Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, PRS Bearings is a leading OEM partner. We offer bulk B2B pricing for the PXG055, along with custom laser marking, specialized packaging, and technical documentation (MTR/COC) tailored to your company's requirements.
The standard PRS Bearings PXG055 is designed for rigid configurations. For optimal performance, strict alignment of the 139.7 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Under optimal lubrication conditions, the PRS Bearings PXG055 can reach a limiting speed of 1,850 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
The PXG055 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 39,941 dynamic load rating without introducing excessive rotational inertia.
