The centering ring is built in at SITEMA and not removable (see Fig. 3: ”Application example for mounting without cylinder“). Ordering example for the centering ring: KFPA 040 016 - ZR 1 F is the nominal holding force for dry or hydraulic-oil wetted rods. The actual holding force is higher than F but will not exceed 2 x F. 2 The pressure required for releasing is 4 bar. The permissible operating pressure is 8 bar. 3 The bore hole is provided for a standard inductive proximity switch (M 8 x 1 with a nominal switching distance of 1.5 mm, flush mountable, NOC). 4 Pneumatic operating volume SITEMA GmbH & Co.

Technisches Datenblatt SITEMA Locking Units KFPA Locking by spring force / pneumatic releasing TI-F22-EN-05/2015 Operational purpose The Locking Unit KFPA clamps a rod in any position. It is commonly used to clamp the rod of standard cylinders according to ISO 15552 (corresponds to withdrawn standards ISO 6431, DIN ISO 6431, VDMA 24 562) or other rods independent from a cylinder. Locking Unit KFPA holds axial forces in both directions. Mounting The Locking Unit KFPA is prepared to be mounted on a cylinder according to ISO 15552 or to be used with a separate rod. Mounting without cylinder...

Technisches Datenblatt SITEMA Locking Units KFPA Locking by spring force / pneumatic releasing TI-F22-EN-05/2015 Axial play Choosing the right type The possible axial displacement in both directions is 0.1 mm. The table shows the nominal holding force F of the various types. The value of F must be higher than the maximum axial load acting on the rod. In case vertically moving masses shall be held or stopped or in case other dynamic impact forces occur, an appropriate safety factor must be applied. This factor has to be defined by the user depending on the requirements, but should not be...

The Locking Unit KFPA alone principally cannot form a complete safety solution. It is however suitable to be part of such a solution. Furthermore, all attachments and fixations have to be dimensioned correspondingly. This is generally the duty of the system manufacturer and the user. Operating conditions The Locking Unit KFPA is designed to operate in normal clean and dry workshop atmosphere. In case of heavy soiling conditions...
