Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings PB25025 features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the Metric PB Series Bearings fits snugly against shaft shoulders, preventing stress concentration at the 310 mm bore interface.
Yes, beyond standard ISO specifications, PRS Bearings can produce the PB25025 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
The standard PB25025 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 310 mm x 25 mm dimensions without warping.
The standard PRS Bearings PB25025 is designed for rigid configurations. For optimal performance, strict alignment of the 310 mm bore is critical, though PRS Bearings engineers can provide self-aligning bearing alternatives if your equipment is prone to deflection.
