1. NBR shaft seals on hardened cylinder barrels Drum motors axles are usually manufactured from ST37. Commercially available seals rotate directly on the axles. The result, at some point in time, is grooves on the axle. In addition of course oil leaks. This is not the case with the FTK Förderband Technik Kilian pulley motors all drum motors are equipped with hardened and polished cylinder barrels made of stainless steel 316. 2. Oil loss is not a problem for us! Oil change after 50,000 hours of work. Today, for reasons of cost, fewer and fewer users concern themselves with plant maintenance. The maintenance of complex plants is mainly carried out by outside specialists. Simple prefabricated parts, however, are usually used till worn out. This is also the case with drum motors. We have made allowance for this behaviour. The FTK Förderband Technik Kilian drum motors only require an oil change after 50,000 hours of work. In the case of operation with 3 shifts for example

easy adjustment for different stock widths and lubricants lubricant dispensation from the inside thru hollow axles – for an even spread series RB SF SW top roll adjustment with pneumatic cylinder

Pneumatic cylinder double acting Guided by 2 rods on ball bushings or bronze bearings Elastic damping at end of stroke Magnetic piston and Tgroove for sensor Robust and precise compact cylinder with guide Long and precise guidance because even for very short strokes, guidance is ensured by 4 bronze bearings or 4 ball bushings as the shortest body is the 50 mm stroke for lower strokes, a stroke limiting ring is placed in the cylinder. This guidance avoids the problems of buttressing, regularly encountered with ultrashort guides. These pneumatic cylinders are robust and reliable, even at high speed thanks to screwed cylinder’s covers (no circlips) an hardanodized body at 35 μ a thick front plate allowing a long centering of the rods for a better resistance to torsion Guided cylinder for universal detector The 5 / 6.5 mm Tslots allow the use of the majority of brands of magnetic detectors on the market. Stroke adjustment on compact guided cylinder

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.
