Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Certainly. While the standard PXA025 is pre-filled with high-grade industrial lubricant, PRS Bearings can provide custom fills, including food-grade (NSF H1), high-temperature, or extreme-pressure greases tailored to your operational needs.
Every PRS Bearings PXA025 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 63.5 mm bore and 76.2 mm outer surfaces remain pristine during overseas transit.
The PXA025 utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
The standard PRS Bearings PXA025 is designed for rigid configurations. For optimal performance, strict alignment of the 63.5 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
