Bearings for 3D Printer

Why do I need bearings?

Regardless of the kinds and types of bearings that are used in CNC machines and 3D printers, they are all designed for the same purpose - to ensure the accuracy of movement when performing work.

The use of bearings reduces friction and sliding forces, reduces the load on power units and working bodies, and significantly increases the life of the equipment as a whole.

Use of bearings

When assembling CNC machines, 3D printers and other devices where there are guides and moving parts, bearings of different kinds are used.

The main types of bearings that are used in CNC machines and 3D printers:

• Friction bearings of standard design;
• Friction bearings with a concave outer race (for belt drives and for use with guide rails or shafts);
• Linear bearings (for linear guide rails and shafts);
• Support bearing (support roller);
• Fish-eye end bearings.

Some types of bearings are easy enough to install and fix on a shaft or other part (rolling bearings, thrust bearings), other types are very demanding to be positioned correctly (linear bearings).

At the same time, all types of bearings have these useful properties:

• They can easily withstand the maximum allowable loads;
• In any situation are able to provide softness and smoothness of movement without seizures and vibrations;
• When working do not create noise;

Bearings maintenance

All bearings must be clean and lubricated to ensure smooth movement of any machine tool. Debris getting inside the bearing, or lack of lubrication will shorten the life of any bearing many times over.

Maintaining any kind of bearing is fairly easy. Just keep the bearing clean and lubricate it periodically. With proper and regular maintenance, you will maximize their life span.

If you notice a suspicious sound in the work of the machine, if you notice jerks in the work - first of all check the bearings. If there is backlash, sticking, squeaking when rotating - the bearing should be replaced immediately. This is extremely important, because even one bad bearing can affect the entire operation of the 3d printer, as well as put out of action the rest of the supporting mechanisms.
