The SKF Cold Tight systems offer considerable benefits. The SKF CT reduces downtime by several days each time a steam turbine is opened and closed. Long cool-down periods are not needed. The system also helps in planning the outage more efficiently.

SKF needle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers. The very small diameter deviation of the rollers within one assembly enables these bearings to accommodate heavy axial loads and shock loads.

SKF thrust ball bearings are manufactured as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.
Single direction thrust ball bearings
SKF single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage assembly.

Double direction thrust ball bearings
SKF double direction thrust ball bearings consist of one shaft washer, two housing washers and two ball and cage assemblies.
