Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Certainly. While the standard PXB110 is pre-filled with high-grade industrial lubricant, PRS Bearings can provide custom fills, including food-grade (NSF H1), high-temperature, or extreme-pressure greases tailored to your operational needs.
Engineered for heavy-duty endurance, the PRS Bearings PXB110 offers a dynamic load rating (Cr) of 8,652 and a static load rating (Cor) of 20,417. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
Under optimal lubrication conditions, the PRS Bearings PXB110 can reach a limiting speed of 1,060 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
The PXB110 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 8,652 dynamic load rating without introducing excessive rotational inertia.
