22317 EK

The 22317 EK Spherical Roller Bearing is engineered for heavy-duty applications, delivering exceptional performance where reliable load handling and self-alignment are critical. Featuring a tapered bore (1:12), this bearing is designed for mounting with adapter sleeves, simplifying installation and removal on plain or stepped shafts. Its construction incorporates an optimized internal geometry and high-capacity rollers, allowing it to manage extremely high radial and axial loads simultaneously. The bearing is also equipped with relubrication features (groove and holes in the outer ring), ensuring extended service life and consistent operation in challenging industrial environments. With precise dimensions of 85mm inner diameter, 180mm outer diameter, and 60mm width, the 22317 EK is a robust component built for durability.

This double-row spherical roller bearing inherently accommodates significant shaft deflection and misalignment without compromising its load capacity or generating excessive friction-a crucial advantage in demanding machinery. The "EK" designation signifies an enhanced internal design (often high-capacity) and a tapered bore, making it a highly versatile choice for industrial maintenance, repair, and overhaul (MRO). Typical applications for the 22317 EK include large-scale equipment such as gearboxes, heavy-duty pumps, crushers, vibrating screens, and machinery used in mining, construction, and papermaking. When selecting the 22317 EK, buyers benefit from a product that combines a large static load rating (approx. 620 kN) and a high limiting speed (up to 3800 r/min), ensuring operational stability and efficiency under severe operating conditions.
