Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Depending on your thermal and fit requirements, PRS Bearings supplies the PXB090 in C0 (Normal), C2 (Tight), or C3 (Loose) internal radial clearances. Proper clearance selection by PRS Bearings specialists helps prevent premature bearing seizure.
The PXB090 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 228.6 mm, an outer diameter of 244.475 mm, and a width of 7.938 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 7.9 mm and a balanced D/d ratio of 1.07 for high-precision housing fits.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXB090. This lowers operating temperatures and power consumption, particularly when running near its 1,290 RPM threshold.
The standard PRS Bearings PXB090 is designed for rigid configurations. For optimal performance, strict alignment of the 228.6 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
