Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered for heavy-duty endurance, the PRS Bearings PXF120 offers a dynamic load rating (Cr) of 35,959 and a static load rating (Cor) of 64,010. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
The standard PXF120 from PRS Bearings is heat-stabilized for temperatures up to 120°C. For extreme heat applications, PRS Bearings offers custom S1 or S2 stabilization treatments to ensure the component maintains its 304.8 mm x 342.9 mm dimensions without warping.
Every PRS Bearings PXF120 is treated with premium rust-preventative oil and vacuum-sealed or wrapped in VCI paper. This guarantees that the 304.8 mm bore and 342.9 mm outer surfaces remain pristine during overseas transit.
The PRS Bearings PXF120 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the PX 4-Point Contact Ball Bearing fits snugly against shaft shoulders, preventing stress concentration at the 304.8 mm bore interface.
