Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, while the standard PRS Bearings PRF180 meets ISO P0 (ABEC-1) levels, PRS Bearings also manufactures high-precision variants in P6 (ABEC-3) and P5 (ABEC-5) for applications requiring minimal runout and extreme rotational accuracy.
PRS Bearings provides the PRF180 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.
Engineered for heavy-duty endurance, the PRS Bearings PRF180 offers a dynamic load rating (Cr) of 33.615 and a static load rating (Cor) of 94,124. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
The PRS Bearings PRF180 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PR Radial Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 457.2 mm bore interface.
