6300-2RS Medium-Duty Deep Groove Ball Bearing Sealed For Industrial Motors & Pumps | 10×35×11 mm

Part of the robust 63 dimension series, the 6307-2Z ball bearing is engineered with a thicker cross-section to accommodate heavier load requirements than its 62 series counterparts. Featuring boundary dimensions of 35 mm (bore), 80 mm (outer diameter), and 21 mm (width), this bearing is enclosed on both sides with non-contact metal shields (-2Z or ZZ). This shielded architecture effectively prevents the ingress of dust, dirt, and metallic debris while retaining the internal lubricant, making it an ideal maintenance-free solution for industrial environments.

The 6307-2RS is a robust, single-row radial bearing designed for demanding environments where both high load capacity and superior sealing are critical. Featuring a 35 mm bore, 80 mm outer diameter, and 21 mm width, this 63-series bearing is equipped with contact rubber seals (2RS/RS) on both faces. These reinforced seals act as a physical barrier against liquid splashes and fine abrasive dust, ensuring the internal raceways remain pristine during heavy-duty operation in outdoor or industrial settings.

The 6307 is a robust single-row deep groove ball bearing engineered for medium-duty rotating equipment that demands consistent performance under continuous load. Built to the ISO 63 medium series, this component balances a 35 mm bore with a 21 mm cross-section, making it a preferred choice for industrial drives, conveyor systems, and heavy-duty electric motors. Welink Bearing manufactures this series to strict dimensional tolerances, ensuring reliable operation in demanding mechanical environments where uptime and load capacity are critical.

The B17-99-2RS is a specialized, heavy-duty single-row deep groove ball bearing tailored predominantly for high-stress automotive electrical systems and demanding industrial components. Recognized for its unique, wider cross-section relative to standard bearings, this model excels at absorbing severe belt tensions and radial loads. Equipped with dual advanced Nitrile Butadiene Rubber (NBR) contact seals, it effectively isolates the internal rolling elements from engine grime, road salt, and moisture. Boasting a 17mm bore, 52mm outer diameter, and a robust 17mm width, the B17-99-2RS is the industry benchmark for rebuilding alternators and high-output generators.

The 6314-2RS is a robust, heavy-series metric deep groove ball bearing built specifically to endure demanding industrial environments and high-load applications. Equipped with heavy-duty dual contact rubber seals (2RS), this model provides superior defense against moisture, dirt, and heavy particulate contamination. Measuring 70 mm in the bore, 150 mm in outer diameter, and 35 mm in width, the 6314-2RS is an indispensable mechanical component for large-scale electric motors, heavy automotive transmissions, and rugged agricultural machinery requiring maintenance-free reliability.

The 6310-2RS is a robust, medium-series deep groove ball bearing specifically engineered to accommodate substantial radial and axial loads in demanding industrial environments. Unlike miniature or thin-wall models, this heavy-duty bearing features thick cross-sections and large rolling elements, making it an absolute powerhouse for rigorous applications. Outfitted with dual contact rubber seals (2RS), it forms an impenetrable barrier against harsh contaminants, water ingress, and abrasive dust. With standardized metric dimensions—a 50 mm bore, 110 mm outer diameter, and 27 mm width—the 6310-2RS delivers unyielding structural integrity for heavy machinery, automotive transmissions, and large-scale industrial motors.

The 6309-2RS is a high-end, mid-sized heavy metric deep groove ball bearing engineered to deliver balanced load capacities and exceptional structural rigidity in harsh working conditions. Fitted with dual-lip synthetic rubber contact seals (2RS), this bearing offers an impermeable barrier against airborne grit, moisture, and fine particulates. Featuring a 45 mm bore, 100 mm outer diameter, and 25 mm width, the 6309-2RS represents the ideal mechanical solution for medium-to-large rotating machinery, industrial pumping systems, and heavy-duty electric power drives requiring long-term, maintenance-free operation.

The 6300-2RS is a robust, single-row deep groove ball bearing manufactured to deliver consistent load-bearing capability in demanding mechanical environments. Distinguished by its dual-contact rubber seals (2RS), this component offers exceptional ingress protection, effectively locking in factory-filled grease while blocking out water, mud, and abrasive particulates. With a 10mm bore and a substantial 35mm outer diameter, the 6300-2RS is an integral solution for electric motors, heavy-duty power tools, and agricultural equipment that require prolonged service life under harsh operating conditions.
