SKF 22311 EK/C3 cylindrical roller bearing

Product detailed description

SKF 22311 EK/C3 is a spherical roller bearing designed for applications requiring high load capacity and the ability to compensate for misalignment. The bearing has an inner diameter of 55 mm, an outer diameter of 120 mm and a width of 43 mm. It is made of high-quality steel, standardly used for rolling bearings, which ensures its durability and long service life.

The bearing is equipped with a tapered bore with a taper of 1:12, which allows it to be easily mounted and dismounted on tapered shafts or using adapter sleeves. The internal radial clearance is of category C3, which means that it is slightly increased, making it suitable for applications with higher operating temperatures or where greater clearance is required to compensate for thermal expansion.

The outer ring of the bearing contains a lubrication groove and lubrication holes, which allows effective lubrication and thus extends the service life of the bearing. The bearing is sealless, which means it is designed for applications where external lubrication and protection against dirt are provided.

The steel cage of the bearing is pressed, which ensures strength and stability at high speeds and loads. The bearing is able to operate in a temperature range from -30 °C to +200 °C, which makes it suitable for various industrial applications.

The running accuracy of the bearing is defined by the dimensional accuracy PN and the operating accuracy P5, which guarantees reliable and precise operation in demanding conditions. The total weight of the bearing is 2.4 kg, which is optimal for its design features and use in various mechanical assemblies.
