1208K Self Aligning Bearing | AXIS 1208K Bearing - 40x80x18

This tapered bore 1208K self-aligning bearing is a high-performance 40x80x18 ball bearing manufactured to an elevated standard by AXIS. What sets this 1208K 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 1208K bearing features raceways that are precision honed to a superb finish.

Self-aligning 1208K 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 1208K 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.
