Industrial NR 1641DC Radial Deep Groove Ball Bearing

Boston Gear NR 1641DC radial deep groove ball bearing is a precision single‑row bearing with a 1.0000 in bore, a 2.0000 in outer diameter, and a width of 0.5625 in. It uses a straight bore and double seals (DC) on both sides and is specified as without a snap ring. This radial deep groove design supports smooth, low‑friction rotation in inch‑size assemblies and is commonly used where a compact bearing footprint is required in industrial equipment. The 1641DC is part of Boston Gear’s RRX family, aligning with inch‑series housings and components that accommodate a 1 in bore. Seals on both sides help retain lubricant and exclude contaminants, contributing to stable performance in repetitive or continuous operation. The combination of precise bore and outer diameter tolerances, along with double sealing, makes the 1641DC a straightforward, drop‑in replacement for OEM bearings that require an identical footprint and seal configuration, ensuring reliable durability in conveyors, packaging lines, and general machinery where axial loads are managed by adjacent components and radial load is carried by the inner and outer race. The bearing’s dimensions—1.0000 in ID, 2.0000 in OD, 0.5625 in width—define its compact form factor, enabling it to fit into small‑to‑mid‑sized mechanical assemblies without sacrificing rigidity or precision.
