NTN Bearings

In testing the NTN bearings are generally the best irrespective of which seal is put on them. Their technical support is also very good (especially in the UK).

The vast majority of NTN's 6000 series bearings are made in Japan and they are sticklers for quality control. The only issue with NTN is supply.
