Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PXC120 is designed for rigid configurations. For optimal performance, strict alignment of the 304.8 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
PRS Bearings provides a comprehensive B2B warranty for the PXC120 against manufacturing defects. Furthermore, our engineering team offers ongoing technical support to ensure the PX 4-Point Contact Ball Bearing operates optimally within your specific machinery.
The PXC120 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 11,663 dynamic load rating without introducing excessive rotational inertia.
PRS Bearings provides the PXC120 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.
