Designs and variants
NKIA series bearings
• can accommodate axial loads in one direc-
tion and, therefore, locate the shaft in one
direction only
• can be mounted back-to-back (ig. 24), for
short shafts and where changes in length
due to thermal expansion are relatively
minor

NKIB series bearings

• can locate the shaft in both directions
• have axial clearance, between 0,08 and
0,25 mm
• have a two-piece inner ring to facilitate
mounting
When mounting the inner ring, it is
important that the two pieces are axially
clamped to one another
• have inner rings, which are not inter-
changeable with those from another
seemingly identical bearing (keep together
as supplied)
