6302-2RS Sealed Deep Groove Ball Bearing | High-Performance Sealing | 15×42×13 mm

The 6305-ZZ is a high-load capacity radial ball bearing engineered for demanding mechanical environments. It is a core component for machinery requiring high rotational stability and durability under significant radial loads. Equipped with dual non-contact metal shields (ZZ), this bearing ensures that factory-packed lubrication is retained while preventing the ingress of dust and moderate debris without increasing frictional torque. With a 25mm bore and 62mm outer diameter, it serves as a robust solution for medium-sized electric motors, industrial pumps, and automotive drivetrains.

The 6305-2RS is a high-capacity, rubber-sealed deep groove ball bearing engineered for demanding industrial environments where debris exclusion and grease retention are paramount. Featuring a 25mm bore and a robust 62mm outer diameter, this model offers a superior balance between radial load rating and high-speed stability. The dual-lip contact seals (2RS) provide an airtight barrier against dust, moisture, and contaminants, making it a "lubricated-for-life" solution that eliminates the need for manual maintenance in inaccessible assemblies.

The 6305 is an unsealed, single-row deep groove ball bearing engineered specifically for enclosed industrial environments where maximum rotational speed and minimal friction are the top priorities. Featuring a completely open architecture without seals or shields, this bearing allows for the free flow of external lubricants directly into the rolling elements. With a 25 mm bore diameter, a 62 mm outside diameter, and a 17 mm width, it falls under the medium-duty ISO 6300 series, offering a thicker cross-section and significantly higher load-bearing capabilities than standard light-duty alternatives.

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.
