Bearings

 

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.

AA GROUP is a professional distribution of imported bearings, including SKF bearings, and other famous brands, which we operate the products are all available directly from HongKong, Singapore, Malaysia, Japan, Germany and other places, at reasonable prices to ensure quality.after years of effort and hard work, the company’s products are widely used in: aerospace, wind energy, rail transportation, motorcycle automobile, mining and metallurgy, engineering machinery, machine tools, motors, etc.,
