Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PXG047 is designed for rigid configurations. For optimal performance, strict alignment of the 120.65 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Thanks to its robust 37,752 dynamic load capacity, the PRS Bearings PXG047 is highly sought after in mining, metallurgy, agricultural machinery, and heavy industrial gearboxes where operational reliability is paramount.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXG047 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
Under optimal lubrication conditions, the PRS Bearings PXG047 can reach a limiting speed of 2,090 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
