Metric roller bearing units SYNT and FYNT series (SKF ConCentra)
Standard bearing unit design Fig. 1
SYNT series
SKF ConCentra roller bearing units consist of a
non-split housing, an SKF spherical roller
bearing on an SKF ConCentra stepped sleeve,
seals and grease. Bearing units for metric
shafts are available in two series, depending
on the housing design. Bearing units in the
SYNT series have a non-split plummer (pillow)
block housing with two holes cast into the base
for attachment bolts († fig. 1). Bearing units
in the FYNT series have a flanged housing and
are produced in two designs († fig. 2):
• For shaft diameters from 35 to 60 mm, the
housings have a triangular flange and three
drilled holes for attachment bolts.
• For shaft diameters from 65 to 100 mm, the
housings have a square flange and four Fig. 2
drilled holes for attachment bolts. FYNT series
The bearings used in SKF ConCentra roller
bearing units are upgraded SKF Explorer
spherical roller bearings in the 222 series. The
stepped sleeve has inclined serrations that
match the profile of the bearing bore. The
bearing unit also contains a mounting collar,
washer, back-up collar and wave spring. The
mounting collar is equipped with grub (set)
screws that are pos itioned at an angle (not
horizontal) to facilitate mounting and dis-
mounting († fig. 3).
