Technical characteristics A spring in special steel, developed together with FEA (Finite Element Analysis) and with the assistance of the most advanced CAD technics, constitutes the heart of this new locking unit which, in addition to the excellent locking capacity and repeatibility, enable a soft braking of the moved masses. Main performances and characteristics: * For release pressure values under 4 bar, the reaction of the locking unit cannot be foreseen. Braking distance In some applications, it could be necessary to know the piston rod stroke between the reception of an emergency This value...

L6 series locking unit for rodless cylinders Locking unit The UNIVER locking unit for rodless cylinders has been realized with the aim to stop the carriage in any point of its stroke and it is able to provide a good locking precision. It is possible to assemble it indifferently on either side of the carriage and its mechanical braking force may be further amplified by means of an additional pneumatic control.

Technical characteristics Examination and verification of the cushioning In a system with moving masses, as in the case of rodless cylinders, it is essential to control the dissipation of the system's kinetic energy as it is brought to a stop. It is necessary, first of all, to establish and verify the most suitable method of cushioning the system, in order to avoid the moving mass (carriage with load) striking against the end-caps and compromising the life of the cylinder. If the point corresponding to a given load and speed lies beneath the appropriate curve, the cushioning is able to absorb...

If it is not possible to absorb the kinetic energy with the cushioned end-caps and modify the parameters (a-b-c shown at page 11), an additional cushioning is necessary to reduce the load speed before the cylinder strikes the - a pneumatic cushion with electronic control; - a hydraulic cushion, available on the market. The mass movement generates loads to the cylinder, connected both to the weight forces (load values are constant) and to the inertia forces which originate in the acceleration or deceleration phases of the piston at the A typical fatigue stress arises in which the load value affects...

Values of the static load; please note that under dynamic conditions the load must be reduced due to the effects associated with the speed. The torque is the prod uct of load (Newton) per arm (meters), i.e. the distance between the center of gravity of the load and the longitudinal axis of the piston (technical characteristics see page 11-12- ).
