21318 EK

The 21318 EK is a high-performance spherical roller bearing designed to handle demanding industrial applications. It features two rows of symmetrical rollers, a common sphered outer ring raceway, and inner ring raceways inclined at an angle to the bearing axis. This robust construction makes it uniquely capable of accommodating extremely heavy radial loads and significant axial loads in both directions. Crucially, the 21318 EK is self-aligning, meaning it can tolerate misalignment and shaft deflections without experiencing a substantial increase in friction or temperature, ensuring reliable operation even in challenging operating conditions.

This specific bearing model boasts a tapered bore (designated by the "K" suffix, typically a 1:12 taper) for mounting directly onto a tapered shaft journal or, more commonly, with a withdrawal or adapter sleeve. The "E" suffix indicates an optimized internal geometry and a flangeless inner ring, maximizing the bearing's dynamic load carrying capacity and overall service life. Standard dimensions are 90 mm bore diameter, 190 mm outside diameter, and 43 mm width. The design often includes lubrication holes and a groove in the outer ring to facilitate efficient relubrication, contributing to extended wear resistance and longevity across a wide range of heavy machinery.
