DDRI-1634 – DDRI Series Radial Shielded Miniature/ Instrumentation Ball Bearings

DDRI-1634 - DDRI Series Radial Shielded Miniature Instrumentation Ball Bearings

The DDRI-1634 bearing, a flagship member of the DDRI series, combines compact radial geometry with advanced shielding to fend off dust and moisture. Precision machining minimizes clearance, so the rings glide together almost without thought. A pair of metal shields locks out grit yet offers enough breathing room for the lubricant to circulate freely.
