19.05 mm 266.7 mm 228.6 mm PRF090 Frequently Asked Questions about PRF090 PR Radial Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PRF090 is designed for rigid configurations. For optimal performance, strict alignment of the 228.6 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 23,380 dynamic load capacity, the PRS Bearings PRF090 is highly sought after in mining, metallurgy, agricultural machinery, and heavy industrial gearboxes where operational reliability is paramount.
The PRS Bearings PRF090 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 228.6 mm bore interface.
PRS Bearings recommends storing the PRF090 in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
