New NEMA 17 stepper motor with optional integrated lead screw
- 12 June 2017Hello, Jan.
The datasheet for the stepper motor, which can be found under the "Resources" tab on the product page, gives a maximum axial force of 10N. Our expectation is that the axial load rating already takes any such bearings into account, making it equivalent to a linear force rating.

- 20 March 2017Hello, Vincent.
Can you characterize how much rolling resistance you are seeing?

New Product: 5V, 5A Step-Down Voltage Regulator D24V50F5
- 3 June 2016Hello.
The mounting holes on the board are 0.85" from edges they are closest to. We do not have a dimension drawing for this board yet, but the DXF file has all the hole locations on the board.

Two new motor driver shields for Arduino
- 5 May 2016Hello.
I am sorry you are having a problem with your motor driver shield. This is not an appropriate place for troubleshooting, but if you post about the issue on our forum with more details, like which driver you have, we would be glad to help.

37D mm metal gearmotors with encoders and end caps
- 25 April 2016Hello, Jason.
The shaft is supported by a bushing (sleeve bearing). We do not have any specific radial load ratings for these, and in general, more radial load will lead to shorter life. We do not recommend more than a few pounds of radial load on the output shaft.

PiBot-A: mobile robot with a Raspberry Pi
- 3 December 2015Hello.
Thanks for the suggestion. We have a few laser-cut plates that would probably work with the Rasberry Pi, but nothing in that exact size. We'll keep your suggestion in mind! For now, you could check out our custom laser cutting service.

New high-current stepper driver carrier with SPI: AMIS-30543
- 8 September 2015Hello, Giacomo.
StepStick is a brand of stepper motor driver carrier that we do not make or carry. The AMIS-30543 stepper motor driver uses different signal inputs than the A4988 and DRV8825 and will probably not be compatible with shields designed for those stepper motor drivers.
