The BTW 200 CM/SP Super-Precision Bearing is a highly specialized, double-direction axial angular contact ball bearing, meticulously engineered to provide exceptional rigidity and precise axial guidance for demanding linear motion applications. Part of a series from leading manufacturers like FAG (Schaeffler), this bearing is specifically designed to manage very high axial loads in both directions with outstanding accuracy.
The "CM" suffix typically indicates a pressed steel cage, offering durability and stable performance even under dynamic conditions. Crucially, the "SP" suffix denotes its super-precision class, meaning it is manufactured to exceptionally tight tolerances (often P4 or P2 equivalent). This ensures minimal runout, very low friction, and minimal heat generation, which are vital for maintaining accuracy at high operating speeds. These bearings are commonly supplied with a specified preload, eliminating axial play and maximizing system stiffness upon installation. Primarily utilized in machine tool screw drives, high-precision linear guidance systems, and other advanced manufacturing equipment, the BTW 200 CM/SP delivers unparalleled accuracy and reliability, directly contributing to superior machining quality and enhanced productivity.
