I have the opportunity to buy some Hiwin Rail/carriages really cheap locally, but I am unsure if they will be suitable.
I have searched online and found many differing opinions.
Basically I am unsure if the preload will be suitable. They are HGH20 carriages with light preload, and I plan to use 4 of them on a Z axis. I don’t know if I’m overthinking this or not so would value any input.
Does anyone know if they will be up to the job? The price is too good to refuse really, but if they will be unsuitable it defeats the object of buying them.
