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.
