PAD045 12.7 mm 139.7 mm 114.3 mm Frequently Asked Questions about PAD045 PA Angular Contact Ball Series
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The standard PAD045 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 114.3 mm x 139.7 mm dimensions without warping.
To maximize the performance of the PAD045, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 114.3 mm bore. For the 139.7 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
The PAD045 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 8,590 dynamic load rating without introducing excessive rotational inertia.
Yes, beyond standard ISO specifications, PRS Bearings can produce the PAD045 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
