Before the plugin assembly, both clamping ring hubs must be fastened to the shafts with the correct tightening torque. Lightly oil the spider to ease assembly. Assembly The shaft to hub bore fit should be a transition fit. The play should be max. 0.02 mm. i.e shaft Ø 25 k6 bore Ø 25 G6. Bores smaller than D1/D2 min. are possible, however an optimal transfer of the nominal torque is no longer guaranteed. On request Hub bores D1 and D2 with separate tolerance class or range.

Zero backlash, torsionally rigid, resiliently flexible and maintenancefree full metal coupling for transmitting angle synchronous rotary movement. The innovative slit structure makes possible a very good axial, radial and angular flexibility with low reset force. Ideal for servomotors. Assembly Recommended shaft tolerances h7. On request Hub bores D1 and D2 with separate tolerance class or range. Note Procedure for enlarging predrilled bores D1/D2 Drill the bore out using a small as possible drill or milling cutter. Use a single point tool to turn or bore the hole out to its finished size. Ensure that the coupling is securely held during the machining process and that the drill feed is not too high. The cut depth should not exceed 0.5 mm and the feed for the single point tool should also be not too high.

Centre disc polyacetal. Hub aluminium. Note Clamping the hub with a grub screw is a costeffective alternative to the Oldhamtype couplings with radial clamping hub (23030). Short mounting times. The couplings can be mounted completely assembled or a plugin assembly is also possible. Take note of the tightening torque for the grub screw. To ease removal we recommend milling a flat on the shaft. Assembly The shaft to hub hole fit is a transition fit. The play should be min. 0.01 mm and max. 0.04 mm i.e. shaft Ø 6 f7 hub Ø 6 H8. Advantages robust plugin playfree short design On request Hub bores D1 and D2 with separate tolerance class or range.

Floating rod coupling for pneumatic, electric or hydraulic cylinders Zinc steel or stainless steel 304L With axial play or adjustable play Floating coupling for cylinder rod These rod couplings make it possible to connect the rod of a pneumatic cylinder (or electric) to any part to be set in motion while avoiding any stress on the rod. They are available in 2 versions . with axial play (<0.20 mm) usual pneumatic applications and for pushing applications . with adjustable play for positioning applications => The version with axial play allows a radial compensation of the axis of the cylinder rod, it’s for usual pneumatic applications => The version with adjustable play allows the axial play to beRod coupling with adjustable axial play – reduced by screwing the cylinder rod against the internal pin and then unscrewing it slightly (then lock with the cylinder rod nut against the coupling) – removed by screwing the cylinder rod against the internal part (with tightening)

For electric cylinders ISO 15552 size 32 to 100 Selfcentering rod coupling without axial play adapted to positioning Principle of rod coupling with reduced axial play Rod coupling with adjustable axial playThe difference with the ISO 15552 pneumatic cylinder guide units is at the level of the cylinder rod coupling on these guides for electric cylinders, the selfaligning rod coupling has no axial play (or a reduced axial play) depending on the assembly carried out, these units without axial play are therefore suitable for positioning applications. For applications without positioning accuracy or with high radial loads in static, it’s possible to use the guide units for pneumatic cylinders with a guide on plain bearings, since the rod coupling has an axial play (<0,2 mm). Guides for nonISO actuators For electric actuators which are not ISO, we know how to adapt our guide units to most of the rod actuators on the market see Hguide for actuators.
