Our H guides can be adapted to many electric actuators of the market (with threaded rod or tapped rod). Also available in anticorroding version (AluStainless Steel)

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.

You can integrate any cylinder (type, standard, brand …) by using a cylinder rod coupling. You limit the number of parts by directly using a support of your frame and your end plate. A range of stainless steel guide bearings is also available Guide Type 34X You can also use bearing blocks

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.
