6324 Heavy-duty Single-Row Deep Groove Ball Bearing For Large-Scale Industrial Machinery | 120×260×55 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 6304-ZZ is a heavy-wearing, medium-duty Deep Groove Ball Bearing constructed with twin stamped steel closures (ZZ). Engineered to strike the perfect balance between high-speed rotational capability and robust load support, this bearing is an essential component for continuous-running machinery. Measuring 20 mm for the inner bore, 52 mm across the outer diameter, and featuring a 15 mm width, it belongs to the ISO 6300 series. This classification means it features larger internal rolling elements and a thicker raceway cross-section than standard light-duty alternatives, granting it exceptional resilience under substantial radial and moderate axial stresses.

The 6304-2RS is a rugged, medium-duty Single-Row Deep Groove Ball Bearing equipped with dual synthetic rubber contact closures. Built specifically to isolate the internal rolling elements from severe environmental contamination, this bearing excels in operational zones where water, mud, and fine particulate matter are a constant threat. Possessing a 20 mm inner bore, a 52 mm outer diameter, and a 15 mm thickness, it complies with the ISO 6300 dimensional standard. This bulkier geometric profile guarantees superior shock resistance and elevated radial weight-bearing capacity when measured against standard light-duty alternatives of the same bore size.

The 6304 is an unsealed, premium-grade Single-Row Deep Groove Ball Bearing engineered for integration inside secure, enclosed mechanical housings. By entirely omitting side shields and rubber seals, this bearing offers unhindered access to its internal rolling elements, maximizing the flow of external lubricants. With precise metric dimensions of a 20 mm bore, a 52 mm outer diameter, and a 15 mm width, it is categorized under the medium-duty ISO 6300 series. This beefier structural profile provides significantly higher radial and axial load-bearing capabilities than lighter 6000 or 6200 series alternatives of the same bore size.

The 6302-2RS is a premium-grade, Double Rubber Sealed Single-Row Deep Groove Ball Bearing designed for superior protection in demanding environments. Optimized for high-torque applications and heavy-duty machinery, it employs dual contact seals (2RS) to lock in high-quality lubricant while providing an airtight defense against moisture, dust, and grime. With its 15 mm bore, 42 mm outer diameter, and 13 mm width, this bearing belongs to the 6300 "Medium" ISO series, offering significantly higher load-bearing capacity compared to light-duty alternatives.

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.
