Design of bearing arrangements
Design of bearing
arrangements
Free space on both sides of the bearing
To prevent interference between rotating and
stationary components, the abutment diameter
on the shaft should be < d 2 and in the
housing > D 1 († fig. 13). Values for d 2 and D 1
are listed in the product tables.
The necessary width of the free space C a
depends on:
• the actual misalignment
• the possible protrusion of the cage from the
side face of the bearing for some bearing
sizes
• lubrication requirements
That requisite free space should be at least 20
times the minimum value of the radial internal
clearance in the unmounted bearing
(† table 4, page 892 or table 5, page 893).
For additional information, contact the SKF
application engineering service.
