12.7 mm 787.4 mm 762 mm PRD300 Frequently Asked Questions about PRD300 PR Radial Contact Ball Bearing
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRD300 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 22,922 dynamic load rating without introducing excessive rotational inertia.
Yes, PRS Bearings is a leading OEM partner. We offer bulk B2B pricing for the PRD300, along with custom laser marking, specialized packaging, and technical documentation (MTR/COC) tailored to your company's requirements.
Engineered for heavy-duty endurance, the PRS Bearings PRD300 offers a dynamic load rating (Cr) of 22,922 and a static load rating (Cor) of 92,790. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
Yes. Through optimized internal geometry and precision honing, PRS Bearings minimizes the rolling friction of the PRD300. This lowers operating temperatures and power consumption, particularly when running near its 660 RPM threshold.
