Spacer Couplings – SM Series
The TransDrive SM Series spacers, when paired with cone ring or tyre couplings, offer a practical and efficient solution for maintenance tasks. These spacers create additional room between connected shafts, allowing either the driving or driven machine to be moved or serviced without disturbing the alignment or mounting of the other unit. This design significantly reduces downtime and simplifies equipment servicing in tight or critical installations.
To suit a range of applications, TransDrive offers standard Distance Between Shaft Ends (DBSE) lengths of 100mm, 140mm, and 180mm. Custom lengths may also be available upon request to meet specific operational requirements.
Selection Procedure
- Use the selection procedure to select a suitable Cone Ring/ Tyre Coupling.
- Select suitable Spacer taking into consideration the required shaft spacing.

Ordering Instructions
- SM Spacers are specified by the size end DBSE (eg. A SM35 spacer with a 140mm DBSE length is specified as a SM35-140)
- SM Spacers require a Taper Fit bush which must be ordered as a separate item (specifying bush size end the required bore).
- To order a complete Spacer coupling list the individual components of the coupling and spacer including required Taper Fit bushes.
