Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To maximize the performance of the XRT740-NT, PRS Bearings technical engineers suggest a shaft fit of k5/m5 for its 1879.6 mm bore. For the 2197.1 mm outer diameter, an H7 or J7 housing tolerance is ideal to accommodate thermal expansion while maintaining PRS Bearings's signature operational stability.
Yes, while the standard PRS Bearings XRT740-NT meets ISO P0 (ABEC-1) levels, PRS Bearings also manufactures high-precision variants in P6 (ABEC-3) and P5 (ABEC-5) for applications requiring minimal runout and extreme rotational accuracy.
The PRS Bearings XRT740-NT features precision-machined corner chamfers designed to facilitate easier mounting. These ISO-standard chamfers ensure that the XRT Series Crossed Tapered Roller Bearings fits snugly against shaft shoulders, preventing stress concentration at the 1879.6 mm bore interface.
Yes. As part of our B2B commitment, if a XRT740-NT experiences unexpected issues in the field, PRS Bearings engineers can perform detailed metallurgical and wear analysis to identify root causes and optimize your future setups.
