Description Technical Specs
 
This tapered bore 2311K-2RS self-aligning bearing is a high-performance 55x120x43 ball bearing manufactured to an elevated standard by AXIS, it has a rubber seal on both sides designated by (2RS). What sets this 2311K-2RS bearing apart from others is the ABEC 3 precision standard that this bearing is made to, the grade 10-balls used, and the superb electric motor quality rating (EMQ). ABEC 3 means that the bearing has a micron deviation from a nominal of 20.000mm of -8 micrometers. The standard ABEC 1 precision standard that almost all ball bearings are made to today has a deviation of -10 micrometers. In simple terms, the more precision a bearing is, the better it will perform in any given application. The grade 10 balls within this bearing are typically only found within ABEC 5 or higher bearings because of their more true roundness and precision. The balls within a bearing share the load capacity, which also increases the working life versus the standard grade 25 balls used in other brands. The electric motor quality rating means that the bearing must operate at an extremely low noise level with minimal to no vibration. To achieve this, the 2311K-2RS bearing features raceways that are precision honed to a superb finish.

Self-aligning 2311K-2RS bearings are designed with two rows of balls; the inner raceway consists of two grooves to support each row of balls, while the outer raceway has only one groove for both sets of balls. This design creates a self-centering effect with flexibility between the two rings; the result is a 2311K-2RS bearing insensitive to angular misalignment. Making this bearing ideal in applications that are prone to shaft deflection and misalignments. The K at the end of the part number designates that this is a tapered bore self-aligning bearing; the tapered bore is often used to facilitate mounting and dismounting, or in some cases, is essential to the application. The bearing can either be mounted directly onto a tapered shaft or with the use of an externally tapered sleeve.
