QJ 209 MA

Built to standard 45×85×19 mm metric dimensions with a 35° contact angle, the QJ 209 MA is a single-row four-point contact ball bearing designed specifically to handle heavy axial loads in both directions alongside moderate radial forces. Its split inner ring allows for a higher ball complement than conventional bearings, enabling the QJ 209 MA to deliver the axial capability of a double-row angular contact bearing while saving valuable axial space. Equipped with a solid machined brass cage centered on the outer ring (designated by the MA suffix), the QJ 209 MA maintains excellent structural stability and low friction at operating speeds reaching up to 14,000 rpm. Additionally, because the outer ring with the ball and cage assembly can be mounted separately from the two inner ring halves, assembling and inspecting the QJ 209 MA in tight industrial gearboxes, pumps, and indexing tables is straightforward and efficient.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
