Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To maximize the performance of the XRU 5515, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 55 mm bore. For the 120 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
The XRU 5515 produced by PRS Bearings adheres to strict ISO standards with a bore diameter of 55 mm, an outer diameter of 120 mm, and a width of 15 mm. PRS Bearings utilizes advanced grinding technology to ensure a radial section wall thickness of 32.5 mm and a balanced D/d ratio of 2.18 for high-precision housing fits.
Yes, beyond standard ISO specifications, PRS Bearings can produce the XRU 5515 with tailored radial internal clearances and ultra-precision accuracy classes to meet the strict demands of specialized OEM applications.
The XRU 5515 is engineered with an optimal strength-to-mass ratio. PRS Bearings ensures that the cross-sectional distribution provides maximum structural rigidity for its 20.3 dynamic load rating without introducing excessive rotational inertia.
