Deep Groove Ball Bearings 12x28x8mm 6001ZZ China Manufacturer is a high-precision premium quality deep groove shielded 12x28x8 ball bearing made to ABEC 3 precision standards. What sets this 6001ZZ 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 itself 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, so this 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 6001ZZ bearing features raceways that are precision honed to a superb finish.
More specifically, 6001ZZ deep groove 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 25 balls and as the inner bearing race rotates so do the balls. The metal shields located on each side of the ball bearing keep the bearing lubricant in while keeping unwanted contents out.
