Technical seals

Technical sealsare a component of most machines, especially those used in the broadly understood construction and automotive industries. We are talking here about excavators, backhoe loaders, cranes, and even bulldozers, cars, trucks, agricultural tractors or specialized vehicles. So let’s learn more about this type of rubber products, dedicated to everyday and extreme applications.

Technical seals available from POWER Rubber

As we have already mentioned, we most often use seals of this type in the construction industry, but also more widely – in the automotive industry. And so, one of the most common places where we can find this type of seals are hydraulic systems (e.g. in the excavator arm for a tractor), rotary shafts located in the center of these elements, power steering pumps and most of the components with high pressure.

Purpose of the use of seals

After a brief reflection on where the sealing elements can be found, we can easily say that they have a protective and protective function. To a certain extent, thanks to them, we have the ability to operate machines, because they allow the controlled use of high pressures. These types of high pressure seals also retain oils, greases, hydraulic fluids and other aggressive chemicals.

Rotary shaft sealing rings

One of the basic seals are sealing rings used on rotating shafts. This type of gasket is one of the most advanced seals. They are also known as simerings. Depending on the place of use – whether it is on the arm of an excavator or backhoe loader, or as a component of a car engine, i.e. a shaft seal – the best type is selected. So let’s check what types of oil seals are available, i.e. individual types of technical sealing. The POWER Rubber Store offers the following seals:

Types of simering

As we already know, simmering sealing rings come in many variants. Here are the most commonly used and available for purchase from a technical seal store.

Depending on the selected variant, they are equipped with a spring.

 

Other simmerings have a metal insert in their construction.

Still other simmers combine these two components.

We can also find technical seals made of only rubber

Also, the higher model of the simering is equipped with an additional lip.

What is an additional lip for in simering?

We answer this simple question very specifically. An additional lip in the technical rings is used to trap dust and dirt. Its common name is an anti-dust lip.

O-ring – technical seals

O-rings, i.e. one of the basic technical seals, are round seals, called rubber rings with a wheel cross-section. They are most often used in places where the pressure is lower than in the case of simmerings, but also where resistance to temperature and contact with aggressive chemical substances, such as fuel and petroleum derivatives, e.g. pig iron or ozone, and widely understood gases are significant.

Rubber O-rings

O-rings types available at a rubber goods store

O-rings are the most commonly used seals. They are easier to produce for the Manufacturer of technical seals than the aforementioned oil seals. So let’s take a closer look at the types of O-rings available. Thus, the basic types of rubber rings are:

O-ring 50 on 3 NBR made of NBR
oring nbr

NBR o-rings

O-rings used in the temperature range: -40 ° C to + 90 ° C, basic resistance to oils and greases. They are also the cheapest seals. On the Polish market, offered in very low quality from importers from China – to high-quality ones are welcome to us?

O-ring 74 for 5 FKM made of FKM
FKM FPM Viton® O-ring

FKM FPM or Viton® O-rings

O-rings of this type are used as a better version of NBR O-rings – i.e. the seals described in the previous paragraph. IThe recommended temperature range by POWER Rubber Specialists is: -25 ° C to + 210 ° C. They are characterized by higher resistance, apart from high-temperature properties, also greater resistance to contact with chemical substances, such as: mineral oils and greases, or those containing components enriching their composition. Rings of this type are also resistant to hydraulic fluid, contact with propane-butane gas, fuels and crude oil. They are recommended for the automotive industry and production plants.

EPDM O-rings

EPDM O-rings are seals used in the temperature range -40 ° C to + 110 ° C, although POWER Rubber offers high-temperature EPDM seals – resistant up to + 150 ° C. These are seals dedicated to contact with water (if it is to be drinking water should be FDA certified O-rings, i.e. O-rings for contact with foodstuffs), DOT3 and DOT4 brake fluids, but also silicone-based brake fluids, i.e. DOT5. O-rings are also used for contact with esters and ketones.

O-rings Silicone

High temperature o-rings are silicone o-rings. They are used in the temperature range -60 ° C to + 180 ° C, although in the high-temperature variant they are resistant up to + 300 ° C. These are O-rings for the food industry thanks to the FDA certificate (with Food and Drug Administration source: https://www.fda.gov/ )- certificate of suitability of products for contact with foodstuffs. The manufacturer’s silicone O-rings can be of any size. In addition to the mentioned application, silicone gaskets are also used for contact with water, but at a low temperature and in industries such as medicine or pharmacy.

Covered O-rings, also known as seamless casing O-rings, i.e. rings in a FEP or PFA Teflon sheath, are used where increased chemical resistance is required. Often coupled with a wide temperature range, and even the aforementioned FDA food-contact approval. Coated gaskets are used in extreme cases and therefore are often a cheaper replacement for FFKM rings (commonly known as Kalrez®).
Depending on the use of the Teflon® lining insert, there are two main types for PFA O-rings:

Oringi PFA z wkładką wykonaną z FPM/FKM/Viton® stosowane w zakresie temperaturowym: 20°C do 204°C

FEP O-rings with a Teflon sheath Silicone, also known as VMQ and MVQ, is suitable for use in the temperature range: -60 ° C to 260 ° C
