The FAG QJ309-XL-MPA is a four-point contact ball bearing from the QJ3 series, designed for high radial loads and single-direction axial load capacity in space-saving arrangements. This bearing features an extra-light (XL) design with a machined brass cage guided on the outer ring (MPA), and an open (unsealed) configuration suitable for use with external lubrication systems. Manufactured from high-grade bearing steel and supplied in original factory-sealed packaging, it is intended for demanding industrial environments. Typical applications include electric motors, pumps, gearboxes, agricultural machinery, and general industrial equipment where precise shaft positioning and combined load handling are required.
