120 mm 80 mm PA8020 Frequently Asked Questions about PA8020 Metric Series Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PA8020 is designed for rigid configurations. For optimal performance, strict alignment of the 80 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
PRS Bearings recommends storing the PA8020 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.
Yes, while the standard PRS Bearings PA8020 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 PA8020 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.
