SW 6210-ZZ Deep Groove Ball Bearing - 50x90x20mm - Shielded Steel - High Performance Industrial Replacement
The SW 6210-ZZ is a heavy-duty, single-row deep groove ball bearing engineered for high radial and moderate axial loads in demanding industrial environments. Featuring a standard bore of 50mm, an outer diameter of 90mm, and a width of 20mm, this bearing utilizes two non-contacting metal shields ('ZZ' designation) designed to retain high-quality internal lubricant while preventing the ingress of coarse contaminants like dust and debris. Constructed from robust SAE 52100 chrome steel, the 6210-ZZ provides exceptional fatigue life, achieving a high dynamic load rating (Cr) of 34.5 kN, making it ideal for continuous operation in high-cycle machinery where reliability is paramount.
SW bearings are manufactured to tight P6 precision tolerances, ensuring low noise operation and reduced frictional heat generation, crucial for applications involving high rotational speeds (up to 7,000 RPM with grease lubrication). The pre-lubricated design simplifies installation and eliminates the need for initial greasing, reducing maintenance complexity and total cost of ownership (TCO). This bearing is the preferred choice for replacement in electric motors, power transmissions, industrial fans, pumps, and gearboxes where dimensional stability and prolonged service life are non-negotiable requirements.
