DOUBLE ROW BALL BEARING MRC(SKF) 5209SBKFF
The MRC (SKF) 5209SBKFF is a double-row angular contact ball bearing designed for applications requiring high radial load capacity, axial load support in both directions, and rigid shaft positioning. It belongs to the MRC legacy 5200 Series, widely used in pumps, electric motors, conveyors, agricultural machinery, and industrial equipment.
The SBKFF suffix is an older MRC designation commonly associated with a double-shielded version of the 5209 family. This makes it suitable for applications needing retained lubrication and reduced contamination. Cross-reference sources list MRC 5209-SBKFF among modern equivalents.
MRC is a respected industrial bearing brand within the SKF group.1200
