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.

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.

Rods for ball bushings and plain bearings Ø10, 12, 16, 20, 25, 30 et 40 mm Guide rods with tapping at both ends (except stainless steel just 1 side) 4 matters hardened steel, chromed steel, stainless steel 304L, hardened stainless steel Several lenghts and special length on request.

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)

U guide unit for pneumatic cylinders ISO Ø12 to Ø80 Antirotation guide on bronze bearings Protected by wipers seals Antirotation for ISO pneumatic cylinder This Light Series provides antirotation of the cylinder rod. With limited dimensions, it permits to use an ISO cylinder for shortstroke translations, while protecting the rod of the cylinder with its floating rod coupling. For environments requiring an anticorrosion version, the steel parts can be supplied in stainless steel (rods, coupling, screws), the body and the front plate are remaining in anodized aluminum (suffix /AC after the reference). For all stainless steel guides, refer to the 34*X series.

U guide unit for pneumatic cylinders ISO Ø32 to Ø80 Short guide on bronze bearings Protected by wipers seals Short guide for ISO15552 pneumatic cylinder This Classic Series provides antirotation of the cylinder rod. The guide is shorter than the H Classic series and is only available in plain bearings, so this series is recommended for low strokes and moderate loads. Anticorroding Uguide For environments requiring an anticorrosion version, the steel parts can be supplied in stainless steel (rods, coupling, screws), the body and the front plate are remaining in anodized aluminum (suffix /AC after the reference). For all stainless steel guides, refer to the 34*X series. Protection kit and back stop kit on Uguide The protection kit (tube wrapping the rods at the rear of the guide), for example allows to avoid a guarding housing on a semiautomatic machine (label maker …). The back stop kit, with hydraulic shock absorber, allows

For pneumatic cylinders ISO Ø8 and Ø10 Guide on bronze bearings or ball bushings The smallest guide unit in the range It’s the smallest unit, suitable for ISO6432 Ø8 and Ø10 pneumatic cylinders, allowing an ISO cylinder to be kept for small guided cylinder applications. It has a long Ushape to remain compact and have a guide length comparable to an Hshape. For environments requiring an anticorrosion version, the steel parts can be supplied in stainless steel (rods, coupling, screws), the body and the front plate are remaining in anodized aluminum (suffix /AC after the reference). Any special stroke is possible, with a maxi stroke of 200 mm.

H guide unit for pneumatic cylinders ISO Ø25 to Ø125 Very sturdy guide on plain bearings Protected by wipers seals Guide unit with large rods This Heavy Series has bigger guide rods than the Strengthened series. The thick front plate also allows long centering of the guide rods for better resistance to torsion. Only available in plain bearing version, it’s recommended for important radial loads in static. Sturdy guide for Ø125 cylinder Adapted to the ISO6432 (Ø25) and ISO15552 (Ø32 to 125) cylinders, this range therefore also makes it possible to meet the more robust guide needs for Ø125 cylinders, the guide rods then being Ø40, on 4 plain bearings. Anticorroding heavy guide For environments requiring an anticorrosion version, the steel parts can be supplied in stainless steel (rods, coupling, screws), the body and front plate are remaining in anodized aluminum (suffix /AC after the reference). Scrapers in polyurethane can be proposed for dusty or dirty environments.

Table for pneumatic cylinders ISO Ø16 to Ø40 Guided on ball bushings Protected by wipers seals More rigid than a H guide unit These tables maintaining the same quality of guidance and rigidity throughout the stroke. For a offcentered payload in vertical, these tables allow to be more rigid than a guide unit in H. Hydraulic shock absorber on this table A hydraulic shock absorber may be placed in opposition to the pneumatic cylinder to dampen, for example, the descent and/or limit the stroke at the output of the cylinder rod. The retracting stroke can be adjusted by the floating rod coupling. Use in harsh environment For dusty environments, additional nitrile or polyurethane scrapers can be added in front of the ball bushings. An anticorrosion version can be proposed with the rods, the coupling and the screws in stainless steel (the carriage and the plates remain in anodized aluminum). It’s possible to make these tables with plain bearings (bronze or polymer) on request.
