Running accuracy, axial load capacity and rotational speed – when it comes to these features, spindle ball bearings yield excellent results all around. GRW develops customized solutions to meet the specific needs in sectors such as aviation and space or medical technology. Among these options our single-row, angular-contact ball bearings stand out to first-rate precision and long-term durability. Commonly known as spindle bearings, they consist of solid inner and outer rings as well as ball sets with window cages. Characteristics of GRW Spindle Ball Bearings -accuracy class of ABEC 7 (DIN P4) and higher -contact angle of 15° (C) or 25° (E) -corrosion-resistant, high-performance steel -balls made from ceramics or steel -solid cages made from phenolic resin -oil or grease lubrication -suitable for bearing combinations with three defined preload classes -(S, M, L) or individual preload force How to Install and Handle Angular-Contact Ball Bearings -Keep your workspace tidy and clean. -Avoid damage by reducing movement during transport. -Leave spindle ball bearings in airtight packaging until you begin with their installation. -Apply axial load only along the marked lines on the outer ring. -Avoid transmitting assembly forces through the balls. -Assemble pair bearings of type DB, DF, and DT only with the intended components in the right order. (Universally matched bearings require no particular order.) -Let spindle ball bearings run in at high rotational speed before putting them into operation.
