The 6308-2RS is a robust, single-row deep groove ball bearing engineered to deliver superior load-carrying capacity and extended service life in demanding environments. Equipped with tight-fitting, dual contact rubber seals (2RS), this model provides an impenetrable barrier against moisture, heavy dust, and external contaminants while securely retaining its factory-filled lubrication. Built to exact metric dimensions—a 40 mm bore, 90 mm outer diameter, and 23 mm width—the 6308-2RS is the definitive mechanical solution for medium-to-heavy industrial machinery, automotive hubs, and high-torque electric motors.

The 6306-2RS is a robust, high-precision single-row deep groove ball bearing engineered for exceptional endurance in medium-to-heavy mechanical setups. Unlike metal-shielded models, this bearing is equipped with synthetic rubber seals (2RS) on both sides, which are securely bonded to the outer ring to form a reliable contact seal against the inner ring. This design offers superior defense against water splashes, moisture, and fine dust particles while effectively retaining the internal factory grease. Featuring standard metric dimensions—a 30 mm bore, 72 mm outer diameter, and 19 mm width—the 6306-2RS serves as a highly dependable component for electric motors, agricultural equipment, and heavy industrial machinery.

The 6302-ZZ stands as a highly versatile, dual-metal-shielded single-row radial ball bearing engineered to deliver exceptional performance under elevated operational speeds and steady radial loads. To minimize drag, this model incorporates twin non-contact pressed steel shields (ZZ) that form a precise barrier over the internal mechanics, retaining factory-applied grease and deflecting dust without creating mechanical friction. Featuring standardized metric dimensions—a 15 mm bore, 42 mm outer diameter, and 13 mm width—the 6302-ZZ provides a highly dependable mechanical solution for power tools, electric motors, and automotive sub-assemblies.

The 6303-2RS represents a highly versatile, single-row radial bearing crafted for exceptional durability and uncompromising contaminant resistance. Outfitted with twin synthetic rubber seals (2RS) that make physical contact with the inner ring, this model securely locks in the factory-applied lubricant while creating a formidable barrier against water, dirt, and industrial grime. Manufactured to standard metric measurements—featuring a 17 mm bore, 47 mm outer diameter, and 14 mm width—the 6303-2RS is an indispensable component for power transmission systems, high-speed power tools, and automotive auxiliaries where reliability is paramount.

The 6301-ZZ stands out as a highly reliable, dual-metal-shielded single-row radial ball bearing engineered to deliver smooth rotational agility under high-frequency conditions and steady radial forces. To minimize power loss, this model incorporates twin non-contact pressed steel shields (ZZ) that form a precise gap over the internal elements, successfully locking in factory-applied grease and deflecting micro-particulates without introducing frictional resistance. Featuring standard metric dimensions—a 12 mm bore, 37 mm outer diameter, and 12 mm width—the 6301-ZZ provides a perfect mechanical solution for compact power tools, small electric motors, and modern appliance hardware.
