About Metric Ball Bearings

Metric ball bearings are the most common bearings in machinery: single row deep groove (Conrad) radial bearings sized in millimeters. They carry radial loads and moderate thrust loads in either direction, and most sizes come open, with metal shields (ZZ) or with rubber seals (2RS).

Choose a series by the space you have and the load:

6000 series: extra light duty and compact
6200 series: light duty, the most widely used
6300 series: medium duty, with larger balls for heavier loads
6700 series, 6800 series and 6900 series: thin section bearings for tight spaces
16000 series: same bore and outside diameter as the 6000 series, but narrower

Suffixes on the part number describe closures and options, such as 2RS (sealed both sides), ZZ (shielded both sides), NR (snap ring) and C3 (more internal clearance than standard).

We also stock metric series bearings with special inch bores. You will find these in Odd Size Bearings.

Need a bearing you never have to regrease? Our sister store Solid Oil Bearings fills the 6000, 6200, 6300, 6700, 6800 and 6900 series with solid oil to order, so there is no grease to purge or wash out and nothing to relubricate.
