333. Life3. LifeThe mechanical life of the actuator is represented by that of the guide receiving the greatest momentload.Operation life of the linear guide is to be determined by the total driving distance which can reachwithout having 90% flaking (peeling on rail surface).Operation life can be figured out with the calculation method shown below.3.1 How to Calculate Operaition LifeFor the operation life of the linear guide, use the dynamic allowable moment stated in 2. Specifications, andfigure out with the formula below.㻌㻌 L =㻌㻌㻌㻌䞉URL㻌㻌㻌㻌 L : Operaition life (km)㻌 C M : Dynamic allowable moment (N䡡m)㻌㻌㻌㻌 M : Moment to work (N䡡m)㻌 URL : Standard rated lifeIn addition, have a calculation for the drop of life with the formula below if there is a concern that the lifecould drop due to the condition of vibration or way to be attached.㻌㻌㻌㻌 L = 㻌㻌㻌㻌䞉㻌㻌㻌㻌䞉㻌㻌㻌㻌㻌䞉URL㻌㻌㻌㻌 L : Operaition life (km)㻌 C M : Dynamic allowable moment (N䡡m)M : Moment to work (N䡡m)㻌 fws : Standard operational coefficientf w :Load coefficient㻌 f䃐 : Attachment coefficient㻌㻌㻌㻌 URL : Standard rated life (km)Explained below is regarding the standard operational coefficient f ws , load coefficient f w, attachmentcoefficient f䃐 and Standard rated life URL.Refer to the contents below to set them up.[Standard operational coefficient f ws ]For ROBO Cylinders described in this manual, f ws = 1.2.
