PAG180 25.4 mm 508 mm 457.2 mm Frequently Asked Questions about PAG180 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Certainly. While the standard PAG180 is pre-filled with high-grade industrial lubricant, PRS Bearings can provide custom fills, including food-grade (NSF H1), high-temperature, or extreme-pressure greases tailored to your operational needs.
PRS Bearings provides the PAG180 with various cage options including high-strength pressed steel, machined brass for high-vibration tasks, or reinforced polymers for the quietest operation in precision machinery.
Depending on your thermal and fit requirements, PRS Bearings supplies the PAG180 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
Thanks to its robust 57,373 dynamic load capacity, the PRS Bearings PAG180 is highly sought after in mining, metallurgy, agricultural machinery, and heavy industrial gearboxes where operational reliability is paramount.
