Remarks Two bearings are
usually mounted in
opposition.
Contact angles of 15o, 25o
30o, and 40o. Two bearings are
usually mounted in opposition.
Clearance adjustment is
necessary.
Combination of DF and
DT pairs is possible, but
use on free-end is not
possible.
Contact angle of 35o
Including N type
Including NNU type
Including NF type
