These three mated, sealed, ultra-precision angular contact ball bearings are available in a variety of designs, variants, and configurations, allowing them to be used in virtually any machine tool application and other applications that require precision bearings. Pre-configured configurations include: "Tandem", "Back-to-Back Plus Tandem", "Face to Face Plus Tandem". Bearing sets arranged in a back-to-back plus series or face-to-face plus series arrangement have different preload classes and when installed correctly will generate preload within a pre-set range without the use of spacers or similar equipment. Three-bearing mated bearing sets require two mating bearings in series to be mounted in close proximity to each other on a single bearing to obtain the required preload. The inner and outer diameter tolerances of mated bearings do not exceed one-third of the permissible diameter tolerances, resulting in a more uniform load distribution than a single universal mating bearing. load
