This item is a viscous rotary damper used for making your own dethermalizing timers. I have not been able to find them for sale elsewhere in small quantities and had to resort to buying large minimum orders. I keep what I need for my own models and offer the rest here for anyone that can use them. This is the smaller 'Button' version with a pull force of 1.39N. Gear included. Click on the 'more information' link for a little video on making springs for these dampers.

For orders outside the US: If you only get "Global Express" as a shipping option for a gozillion dollars, go ahead and place the order along with a note saying you want "Global Priority" shipping instead. I will make the adjustment on my end PRIOR TO CHARGING YOUR PAYPAL ACCOUNT.
