Can this pan-and-tilt kit be used to move a 15lb. object?
You’ll need to provide more information about the application. It’s intended for rotational motion, so not sure what you mean by “move”.

at least one of tilt or pan would carry the entire weight of the object…
do you know the answer?
You would need a gearbox pan and/or tilt setup:

Ex: robotshop.com/en/super-duty- … RB-Sct-179
The tilt aspect is more sensitive since the torque depends on how far you tilt the load and how far away it is from the axis of rotation.
Assuming I do not want to use gearboxes, where can I find load spec for these motors?
Servos are not rated in vertical load but rather in torque.
When choosing a pan/tilt or servos in general, you would need to understand that torque is:
en.wikipedia.org/wiki/Torque
Can you tell us a bit more about your application?
Hi,
Ok, so what is the torque spec for this motor?
Where can I see related spec for this feature/capability?
As for my application, if you don’t mind I would like to not get into details.
I thank you for your help nevertheless.

RB-Lyn-74 includes two Hitec HS-422 servos, though we do include a hardware only version so you can add your own Hitec standard servos.
The 422 can provide up to 4.1Kg-cm of torque.
If you opt for the hardware only version, you can add a Hitec 645MG which delivers up to 9.6Kg-cm

Hi,
9.6Kg-cm is equivalent to 21.12lb-cm.
If my object weight is 15lb, the radius is 21.1/15~1.4cm.
So my ‘object’ needs to be connected to the motor’s axle no further than 1.4cm from the axle.
Am I reading this correctly?
Bingo. Since the servo itself is physically larger than 1.4cm, it won’t be possible.
However, keep in mind that torque calculation is when the object is parallel to the ground (like lifting an object at arm’s length rather than stright up).
If you only plan to tilt the object over a small angle, the torque required would be less, but still needs to be calculated.

Do you know of other servo motor solutions with a higher torque (I’d say 150lb-cm)?
