Product Description

Timken Fafnir MM30BS62 DUH is a matched duplex pair of super precision ball screw support bearings, offered here from new-in-box original Timken/Fafnir packaging. The set carries part number MM30BS62 DUH and is manufactured in the USA. Each unit in the matched pair is stamped with MPN MM30BS62 DUH and lot number 31979, and the outer box label confirms ABEC 9-MMV precision, 100% tested per ABMA STD 13.

The set features a 30 mm bore, 62 mm outside diameter, and a combined set width of 30 mm. The 60-degree contact angle and universal duplex mounting arrangement suit these bearings for ball screw support applications in CNC machine tools and similar precision motion systems. The phenolic cage, open enclosure, heavy preload of 1,000 lbf, and ABEC 7 / ISO P4 precision class are confirmed from both the product label and authorized catalog data for this exact MPN.

Cross-reference identifiers associated with this MPN in OEM catalogs and precision bearing market listings include BSB030062, 30TAC62BSUC10PN7B (NSK designation), SAC3062AG (KOYO designation), and BSB030062-T (FAG designation). Buyers sourcing by any of these cross-references should confirm exact MPN and configuration before purchase.
