Replacement for GTR70

The Daedal GTR70 precision gearheads are obsolete and no longer available. For replacements, the Stealth Gen II RS60 servo class gearbox is a close replacement.

Performance comparison:

Dimensional comparison:

GTR Ratios were 4, 5, 8, 10, 16, 20, 25, 32, 40, 64, 100.
RS standard ratios are 5, 10, 15, 20, 25, 30, 40, 50, 100.
RS with 8:1 and 64:1 ratios are available as custom. Other ratios can be investigated as custom.

Dimensional comparison presumes standard GTR S7 output shaft option.

*Custom RS60 available with lower backlash for high accuracy applications.

Note that the Stealth gearheads and mounting kits are purchased as separate items:
1. RS60-010-L2.....Inline RS60 Stealth Gen II gearhead, 10:1 ratio low backlash
2. MU60-059.........Mounting kit

The MU60-059 is the mounting kit for the SM23 motors and MU60-033 is the mounting kit for the BE23 motors. When ordered together on the same order as consecutive line items, the mounting kit will be attached to the gearhead and bushing inserted inside the pinion. Hardware to fit the motor to the adapter is also provided. For all other mounting kit part numbers, see the mounting kit search tool on

The above is summarized based on catalog specifications. However, application requirements may be different; the RX60 Stealth GenII gearhead could also be considered for lower accuracy applications. Please contact your local Parker ATC to review machine requirements or for gearhead sizing assistance.

For torque and sideload/axial load capacity, see catalog pages.
