15C Bearings with Solid Oil
Bearing data
Dimension standards, tolerances,
internal clearance
Dimensions, tolerances and internal clearance
of bearings or units with Solid Oil are the same
as for the corresponding standard products.
Loads
Minimum load
The weight of the components supported by
the bearing, together with external forces,
generally exceed the requisite minimum load.
If this is not the case, the bearing must be subjected
to an additional radial load.
The minimum load for bearings with Solid
Oil should be slightly higher than the minimum
load for standard bearings. Recommendations
for calculating the requisite minimum loads for
the different standard bearing types are provided
in the relevant product chapter.
Temperature limits
The temperature limits for bearings with Solid
Oil are valid for both open and capped bearings.
The relevant limits are:
• minimum († table 1, page 1187)
• maximum 85 °C (185 °F) for continuous
operating conditions
• maximum 95 °C (205 °F) for intermittent
operating conditions
If bearings with Solid Oil are to be hot mounted,
SKF does not recommend heating the bearing
above 80 °C (175 °F). However, if higher temperatures
are necessary, make sure that the
temperature does not exceed the permissible
temperature of either the seal or Solid Oil,
whichever is lowest. If an induction heater is
used, mounting temperatures of up to 120 °C
(250 °F) are permissible.
Load carrying capacity
The basic dynamic and static load ratings for
bearings with Solid Oil are the same as for
same-sized standard bearings.
