The 6005-2RS is a versatile, light-series single-row radial ball bearing engineered to deliver smooth rotational performance where installation space is limited but reliable operation is essential. Differing from open configurations, this model incorporates dual contact synthetic rubber seals (2RS) that provide an exceptional defensive barrier against dust, moisture, and fine grit while securely locking in the factory grease. Standardized to metric dimensions—featuring a 25 mm bore, 47 mm outer diameter, and 12 mm width—the 6005-2RS offers the ultimate mechanical solution for mid-sized electric motors, power tools, and high-efficiency automotive components.

The 6004-2RS is a high-grade, single-row radial ball bearing designed to supply dependable operational stability and efficient friction reduction across medium-duty setups. Distinct from open configuration components, this unit utilizes dual-sided synthetic rubber contact closures (2RS) to forge an impenetrable physical boundary against ambient moisture, particulate matter, and fine debris while securely sealing the internal lubricant. Complying with standard metric scaling—featuring a 20 mm bore diameter, 42 mm outer diameter, and 12 mm width—the 6004-2RS stands as a versatile mechanical assembly for compact power tools, light vehicle hubs, and household appliances.

The 6002-2RS is a robust, highly versatile metric ball bearing engineered for applications where contamination control and sustained durability are critical. Fitted with twin synthetic rubber contact seals (-2RS), this component effectively locks in the factory-applied lubricant while blocking out moisture, dust, and abrasive particulates. Featuring a 15mm bore, a 32mm outer diameter, and a 9mm width, the 6002-2RS serves as an indispensable solution for electric motors, outdoor power equipment, and fluid pumps that operate in challenging conditions.

The 6000-2RS is a premium, rubber-sealed ball bearing engineered for environments where protection against moisture, dust, and contaminants is absolutely vital. Equipped with dual-sided synthetic rubber contact seals (2RS), this bearing actively blocks external particulate entry while keeping vital factory grease enclosed, ensuring a significantly longer service life in harsh conditions. Featuring a 10mm bore, 26mm outer diameter, and 8mm width, the 6000-2RS serves as a rugged, dependable component for electric powertrains, agricultural gear, and everyday mechanical assemblies.

The 608-2RS is an incredibly versatile, highly durable deep groove ball bearing recognized globally as the industry standard for a massive variety of applications. Measuring 8mm in bore diameter, 22mm in outer diameter, and 7mm in width, this bearing is engineered to deliver reliable radial load support while excelling in environments prone to contamination. Equipped with twin synthetic rubber seals (2RS) that make physical contact with the inner ring, the 608-2RS expertly locks in premium lubricating grease while locking out moisture, dust, and abrasive particles.

The 608 Open is a highly versatile, single-row deep groove ball bearing engineered for applications that require unhindered rotation and easy access for continuous lubrication. Manufactured without shields or seals, this "open" configuration eliminates all seal-induced contact friction, allowing for the absolute maximum rotational speed. With an industry-standard 8mm bore, a 22mm outer diameter, and a 7mm width, the unshielded 608 is the go-to structural component for high-speed electric motors, household appliances, and industrial power tools operating in clean environments.

The 606 Open is a precision-engineered, unshielded deep groove ball bearing designed specifically for applications where maximum rotational speed and unrestricted lubrication flow are required. With a 6mm bore, a 17mm outer diameter, and a 6mm width, this compact bearing operates without any seals or metal shields. This exposed design completely eliminates closure friction, allowing the 606 Open to achieve extraordinary RPMs while making it incredibly easy to continuously relubricate in oil-bath systems or enclosed gearbox housings.

The 6001-ZZ is a highly versatile, precision-engineered extra-light radial ball bearing optimized for medium-speed applications where dependable performance and compact dimensions are required. Equipped with dual non-contact metallic shields (ZZ), this bearing safely encapsulates premium factory-loaded lubricant while blocking fine dust and external particulate matter from entering the raceways. With its practical 12mm bore, 28mm outer diameter, and 8mm width, the 6001-ZZ serves as an industrial-grade solution for electric motor rotors, domestic appliances, and automated machinery demanding smooth, uninterrupted mechanical motion.
