NU2307E Cylindrical roller bearings provide the highest possible radial load capacity compared to other roller bearing types. Four primary styles are available to meet a variety of application requirements.
The rollers of Cylindrical roller bearings are a key component. Their geometry, the so-called logarithmic profile, provides an optimum stress distribution in the contact zones in the bearing. Their surface finish maximizes lubricant film formation and optimizes rolling motion of the rollers. The benefits derived from this compared with traditional designs include enhanced operational reliability and a greater insensitivity to misalignment.
