SKF - Rolling Bearings

Designs and variants
Cages
Depending on their design, series and size,
SKF needle roller bearings are fitted with one
of the cages shown in table 3 († page 694).
The standard cage is not identified in the
bearing designation.
The lubricants generally used for rolling
bearings do not have a detrimental effect on
cage properties. However, some synthetic oils
and greases with a synthetic oil base and
lubricants containing a high proportion of EP
additives, when used at high temperatures, can
have a detrimental effect on polyamide cages.
For additional information about the suitability
of cages, refer to Cages († page 37) and
Cage materials († page 152).
Double row needle roller bearings
Double row needle roller and cage assemblies
have a double row cage in the same design as
a single row cage († fig. 1, page 675).
Other double row needle roller bearings
are equipped with two cage assemblies
(† fig. 15, page 681 and fig. 16, page 682).
