Technical data and compatibility

SKF 6307 M C3 deep groove ball bearing 35x80x21 is a high-quality rolling bearing designed for demanding industrial applications where high durability, operational stability and reliable performance under increased thermal load are essential. This bearing belongs to the popular 6300 series and is widely used in electric motors, gearboxes, pumps and general machinery.

The C3 internal clearance allows safe operation at higher rotational speeds and elevated operating temperatures. It compensates for thermal expansion of the shaft and housing, ensuring smooth and stable bearing performance over long service intervals. The M brass cage provides excellent mechanical strength, improved guidance of rolling elements and enhanced resistance to wear in continuous-duty applications.

This deep groove ball bearing is suitable for carrying radial loads as well as moderate axial loads in both directions. It can be installed in standard bearing arrangements such as a bearing unit or bearing housing, making it a versatile solution for many machine designs used in industrial drives, compressors, fans and conveyors.

Manufactured by SKF, this bearing guarantees consistent quality, precise dimensional accuracy and long service life. The standardized dimensions 35x80x21 ensure easy replacement and broad compatibility with existing equipment.
