The 6016-2RS is a heavy-duty Deep Groove Ball Bearing designed for challenging operating environments where superior contamination resistance is critical. Equipped with dual rubber contact seals (2RS) on both sides, this bearing offers exceptional protection against moisture, fine dust, and liquid splash, making it far superior to shielded variants in wet or dirty conditions. With an 80 mm bore, 125 mm outer diameter, and a robust 22 mm width, the 6016-2RS is engineered to handle substantial radial loads while maintaining stability in demanding industrial settings.

The 6016-ZZ is a precision-engineered Deep Groove Ball Bearing optimized for applications demanding minimal rotational resistance alongside reliable contamination defense. Featuring dual non-contact pressed steel shields (ZZ), this bearing effectively blocks dust, dry particulates, and airborne debris while maintaining exceptionally low friction torque. With an 80 mm inner diameter, 125 mm outer diameter, and 22 mm section width, the 6016-ZZ delivers robust radial load capacity in a standardized ISO 60 Series footprint, making it ideal for high-speed industrial drives where efficiency and heat management are priorities.

The 6017-2RS is a robust Double Rubber-Sealed Deep Groove Ball Bearing designed for medium to heavy-duty industrial applications requiring superior contamination protection. Fitted with two high-quality rubber contact seals (2RS) on both sides, it provides excellent defense against dust, moisture, and debris while retaining lubrication for extended service life. With an 85 mm bore, 130 mm outer diameter, and 22 mm width, this bearing delivers reliable performance in electric motors, gearboxes, and industrial equipment where operational dependability and environmental sealing are critical.

The 6017-ZZ is a Double Metal-Shielded Deep Groove Ball Bearing designed for medium to heavy-duty industrial applications requiring reliable performance with minimal maintenance. Fitted with two pressed steel shields (ZZ) on both sides, it effectively retains lubrication while permitting higher operational speeds compared to contact-sealed variants. With an 85 mm bore and standard 22 mm width, this bearing delivers robust performance for electric motors, gearboxes, and industrial equipment where contamination resistance and speed capability are critical.

The 6018 is an Open-Type Deep Groove Ball Bearing engineered for applications requiring maximum flexibility in lubrication and sealing arrangements. Without integrated seals or shields, this bearing design allows for customized grease selection, relubrication intervals, and external sealing solutions tailored to specific operating conditions. Featuring a 90 mm bore and 24 mm width, the 6018 open configuration is ideal for large electric motors, industrial gearboxes, and heavy machinery where maintenance accessibility and optimized lubrication management are priorities.

The 6018-2RS is a Double Rubber-Sealed Deep Groove Ball Bearing specifically engineered for demanding operating conditions where superior contamination exclusion and moisture resistance are essential. Equipped with two NBR rubber contact seals (2RS) on both sides, this bearing provides exceptional protection against dust, water spray, and fine particulate matter while retaining high-quality grease lubrication throughout extended service intervals. With a 90 mm bore diameter and 24 mm width, the 6018-2RS delivers reliable performance for agricultural machinery, outdoor equipment, and industrial applications exposed to challenging environmental conditions.
