Unlike single direction thrust ball bearing types,
double direction thrust ball bearings are suitable to guide the shaft in
both directions. (see Abb. d, a and f)
These bearings consist of two housing washers, two ball and cage thrust assemblies with one common shaft washer located centrally in between.
Double direction thrust ball bearings are also available in both designs, with flat housing washers (series 522, 523 and 524, see d below) and with sphered housing washers (series 542, 543 and 544, see a below).
For compensation of possible aligning errors the double direction thrust ball bearings may be used in conjunction with Seating Washers (series U2, U3 and U4, see f below).
All thrust ball bearing types with flat housing washers do not allow any misalignment.
The contacting surfaces of both shaft and housing seats must be parallel.
Misalignments can only be accommodated by using Thrust Ball bearings with sphered housing washers.
NKE thrust ball bearings are normally fitted with pressed steel cages as standard.
For larger thrust ball bearings solid brass cages, (suffix M), or solid steel cages, (suffix F), are fitted as standard.
