Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings recommends storing the PXB025 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. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXB025. This lowers operating temperatures and power consumption, particularly when running near its 4,270 RPM threshold.
Engineered for heavy-duty endurance, the PRS Bearings PXB025 offers a dynamic load rating (Cr) of 3,772 and a static load rating (Cor) of 5,071. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
Every PRS Bearings PXB025 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 63.5 mm bore and 79.375 mm outer surfaces remain pristine during overseas transit.
