2TS-DM assemblies are comprised of two single-row bearings with abutting back facing inner rings and an outer ring spacer with lubricating holes is typical. These are generally used at fixed positions on rotating shaft applications.
Design Attributes:Two single row bearings, with or without a spacer
When spacers are used, bearing is furnished as a preset, matched assembly
Spacers available with or without lubricant grooves and holes
