Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PRS Bearings PXA075 is designed for rigid configurations. For optimal performance, strict alignment of the 190.5 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXA075. This lowers operating temperatures and power consumption, particularly when running near its 1,550 RPM threshold.
Every PXA075 batch undergoes 100% automated vibration and noise testing at the PRS Bearings factory. We guarantee compliance with Z1/V1 standards, with premium Z3/V3 options available for high-end electric motors.
As a dedicated bearing manufacturer, PRS Bearings maintains strategic inventory of the PXA075 for prompt dispatch. For large OEM forecast orders, our lean production lines guarantee highly competitive lead times.
