical movement of 3D printers. It also includes the nut that is screwed on its linear axis when the spindle rotates. In our offer we have trapezoidal spindles of various dimensions. Please contact us if you have any questions

  • Pulley

    Pulleys, like spindles and couplers, are essential elements of a 3D printer's motion mechanism. Pulleys are traction devices that transmit force. The most basic example of pulleys is seen in cranes. In a 3D printer, pulleys play the same role. As with other motion components, it is very important to select a pulley that matches the rest of your 3D printer. To do this, check the number of teeth, bore dimensions and outside diameter so that the pulley matches the belt you use.

  • Bearings

    Bearings are an integral part of a 3D printer and work in conjunction with couplers. They are necessary to reduce friction when rotating the spindle. They are usually made of steel in the housing material and plastic in the inner bearing. Check out our offer of bearings with a variety of dimensions and shapes.

  • Wheels

    The wheels are used in 3D printers to ensure precision of movement. Find V-groove and double V-groove wheels in our offer and consult forum and content pages if you have questions.

  • Supports

    Wide range of linear shaft holders from 8mm to 12mm for a variety of printers including Reprap Varilla printers.
