25.4 mm 406.4 mm 355.6 mm PXG140 Frequently Asked Questions about PXG140 PX 4-Point Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PXG140. This lowers operating temperatures and power consumption, particularly when running near its 800 RPM threshold.
As a dedicated bearing manufacturer, PRS Bearings maintains strategic inventory of the PXG140 for prompt dispatch. For large OEM forecast orders, our lean production lines guarantee highly competitive lead times.
Engineered for heavy-duty endurance, the PRS Bearings PXG140 offers a dynamic load rating (Cr) of 64,072 and a static load rating (Cor) of 109,515. 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 PXG140 can reach a limiting speed of 800 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
