The Daedal GTN90 precision gearheads are obsolete and no longer available. For replacements, the Stealth Gen II PS90 servo class gearbox is a very close replacement.
GTN Ratios were 3, 4, 5, 8, 10, 12, 15, 16, 20, 25, 32, 40, 64, 100.
PS standard ratios are 3, 4, 5, 7, 10, 15, 20, 25, 30, 40, 50, 70, 100.
PS with 8:1, 12:1, 16:1, 32:1 and 64:1 ratios are available as custom.
Dimensional comparison presumes standard GTN S7 output shaft option.
Custom PS90 gearboxes with lower backlash for high accuracy applications are available.
Custom PS90 gearboxes with shorter output shaft length for dropin replacement are available.
Note that the Stealth gearheads and mounting kits are purchased as separate items:
1. PS90-010-L2.....Inline PS90 Stealth Gen II gearhead, 10:1 ratio low backlash
2. MU90-005.........Mounting kit
The MU90-005 is the mounting kit for the BE34 motor. 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 parkermotion.com
The above is summarized based on catalog specifications. However, application requirements may be different; the PX90 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.
