6304 ZZ SKF 20x52x15 - Ball Bearing

Ball bearing with metal shields for high-speed operation

SKF Explorer technology for increased durability

Reliable solution for industrial bearing housings

Main Description

6304 ZZ SKF 20x52x15 is a single-row deep groove ball bearing engineered for demanding industrial applications where high reliability, stable performance, and long service life are essential. As part of the robust 6300 series and manufactured in SKF Explorer class, this bearing delivers improved load capacity and extended operating life compared to standard designs.

The bearing is equipped with double-sided ZZ metal shields, providing effective protection against dust and light contamination while remaining non-contact in operation. This design allows low rolling resistance and supports high rotational speeds, making the bearing suitable for continuous and variable-speed operation. Factory-filled grease ensures long-lasting, maintenance-free performance.

With a dynamic load rating of 16.8 kN and a static load rating of 7.8 kN, the 6304 ZZ SKF bearing reliably handles radial loads and moderate axial loads in both directions. The standard CN internal clearance ensures stable operation under typical mounting conditions and temperature ranges. A precision steel cage provides accurate ball guidance, smooth rotation, and low noise levels.

The bearing can be used as a standalone bearing unit or installed in a standard bearing housing, offering flexibility in machine design and maintenance. Typical applications include electric motors, pumps, fans, gearboxes, conveyors, and industrial drive systems where high durability and predictable performance are required.

Manufactured by SKF, this bearing meets strict industrial quality standards and is trusted by B2B customers for production, maintenance, and equipment refurbishment.
