220 mm 180 mm PA18020 Frequently Asked Questions about PA18020 Metric Series Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Depending on your thermal and fit requirements, PRS Bearings supplies the PA18020 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
The standard PRS Bearings PA18020 is designed for rigid configurations. For optimal performance, strict alignment of the 180 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
The PRS Bearings PA18020 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the Metric Series Bearing fits snugly against shaft shoulders, preventing stress concentration at the 180 mm bore interface.
Certainly. While the standard PA18020 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.
