For bearing arrangements, which have to operate at extreme temperatures in the range –150 to +350 °C, or which have to withstand very large temperature differences, e.g. in kiln trucks, furnaces or the conveyor systems of lacquering equipment, normal rolling bearings are unsuitable. SKF has therefore developed high-temperature:

– Deep groove ball bearings (fig. 1).

– Y-bearings (fig. 2).

– Y-bearing plummer block units (fig. 3).

– Y-bearing flanged units.


To meet the widely differing engineering demands for:

– Reduced machine operating costs

– Extended maintenance-free service life

– High operational reliability


In this wide temperature range, even in a severe environment. The bearings and units for high temperature belonging to the SKF standard assortment are described in the following and listed in the relevant product tables. To special order SKF can produce bearings for extreme low or high temperatures, which are engineered to meet specific needs.
