finish and accuracy
Nice ball bearings
are available in several different finish and accuracy grades that may
be selected to suit the functionality of a particular application.
Nice fully ground
precision bearings are available in single row radial configurations.
Boundary dimensions and internal fit-up are held to exacting tolerances
by precision grinding of all external surfaces and both ball grooves.
These bearings are recommended for applications requiring quiet running,higher
speeds, and applied loads. Normal tolerances for series 1600, 7500,
and 7600 bearings range from 0.0005" to 0.001". See product tables for
precision and unground bearings are designed for those applications
where speeds and loads are moderate, and running accuracy and noise
requirements do not warrant a fully ground precision bearing. Single
row radial,single row angular contact,and thrust ball bearings can be
supplied in semiground or unground accuracy. Series 3000, 6900, 400,
5000, 500, and 600 bearings are available with functional tolerances
that range from 0.005" to 0.010". See product tables for exact tolerances.
