Max Type M6308 Ball Bearing | M6308 - 40x90x23

This M6308 ball bearing is a high-precision premium quality MAX Type deep groove 40x90x23 ball bearing made to ABEC 3 precision standards from AXIS. What sets this M6308 bearing apart from others is the way that MAX Type bearings are constructed, the ABEC 3 precision standard that this bearing is made to, the grade 10-balls used, and the superb electric motor quality rating (EMQ). Max type bearings allow for additional balls inside a bearing through the use of a filling notch on the bearing's inner and outer ring. This bearing style offers additional radial load capacity over a standard Conrad style ball-bearing due to the increased ball count. However, due to this filling notch's presence, the bearing's axial (thrust) capacity is diminished. These bearings can be used in applications where heavy radial loads are present or in applications with radial and axial loads, given the axial load is minimal. Their use is not recommended in applications where only axial loads exist. 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 M6308 bearing features raceways that are precision honed to a superb finish.

More specifically, M6308 ball bearings are found in a wide range of industrial and automation applications. They are designed to reduce rotational friction and support loads. The load is spread evenly across the grade 10 balls, and as the inner bearing race rotates, so do the balls.
