Ang single row spacer ay nag-assemble ng 2TS-DM(directing mounting)HM903249 Bearing

Any two matching single-row bearings (type TS)  can be supplied as a double-row, pre-set, ready-to-fit assembly by the addition of spacers, machined to pre-determined dimensions and tolerances.  

There are two basic mounting arrangements for single-row spacer assemblies:

Type 2TS-IM (indirect mounting) 

These consist of two single-row bearings with an inner-ring and outer-ring spacer. In some applications, the outer-ring spacer is replaced by a shoulder in the bearing housing.

Type 2TS-DM (direct mounting) 

These consist of two single-row bearings, with cone (inner-ring) backfaces abutting and an  outer-ring spacer. They are generally used at fifixed (locating) positions on rotating shaft  applications.
