Extra thin bearings mean a extremely thin bearing section, they are designed for applications where space limitations are of the utmost importance.It realizes the miniaturization and lightweight of the products. The inner ring and outer ring has been minimized or thinned out as more as possible,of course the disadvantage is that this comes at the expense of load capacity.

Runstar Bearing has a full dimention of extra thin bearings(6700ZZ,6800ZZ,6900 Series) for choice, the precision tolerance is from ABEC-1 to ABEC 9 for choice, the material is chrome steel(Gcr15) or stainless steel(440 or 420) at request, custom-made products is accepted in Runstar. All Runstar’s Bearings are strictly controlled under ISO9001:2015.
