Plain bearings - Import export

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.

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.

Hguide unit for pneumatic cylinders ISO Ø25 to Ø125 Sturdy guide on ball bushings or bronze bearings Protected by wipers seals Sturdy Hguide This Strengthened Series has bigger guide rods than the Classic series and a thicker front plate for longer centering of the rods to increase torsion strength the plate / rods connection is generally the weak point of the Classic series when offcentered forces or loads are applied. Guide unit for Ø125 cylinder Adapted to the ISO6432 (Ø25) and ISO15552 (Ø32 to 125) cylinders, we can also adapt other types of pneumatic cylinders or electric actuators. Sturdy guide on plain bearing or ball bearing ? The plain bearing version is recommended for static radial loads, short strokes, dusty environments, it’s also the more economical version. The ball bushings version is recommended for precision (no radial play), high loads at horizontal, long strokes and offcentered loads. For critical applications, we propose Heavy series.

H guide unit for pneumatic cylinders ISO Ø12 to Ø100 Long guide on ball bushings or bronze bearings Protected by wipers seals H guide unit according ISO standard This Classic series of linear guide unit is the most common on the market. It ensure the guiding and antirotation of the payload, the floating coupling protects the rod of the cylinder from any mechanical stress. Adapted to the ISO6432 (Ø12 to 25) and ISO15552 (Ø32 to 100) cylinders, we can also adapt other types of pneumatic cylinders or electric actuators. Guide unit on plain bearing or ball bearing The plain bearings version is recommended for static radial loads, short strokes, dusty environments, it’s the more economical version. The ball bushings version is recommended for precision (no radial play), high loads at horizontal, long strokes and offcentering loads. For critical applications, we propose Strengthened and Heavy series and for simple antirotations, you can opt for Useries, Classic or Light.

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.

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.

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

Compact and economical linear guide unit for ISO 15552 cylinder Ø32 to 50. Short guide on bronze bearings, ball bushings or polymer bearings. Competitiveness of guide units for ISO 15552 cylinders This range is very competitive since it is 25% less expensive than a HGuide Classic Series 20% less expensive than a UGuide Classic Series 10% less expensive than a UGuide Light Series (comparison made on size 4 – for cylinder Ø32) Area of application of compact guide units These compact guides being available in ball bushings whereas all the Uguide units are generally available in plain bearings only, they are particularly interesting for simple applications at high speed like in packaging machines. It will also be used in tight spaces, but for short strokes (<100 mm), it may be advisable to use a compact cylinder ISO 21287 with the guides
