The ER-40eVo is our standard size retract system for models of up to 17kg (38Lb). It is the result of extensive evolution of the first version of our ER-40 which has quickly become the most popular electric retract in the world following its first release in 2007. The experience gained with the ER-40 has helped evolve and perfect the running and performance of this latest version, its main features being:
Compact design: The ER-40eVo main frame is milled from a single aluminium block, housing a spindle system with internal absorbers mounted between three bearings (two axial and one radial). All parts are very well protected inside the strong main body.
- Light, strong and precise: The main body is milled from a single block of 7075 T6 aeronautical aluminium. Electron uses the latest industrial milling machines allowing the highest accuracy on all parts, resulting a system that is strong, smooth and without play.
- Very easy maintenance: All rotating parts are made with self lubricating materials that require very low maintenance. Any damaged part can also be changed very easily. With just four screws you can completely disassemble the system and Electron Retracts can supply spares of all parts.
- Reversible: All retracts purchased from January 2015 are a reversible version: this means that it can be operated in normal or reverse mode. This version also accepts trunions with all retraction angles (from 70º to 105º). Following this manual or see this video, the customer can disassemble the trunion in order to change the direction of operation or of the retraction angle (in this second case a new trunion with desired angle will be necessary)
- NEW Square Spindle: this retract is now provided with a square thread spindle providing greater speed and torque to the system. Click here to find out more!
