Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings recommends storing the PAA047 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 PAA047 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.
Every PRS Bearings PAA047 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 120.65 mm bore and 133.35 mm outer surfaces remain pristine during overseas transit.
The standard PRS Bearings PAA047 is designed for rigid configurations. For optimal performance, strict alignment of the 120.65 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
