Small Linear Actuator, High Speed up to 80 mm Per Second for Hospital Bed, Medical Traction, Nursing Bed

Picking a suitable actuator is more complicated than you think.For example, have you even consider the surface roughness of piston rod matters?We have to control the rod roughness that is not only for a smooth touch but coulddecrease the wear of seal rings which means it comes with longer-period waterproofprotection. As you know water or moisture is a ruthless killer for any electric productonce it creeps in. One unit of actuator is composed of hundreds of parts and any slightchange could bring 'butterfly effect'.Would you allow us to help?Though we have done a series of lab tests trying to simulate various of working environmentas much as we can, the applications are way more than we thought. Below table you can finda couple of questions which are very important. Our 10+ members of engineers could givesuggestion which model is right for you based on the info you offered.         Key Spec.Client's requirements ASupplier's offer        model# HB-DJxxx stroke    mmretracted length   mm (or not critical) => from front mounting hole to rear holevoltage    v dc (12v, 24v)load capacity    n (remark: 10 newton =1 kg)Push or Pull   Using pull force or push force?
