Series Overview

Miniature ball bearings are NSK's extra-small/miniature bearing lineup defined in catalog CAT. No. E126h, covering a metric bore range of 1–9 mm with the same construction as standard deep groove ball bearings — carrying radial load plus moderate bidirectional axial load. This category complements Nahshon's existing deep groove ball bearing category (10–110 mm bore), serving selection needs in optical instruments, medical devices, OA equipment and small precision mechanisms.

Types & Seal Options

The metric series is primarily available in MR (thin-wall) and 6xx (standard-wall) base types, with open, double-shielded (ZZ) and contact rubber seal options depending on dust/moisture protection needs.
