  SEALING SCRAPERS

  <h2>Scrapers for sealing in hydraulics and pneumatics. Buy online at the best price</h2><p> Pneumatic and hydraulic cylinders work in a variety of applications and environmental conditions, such as exposure to dust, debris, or outdoor weather conditions. To prevent these impurities from entering the cylinder assembly and the hydraulic or pneumatic system, scrapers are installed.</p><p> <strong>Scrapers are linear dynamic displacement seals</strong> with a lip that are mounted at the end of the cylinder, specifically between the rod and the sleeve, they are used in this part of hydraulic or pneumatic cylinders <strong>to scrape dirt, external particles, chips or moisture from the rods, preventing it from entering said cylinders</strong> and the circuit oil network.</p><p> These prevent contamination of the hydraulic medium that can damage guide rings, seals and other components. The cylinders that make up the hydraulic group or the air installation need to operate in optimal conditions. The entry of contaminants, whether in greater or lesser volume, can have a great impact on the performance of the cylinders, potentially causing the cylinder to stop working in the system, which would mean an expensive repair.</p><p> The scrapers are basically made of NBR, polyurethane or with metal coatings and reinforcements. They can also be made of Viton for very aggressive environments. Each model is used depending on how it is assembled and its type of accommodation. The stem can have speeds of up to 2 meters per second without affecting its performance. They withstand temperatures of about 100ºC</p><p> Scrapers are used in any type of industry where cylinders, both pneumatic and hydraulic, are installed, they are easy to exchange and low cost.</p>

  SEALING SEALS

  <h2>Sealing seals. Buy online at the best price</h2><p> Radial seals are circular-shaped elements, mechanical seals manufactured to prevent leaks or the unwanted exchange of fluids, gases or solids. Normally, the elastomer membrane has a spring on the vertical of the sealing edge to maintain the tightness of the shaft, whether in operation or not.</p><p> This circular spring is responsible for ensuring that said lip does not expand and guarantees good sealing. There are different types that are used depending on the required application where the temperature, components or contaminants may vary.</p><p> There are metal seals, since their casing is completely metal and the inner lip is made of elastomer. They also exist with double lips, that is, with two lips and two springs to prevent both directions or bands from leaking or losing. The classic seal is the one that has an inner lip with its spring and a dust lip to prevent particles or dirt from entering the system. On the other hand, the fluids to be sealed are liquids of variable viscosity. They are not usually gases. Most commonly, these are lubricants, such as oils and greases, but also hydraulic oils (according to DIN 51524), non-flammable pressure fluids (according to VDMA 24317 and 24320) and even silicone oils with poor lubricating properties.</p><p> The seals create a seal between the rotating shaft and the outside. Classic seals consist of a metal casing that carries the dynamic sealing lip and also provides the static sealing function. The sealing lip of the seals is generally made of elastomeric material, and is in contact with the surface of the rotation shaft. Here, the lip is pressed to the surface of the shaft by means of a spring ring. As a result of the rotary movement, a sealing gap occurs at the edge of the lip. Oil can penetrate into this void, which serves to lubricate the sealing lip.</p><p> The seals can withstand radial speeds of 14 meters per second. They withstand temperatures of up to 100ºC and even much more depending on the material manufactured. They can be made of NBR, Viton, silicone, fluorocarbon, PTFE and other derivatives. The seals are mounted in practically all types of industry, they are easy to exchange and are economical. There is a wide variety of measures that can be applied in any system.</p>

  V-RING JOINTS A

  <h2>V-Ring joints. Buy at the best price</h2><p> <strong>V-Rings</strong> are elastomer rings that provide sealing of the rotating axles in the absence of pressure. As is the case of a retainer. They are used to ensure the seal against dust, mud, water, oil, etc. The V-Ring joint remains stable on the shaft, rotates with it and is commonly used in the machine tool, household appliances, electric motors, and switches sectors. , mining, cars…</p><p> It has a dynamic closure, which is made from the flexible lip that rests on the metal part orthogonal to the axis of rotation. While it is in this rotation process, the centrifugal force projects the droplets away from the device, thus preventing their exit towards the surface that must be protected.</p><p> The V-Ring gasket also makes a combination of lip closure and the mechanical and centrifugal effect against external agents, whether liquid or solid. V-Rings have very characteristic advantages, such as supporting the joint and the shaft, due to their low friction. The finish of the metal parts does not require a high degree of surface treatments. Made of NBR, they have a hardness of 50 Shore and can withstand temperatures between -20ºC / 100ºC</p><p> Its use is widespread in all types of industry and machinery and its assembly is very simple and the cost is low.</p>

  PISTON GASKETS

  <h2>Piston seals. Buy at the best price</h2><p> <strong>Piston seals are a type of seal used in hydraulic and pneumatic cylinders for fluid sealing</strong> . They are housed inside the cylinder head and achieve sealing against the cylinder rod, preventing the fluid from flowing through the cylinder head and one chamber communicating with the other. This allows pressure to be generated on one face of the piston, causing the cylinder to extend or retract.</p><p> Piston seals are usually double acting. There is a wide range of piston seals that provide good leakage control. They exist in two pieces, made up of an O-ring or square seal and a guide on the outside. There are those that are made in a single piece, widely used in pneumatic cylinders. There are also 3-piece ones, consisting of an NBR sealing element reinforced with canvas that gives it high mechanical strength and two thermoplastic support guide rings.</p><p> The set has very good resistance to abrasion, compact shape and simple installation. Also available are the five-piece ones, consisting of a multi-lip NBR sealing element, two rings on both sides to prevent extrusion in the sealing groove and two other guide rings to absorb transverse forces.</p><p> A piston seal is mainly made of NBR + TPE + POM. Manufactured specifically for hydraulic applications, these compounds provide exceptional wear resistance and extraordinary extrusion properties. Compatible with virtually all media, they offer unparalleled performance at extreme temperatures. Effective sealing during vibration and shock loading. Superior sealing effect at high pressures. Maximum sealing efficiency with the least friction.</p><p> Piston seals for hydraulic cylinders are used for heavy loads, steel industry, excavators, cranes, naval hydraulics and loading platforms and in general in all types of industries where hydraulic cylinders have applications. Pneumatic piston seals are used in systems where there are low pressure pneumatic cylinders.</p>
