does anyone know of a good company to buy actuators from?
If you mean for pneumatics then you can use the 3 free bimbas and also buy from them.
If you are buying pneumatic actuator, best deal is with Bimba for the first 3 actuators, free with voucher, just pay shipping.
After the free ones, McMaster-Carr has a better price than buying direct from bimba.
where do you get the vouchers for the actuators?
thank you for the link to the voucher for the actuators
