Frequently Asked Questions about PXC300 PX 4-Point Contact Ball Bearing

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

The PXC300 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 762 mm, an outer diameter of 781.05 mm, and a width of 9.525 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 9.5 mm and a balanced D/d ratio of 1.02 for high-precision housing fits.
The standard PXC300 from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 762 mm x 781.05 mm dimensions without warping.
Certainly. While the standard PXC300 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.
PRS Bearings provides the PXC300 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.
