High Speed Precision NSK Motorized Spindle Bearing 45BNR10S Angular Contact ball bearing 45*75*16mm

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 .

NSK NSK motorized spindle bearing 45BNR10S 45BNR10STYNDBBELP4 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 .
