Hello Robot Shop,
I am interested in purchasing your ServoCity Vertical Shaft 30:1 Worm Gearbox RB-Sct-336 for a new Retractable Lamp Design I am working on for a major Manufacturing Firm (Steelcase Corp.), but will need some Technical Assistance in selecting the Motor? This Worm Gearbox is a perfect size and function due to the fact that there is no Backlash and can hold the Lamp Arm (approx. 6 Lbs.) in any position when the power is off, am I correct?
Anyway, the Motor I need (Servo, Step, Geared or Synchronous) in combination with the 30:1 Worm Gearbox will need to give me a final Revolutions of +/- 7 RPM, can you suggest a 110V AC Motor?
One concern, what is the Product Life Status on this Worm Gearbox RB-Sct-336, I checked the ServoCity Web Site and could not find any information on this Product? My Proposal to Steelcase has a prerequisite that I can guarantee my design with a Product Life Status for at least 2 to 3 Years and they requested Price Breaks of 50, 100 & 500 Quantities. I will need an immediate 3 Samples of the Worm Gearbox & selected Motor as soon as possible for my Prototype, can you confirm?
I hope we can work something out, please forward pricing and availability for the Worm Gearbox and Selected Motor right away?

The Vertical Shaft 30:1 Worm Gearbox is designed specifically for use with a series of spur gear motors and is not directly compatible with stepper or AC motors. Unfortunately we do not carry any AC motors, nor do we have any suppliers to suggest (let alone any which may have the appropriate mounting pattern, shaft position and diameter). The easiest solution would be to choose the appropriate DC gear motor and use a wall adapter (110V AC to 12V DC). Several can be found here: robotshop.com/en/spur-gearmo … =ServoCity robotshop.com/en/spur-gearmo … and=Pololu
The mechanical durability of the system depends on the load and frequency of use. As such, it is not easy to confirm how / when the unit will fail, but it is likely the motor which will encounter issues first.
Pricing ($59.99 for the gear box system without motor) and availability are online. We currently have two in stock (as of July 4, 2016), and can get new stock in ~2 weeks.
