Air cylinder LDN / PVZ
On the selection of a clamping cylinder a criterion is if a through bore is necessary for bar machine or for clamping longer workpieces. In case of this, through bore clamping cylinders LDN are the best choice. If a through bore is not necessary, higher traction on the same air pressure with a PVZ is possible resulting of the design.
Our clamping cylinder LDN-HS is a speed optimized clamping cylinder with a through bore for highest speeds. Clamping cylinder LDN-A is a through bore cylinder with axial movable drawtube, which grants the simple activation of collets with a collet seat.
All LDN cylinders are a development of the LDZ series. Our customers e.g. from the optical industry or laser machining had the desire to operate the clamping system with oil-free instead of oiled air. Optimizations of the rotary distributor have enabled this to be achieved. The LDN cylinders are otherwise identical in external dimensions to the previously offered LDZ cylinders.
For the size the nececarry traction in association with the installation space is decisive.
