he Thin Section Radial Contact (or Deep Groove) Ball Bearings
refers to the single row deep groove bearing that consists of an
inner ring and an outer ring with super deep grooves. The depth of
the raceway groove equals to *5% of the diameter of the steel ball.
The performance is the best when the radial clearance between the
steel balls and the raceway is smallest. There are three reasons
why the standard bearings are provided with certain clearance: (1)
the interference fits between bearings and mounting area; (2) the
different thermal expansions or contractions of the different steel
raceways; (3) the change of the clearance due to the misalignment
between the shafts and the housing. Therefore, the center of the
raceway radius is on the centerline of the steel
balls.
Thin Section Radial Contact Ball Bearings are designed to save
space, decrease the overall weight, dramatically reduce friction,
and provide excellent running accuracy. The special features of the
Thin Section Bearings enable customers to downsize their design and
cut manufacturing costs without sacrificing bearing performance or
service life.
