Features :
1)Optimum design:
NSK high speed precision motorized spindle bearing 45BNR10S optimum
design achieved by computer simulation of temperature rise
resulting from ball skid.
2) Long life :
Enhanced service life measures include raising the seizure limit
under low lubrication and high speed operation conditions.
3) High accuacy
Highly accurate P2 series is available.
NSK’S experence and know-how ensure bearing specifications with a high
degree of accuracy.
4) High speed
Benefits of the light weights,high strength engineered resin cage
include heat resistance and high rigidity ,making this cage
indispensable for high-speed applications .
5) Low noise
NSK high speed precision motorized spindle bearing 45BNR10S Eliminates noise caused by compressed air of the oil-air
lubrication system .

definition
angular contact ball bearings in a tandem arrangement are used when the actual thrust force
exceeds the thrust load capacity of a single angular contact ball
bearing , Single row angular contact ball bearings in tandem arrangement must
always be adjusted against another bearing inversely arranged for
shaft guidance in the opposite direction , Single row angular contact ball bearings in spindle bearing design must not be exposed to any misalignments
.
