Find key technical answers regarding dimensions, specifications, and replacement options for this model.
PRS Bearings recommends storing the PR045UU in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
Every PR045UU 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.
The PR045UU utilizes high-purity bearing steel treated with PRS Bearings's advanced thermal processes. This creates a tough core that effectively absorbs shock loads while maintaining a highly wear-resistant surface on the raceways.
The PR045UU is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 6,010 dynamic load rating without introducing excessive rotational inertia.
