    How to choose a cylinder

    2022.09.02

    The relationship between the output torque of the motor and the output force of the cylinder  F=T*2π*R/L*N
    F：Cylinder output force，Unit:KN，T：Motor output torque，Unit：N.M ；R：Reduction ratio
    L：Screw lead，Unit :mm

    N：Efficiency, the total efficiency of the general cylinder is 85%, but the efficiency will vary according to the actual operating conditions.


    Cylinder lifespan 
    The lifespan of the cylinder generally refers to the lifespan of the lead screw used inside the cylinder, which can be divided into two parts, one is the fatigue life of the lead screw, which can be calculated: the second is the working lifespan, depending on the conditions of use (input temperature, gray level, the type of lubrication used and the frequency of regular addition, etc.), the working lifespan is often obtained through experience, the following is the calculation method of the life of the cylinder.
    L10=(Ca/Fm)3*S
    L10:Lifespan of the cylinder，Unit：KM

    Fm：Average load on electric cylinder，Unit：KN
