SKF SPHERICAL ROLLER BEARING 22219 EK

Self-aligning roller bearings play a key role in the proper operation of equipment subjected to high mechanical loads. Their robust design ensures reliable and continuous performance, even under unstable or demanding operating conditions.

This spherical roller bearing features a 1:12 tapered bore. Designed to withstand high radial and axial loads, it has self-aligning capabilities, which compensate for misalignment or shaft deflection. Thanks to its double row of rollers and open design, it offers robustness, durability, and reliability, even under intense mechanical stress.

Features:
This bearing is distinguished by its double row of symmetrical rollers, which ensures even load distribution and improved operational stability. Its 1:12 tapered bore allows for precise mounting on a shaft or via a sleeve, ensuring optimal adjustment of the internal clearance. It features two windowed cages made of deep-drawn sheet steel and a flangeless inner ring. Its floating guide ring ensures effective centering. The E design, with its stamped steel window cages and a shoulderless inner ring, ensures high durability and reliable operation at high speeds. It offers a good balance between mechanical strength, load distribution, and heat reduction, while allowing for smooth rotation in heavy-duty applications. The presence of an annular groove and three holes on the outer ring facilitates regular relubrication. This bearing is ideal for dynamic operating conditions.

Maintenance:
To ensure continuous performance, regular visual inspections help detect premature wear, and regular lubrication is essential. This bearing can operate at temperatures up to 200 °C, provided a suitable high-temperature lubricant is used. The annular groove and three lubrication holes allow for even lubricant distribution. In the event of contamination, it is recommended to thoroughly clean the housings and surrounding parts before relubrication.

Sealing:
This bearing is designed without integrated seals. This open configuration facilitates maintenance and visual inspection but makes it more susceptible to contaminants. Exposure to dust, moisture, or other impurities requires increased vigilance. To compensate for this open design, the bearing incorporates lubrication features that help flush out unwanted particles and extend the bearing’s service life.
