Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, while the standard PRS Bearings PX110UU meets ISO P0 (ABEC-1) levels, PRS Bearings also manufactures high-precision variants in P6 (ABEC-3) and P5 (ABEC-5) for applications requiring minimal runout and extreme rotational accuracy.
The PRS Bearings PX110UU features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PX Sealed 4-Point Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 279.4 mm bore interface.
Every PX110UU 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.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PX110UU. This lowers operating temperatures and power consumption, particularly when running near its 180 RPM threshold.
