odel cylinders fabricated of aluminum.
- Is the insertion of objects through the center of the cylinder necessary as in tensioning or extracting operations? A center hole (hollow) cylinder should be chosen.
- Will the job require repeated cycling of the plunger as in a production application? The standard cylinder is for light duty, less than 2,500 life time cycles. Heavy duty industrial grade duty cycle cylinders are available from several manufacturers.
- And last, but certainly not least, how much plunger force is needed? How heavy is the object you wish to lift, jack, position, pull, or otherwise manipulate. Select a suitable cylinder capacity keeping in mind that an over-capacity margin should be applied.
