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.
The outer ring has one shoulder only. The increased height of the snap feature prevents bearing collapse.
Solid retainer guided on outer ring with low cross-section, particularly well suited for oil injection lubrication.
