Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Thanks to its robust 693 dynamic load capacity, the PRS Bearings XRT270-N is highly sought after in mining, metallurgy, agricultural machinery, and heavy industrial gearboxes where operational reliability is paramount.
The XRT270-N is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 693 dynamic load rating without introducing excessive rotational inertia.
PRS Bearings provides the XRT270-N 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.
Certainly. While the standard XRT270-N 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.
