As far as I can see, these two sizes appear to use ball-cage assemblies with the identical dimensions, it is just that the 22mm types have wider washers.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">BTW, you can also get F8-16M ball thrust bearings with washers that are flat with no groove, and lower-profile roller thrust bearing with similarly flat washers, neither of which provide any lateral location.</span></p><p><br/></p>
