Along with the standard 2TS types, there are two  specialty double-row assemblies available:

Type 2S - Two single-row assembly

Supplied complete with inner-ring and outerring spacers to give a pre-determined bearing  setting when assembled. The setting range can  be specifified to suit the application. Type 2S has an inner-ring spacer and a snap-ring, which also serves as the cup spacer, to give axial location in a through-bored housing. 

Type SR - Set-Right assemblyType SR is made to a standard setting range, based on VAFEM’s Set-Right automated  setting technique, suitable for most industrial applications. It is equipped with two spacers and an optional snap-ring that may be used  for axial location.
