Frequently Asked Questions about PXD180 PX 4-Point Contact Ball Bearing

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

Every PRS Bearings PXD180 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 457.2 mm bore and 482.6 mm outer surfaces remain pristine during overseas transit.
To maximize the performance of the PXD180, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 457.2 mm bore. For the 482.6 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
Thanks to its robust 23,246 dynamic load capacity, the PRS Bearings PXD180 is highly sought after in mining, metallurgy, agricultural machinery, and heavy industrial gearboxes where operational reliability is paramount.
Certainly. While the standard PXD180 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.
