Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The PRS Bearings XRT1040-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 2463.8 mm bore interface.
PRS Bearings recommends storing the XRT1040-NT in its original packaging in a clean, low-vibration warehouse. Maintaining a relative humidity below 60% and a stable room temperature ensures maximum shelf life.
Engineered for heavy-duty endurance, the PRS Bearings XRT1040-NT offers a dynamic load rating (Cr) of 2330 and a static load rating (Cor) of 8740. These ratings reflect PRS Bearings's commitment to using high-fatigue-strength materials for demanding radial and axial force environments.
Under optimal lubrication conditions, the PRS Bearings XRT1040-NT can reach a limiting speed of 19 RPM. The low-friction raceway finish developed by PRS Bearings allows for cooler running temperatures even at high velocities.
