The S6203-2RS is a premium, single-row deep groove ball bearing engineered specifically for harsh, corrosive environments. Manufactured from high-grade stainless steel rather than standard chrome steel, this bearing provides exceptional resistance to rust, moisture, and chemical exposure. Featuring dual Nitrile Butadiene Rubber (NBR) seals, it securely locks in high-quality grease while keeping out water and particulate matter. With standardized dimensions of a 17mm bore, 40mm outer diameter, and 12mm width, the S6203-2RS delivers a reliable, long-lasting solution for washdown and outdoor applications.

The 6203 Open is a versatile, light-series ball bearing designed for applications requiring maximum rotational speed and efficient heat dissipation. Unlike sealed variants, this open-type configuration features no contact seals or shields, allowing for minimal friction torque and the ability to utilize external lubrication systems tailored to specific operating conditions. With a compact 17mm bore, 40mm outer diameter, and 12mm width, it serves as a critical component in electric motors, household appliances, and automotive accessories where the housing provides sufficient environmental protection.

The 6203-2RS is a highly versatile, medium-duty rotational component engineered for mechanical systems exposed to moderate contamination. Equipped with twin synthetic rubber seals (2RS), this bearing establishes a tight, protective boundary that aggressively blocks out moisture, ambient dust, and operational debris. Featuring a standard 17mm bore alongside a 40mm outer diameter, the 6203-2RS is the optimal selection for fractional horsepower motors, automotive alternators, and household appliances where sustained, maintenance-free performance is required.

The 6203-ZZ is a Double-Shielded Deep Groove Ball Bearing engineered for reliable performance in electric motors and general industrial applications. Featuring the standardized deep groove raceway geometry, this bearing efficiently accommodates moderate radial loads and bidirectional axial loads in space-constrained assemblies. With a 17 mm bore, 40 mm outer diameter, and 12 mm width, it offers a balanced cross-section suitable for various mechanical housings. Equipped with double metal shields (ZZ) for effective contamination resistance while maintaining low friction operation, it is an ideal choice for applications requiring extended service life with minimal maintenance intervention .

The 6203-Z is a Single-Shielded Deep Groove Ball Bearing designed for reliable performance in light industrial equipment and drive systems. Featuring the standard deep groove raceway geometry, this bearing effectively accommodates moderate radial forces and light axial loads in both directions. With a 17 mm bore, 40 mm outer diameter, and 12 mm width, it provides a robust cross-section suitable for compact machinery housings. Equipped with a single metal shield (Z) on one side for contamination resistance while maintaining accessibility for re-lubrication, it is an excellent choice for applications requiring balanced protection and maintenance flexibility .

The 6203-2RZ is a Double Rubber-Sealed Light Series Deep Groove Ball Bearing engineered for applications requiring effective sealing and reliable performance in limited spaces. Fitted with two low-friction rubber seals (2RZ) on both sides, it provides excellent protection against dust, moisture, and particulate ingress while retaining lubricant efficiently. With a 17 mm bore and a compact 12 mm width, this bearing is well-suited for small motors, precision gearboxes, and light industrial equipment where environmental resistance and smooth running are vital.
