Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRAM5 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.
Yes, PRS Bearings is a leading OEM partner. We offer bulk B2B pricing for the PRAM5, along with custom laser marking, specialized packaging, and technical documentation (MTR/COC) tailored to your company's requirements.
The standard PRS Bearings PRAM5 is designed for rigid configurations. For optimal performance, strict alignment of the 38.1 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
Engineered for heavy-duty endurance, the PRS Bearings PRAM5 offers a dynamic load rating (Cr) of 1,001 and a static load rating (Cor) of 1,779. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
