HIGH PRECISION SPINDLE BALL BEARINGS GRW: highest speed and great bearing capacity Spindle ball bearings are single-row angular contact ball bearings with a contact angle of 15° or 25° that can support load on one side. In respect of their design, their running accuracy and the materials used, they are optimised for highest speed and great bearing capacity. GRW spindle ball bearings are characterised by the following properties: Manufacture in grade P4 (or ABEC7) or better Rings generally made of corrosion-resistant SV30 high-grade steel Steel or ceramic balls available for all types Machined solid retainer of fiber-reinforced phenolic resin or special materials, for example for applications involving higher temperatures 15° (C) or 25° (E) contact angle as a standard Optionally, bearings can be paired with three pre-defined preload classes (L, M, S) or individual preload Oil or grease lubrication Open and closed versions available Assembly, lubrication and packaging pursuant to cleanroom grade 10,000 Open spindle ball bearings Standard version with large balls for optimum utilization of the bearing interior and solid retainer for high bearing capacity.
