The MRC 6221-2ZR is a robust, single-row deep groove ball bearing engineered for demanding industrial applications requiring high speeds and excellent contamination protection. Part of the industry-standard 6200 light series, the 6221-2ZR features a precise 105mm bore, 190mm outer diameter, and 36mm width, offering an optimal balance of radial load capacity and compact size. The ‘-2ZR’ designation signifies double metal shields, providing effective retention of high-quality grease while substantially protecting the raceway from dust, debris, and splashes, ensuring longer service life and reduced maintenance intervals in harsh environments. Manufactured to ISO standards, this bearing provides high running accuracy and low friction, making it suitable for critical machinery.
Designed for maximum operational uptime, the 6221-2ZR is the ideal choice for high-reliability applications such as electric motors, gearboxes, centrifugal pumps, and heavy-duty conveyor systems. Its capacity to handle both significant radial loads and moderate axial loads in both directions makes it a versatile foundational component in power transmission assemblies. When purchasing this MRC product, clients secure a premium component synonymous with durability and consistent performance, minimizing unexpected downtime and lowering the total cost of ownership (TCO) compared to standard commodity bearings.
