Looking for a Reliable 6307 Deep Groove Ball Bearing? Here's What Matters
Many industrial buyers face challenges with bearing procurement—whether it's finding the exact dimensions (35x80x21mm) for a critical machine, ensuring the seal type (ZZ or 2RS) matches the operating environment, or dealing with suppliers who can't verify product authenticity. These issues often lead to installation delays, unexpected equipment downtime, or premature bearing failure.
Built for Reliable, Long-Term Performance
The 6307 deep groove ball bearing addresses these pain points through precision engineering and versatile design. As a specialized supplier with access to comprehensive bearing ranges, we ensure this SKF 6307 bearing meets original manufacturer specifications, including its 35mm bore, 80mm outer diameter, and 21mm width. Suitable for both radial and light axial loads, it performs consistently in wind power generators, automotive transmissions, and industrial machinery—applications where reliability directly impacts operational efficiency.
Where This Bearing Performs Best
This 6307 bearing excels in moderate-speed, high-load environments with operating temperatures compatible with standard industrial conditions. The ZZ metal seals provide effective protection against dust and debris in dry applications, while the 2RS rubber seals offer enhanced moisture resistance for wetter environments. Its single-row, non-aligning design makes it ideal for systems with minimal shaft misalignment, such as electric motor assemblies and conveyor rollers.
Engineering Details That Matter
The 6307 bearing's performance is rooted in critical engineering features. Constructed from high-grade bearing steel, it delivers excellent hardness and wear resistance, ensuring longevity under cyclic loads. Precision ratings from P0 to P4 allow customization based on application requirements—P5 or P4 grades for high-speed machinery where vibration control (Z2V2 or Z3V3) is essential. The unseparated design simplifies installation and maintenance, while the 0° contact angle optimizes radial load capacity, a key factor in reducing premature fatigue in industrial gearboxes.
Why Bearing Selection Affects Total Cost
Choosing the right 6307 bearing directly impacts total cost of ownership. A bearing with incorrect precision or seal type may fail prematurely, leading to unplanned downtime, replacement costs, and potential damage to adjacent components. For example, using an open bearing in a dusty wind power application could result in abrasive wear, reducing service life by 50% or more. By selecting the appropriate 6307 ZZ 2RS bearing variant and ensuring material quality, users avoid these hidden costs and extend equipment service intervals.
