You are bidding on a NEW ESCAP 22N2R Swiss Made Electric Can Motor Great for replacing open frame motors found in many brands of HO train locomotives. The Swiss built these motors like they make their wristwatches and clocks with high precision machined parts. This ball bearing front and rear coreless motor is super quiet running and powerful. Comes with a 16mm plastic pulley that is easily removable and a 1" piece of silicone rubber tubing to allow you to extend the drive shaft to a longer length if needed, see picture ( longer drive shaft is not included ). So if you want to upgrade your locomotives or have other projects that need a high precision motor try this one before they are all gone. Also great motors for robotics and science projects. Specs: 12 VDC, Shaft Dia. = 2mm, Shaft Length = 3.5mm, Diameter = 22mm ( about the same dia. as a US nickel ), Length = 31mm, If you buy more than one, please wait for the invoice to get a new shipping rate.
