Within linear motion applications, friction can be a “drag”, and can lead to serious problems relating to wear and tear, as well as consistent accuracy over an extended period of time. Fortunately, we humans are quite smart, and have developed specialised tools like these 608ZZ Radial Ball Bearings, which are designed to utilise rolling balls within enclosed chambers to drastically reduce the friction of moving parts.

These Radial Ball Bearings are built with an 8mm inner diameter, a 22mm outer diameter and a 7mm thickness, and are stocked specifically to cater to the classic Greg’s Wade Extruder that utilises three of them. However, because of the relatively simple design, they can be used for almost any radial motion applications that suit the ID, OD and thickness of these bearings.

  • Outer Diameter

– 22mm

  • Thickness

– 7mm


Typical Applications for these 608ZZ Radial Ball Bearings:

While these were originally stocked for the Greg’s Wade Extruder, 3D Printing has since moved on to much better, and more affordable, extruders like the E3D and MK variations. However, we still stock these to accommodate 3D Makers who may need them, but also for general Makers who can find a use for them. And thanks to the general sizing of these Bearings, they can actually be used for all sorts of radial motion applications, such as attaching Leadscrews to mounts or even attaching wheels to skateboards if that’s what you’re keen to do.
