Radial Internal clearance
IntroductionSelection Guide Engineering DataBrochure
All Nice single
row deep groove ball bearings are designed and produced with radial
internal clearance to provide for optimum performance. Nice ball bearings
are supplied with "normal" radial clearance as standard, but can be
ordered with radial clearance tighter than normal or looser than normal
as a special item. The values listed in the table below apply to bearings
before mounting and under no load and are supplied as a design guide.
Consult Nice engineering when ordering other than normal radial clearance.
