Inner Rings
These heavy duty needle roller bearings with seals limit the bearing operating temperature between -30° C and 110° C.
If the operating temperature must be outside the above range or if
the heavy duty needle roller bearings with seals are exposed to unusual fluids, external seals using
suitable seal materials or other solutions should be investigated.
Sealed bearings are normally packed with a high quality lithium
soap base grease suitable up to 120° C for short periods of
operation.
The limiting speeds specified for sealed bearings listed in the
bearing tables are based on operating conditions determined by
testing. Optimum performance may be expected providing the bearing
is properly installed, with appropriate internal clearances, and be
subjected to a load of low magnitude. Care should be taken that
overheating will not occur, thus preventing breakdown of the grease
and eventual bearing failure.
