12.7 mm 330.2 mm 304.8 mm PXD120 Frequently Asked Questions about PXD120 PX 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The precise manufacturing of the PRS Bearings PXD120 results in stable, predictable vibration baselines. This makes it highly compatible with modern IoT condition monitoring sensors for early fault detection.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXD120. This lowers operating temperatures and power consumption, particularly when running near its 960 RPM threshold.
Every PRS Bearings PXD120 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 304.8 mm bore and 330.2 mm outer surfaces remain pristine during overseas transit.
The standard PRS Bearings PXD120 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.
