SKF 2311 tilting ball bearing

Product detailed description

SKF 2311 is a self-aligning ball bearing designed for applications requiring the ability to compensate for misalignment of the shaft relative to the bearing seat. The bearing has an outer diameter of 120 mm, an inner diameter of 55 mm and a width of 43 mm. It is made of high-quality steel, which is the standard for rolling bearings, which guarantees its long life and reliability.

This type of bearing is characterized by its self-aligning ability, which is made possible by its design with two rows of balls and a spherical outer surface of the outer ring. Thanks to this design, the bearing can compensate for misalignment up to several degrees, which is ideal for applications where precise alignment is difficult to ensure.

The SKF 2311 bearing is equipped with a pressed steel cage that ensures optimal ball guidance and minimizes friction. The bearing is sealless, which means it is suitable for applications where protection against dust or moisture is not required, or where an external seal is provided.

The operating temperature range of the bearing is from -30 °C to +150 °C, which allows it to be used in a wide range of applications and environments. The bearing has normal radial clearance, which is suitable for most standard applications where special clearance conditions are not required.

The running accuracy is in class P0/PN, which corresponds to ABEC 1 accuracy class, and is sufficient for common industrial applications. The total weight of the bearing is 2.1 kg, which is important to consider when designing and installing within mechanical systems. SKF 2311 is an ideal choice for applications where high reliability and the ability to compensate for misalignment are required.
