Bearing range
Bores from 1.5 mm to 9 mm for instruments, small motors, dental handpieces and RC models.
Miniature bearings are small deep groove ball bearings with a bore under 10 mm. In these sizes a single millimetre is the difference between the right part and a useless one, so we check every dimension before we quote. The most common of all is the 608 (8 × 22 × 7 mm), found in power tools, skateboards, 3D printers and small fans.
Small in size but made to tight tolerances. We stock open, shielded and sealed miniatures in chrome steel and stainless, including flanged versions.
