Conveyor technology plays a crucial role in the process of production automation. Because it enables prompt and reliable transportation of loads on a particular route, it is usually met in the shape of conveyor lines for transporting either raw material or products. Modular design enables numerous applicative solutions both simple and complex. Large capacities of heavy loads can be handled with minimum energy.

With the use of proper tools we significantly reduce the servicing time and ensure the correct instalment and the long term sealing.

In addition to the quality seals, we offer a variety of tools manufactured by quality manufacturers:

• The strip removal tool enables a quick and easy removal of worn braids from the grooves.
• With the strip cutter, the cutting of striped braided packings to the desired length and at the proper angle is very fast and easy.
• The three finger plier is a seal installation tool used for bending hydraulic seal without damaging it. It enables much quicker and easier seal installation.
• Silicon grease is recommended for use prior to installation of semerings, o-rings and other seals. Silicone grease protects and nourishes the seal, thus prolonging its life. At the same time it ensures correct and easy installation without damaging the seal.
• Seal removal spray is used for easier removal of tough gaskets and rubber seals. It cleans and prepares the installation place for the new sealant.
  We also recommend the use of various special sealing pastes, depending on application.

Machined seals are indispensable seals for engineers and maintenance technicians.
In our quick service workshop we are able to produce rapidly a unique custom- made seal in any size and shape!

Braided packings ensure reliable, cost –effective sealing both in linear and rotational applications as well as in the static sealing applications. They are used for sealing in valves, pumps, agitators and other rotary equipment. They are resistant to high temperatures, direct chemical exposures, vapour, abrasive materials, etc. Braided packing from our offer are produced from the newest and most advanced materials that meet different technological demands, from the applications with drinking water to the high standards of nuclear energy.

The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. A wide range of elastomers for standard and special applications enable its use in practically all liquid and gaseous media.
Our wide range comprises o-rings in different materials:

Our offer also comprises vulcanized o-rings and retaining rings.

Seals protect the machine elements against foreign particles and humidity. The right application and handling of seals extends the life of machinery, equipment and parts, thus contributing to their harmonious running. Seals prevent leakage while joining systems or mechanisms together. They can also maintain pressure or prevent contamination (eg. the pipeline system).The performance of the sealing element depends on the adhesion of the seal and the pressure.

Our wide range of seals comprises:

• Oil and rotary shaft seals
• O-rings
• Hydraulic and pneumatic seals
• Braided packings
• Gaskets
• Machined seals
• Other seals
• Tolls and other accessories
• Vibration dumpers
• itd.

We also manufacture non-standard seals from different materials NBR, EPDM, Viton (FKM seals), Silicone, Teflon and many others.

For urgent matters you can get the seal manufactured within 24hours!

Linear motors are widely used for a variety of linear positioning tasks. They are particularly suitable for higher speeds and frequencies of movements without backlash. In cases of higher speed and frequency of movements, linear motors are used as an efficient alternative to linear modules. Some linear motors may even run up to 30 metres.
Linear motors basically differ by the design of the core engine. They may be coreless or with an iron core. Position reading is possible with an incremental or absolute optical or magnetic encoder.

Our offer comprises a wide range of Hiwin high quality products. A TTL output signal is also available as well as the application of protection bellows.

Linear ball bushing bearings are designed to provide free motion in one direction although they also provide rotation. Because they provide low friction linear movement they can bear heavy loads. In most cases ball bushings replace sliding bearings made of bronze or sintered materials.

Our offer comprises a wide range of corrosion resistant stainless steel linear guides of standard lengths and ball bushings. For linear guides we also provide various forms of supports and final brackets.

We offer custom-made linear guides!
In our linear centre we cut linear guides to the desired length.

Linear guide rails and blocks are the basic components of linear technology that help support linear motion. They can lead load in all four directions and planes and due to their ease of movements and low friction resistance they are used to transport heavy loads.

Our range comprises different product families depending on the shape and load capacity. We also offer linear guide rails and blocks with anti-corrosion protection and linear blocks in a variety of shapes and fixing options, with ball roll system or rolling rail system. Miniature ball rail systems are also available.
Because each manufacturer manufactures a different rail profile, substitution of products is not possible.

In our linear centre, we cut linear guide rails to the desired length!

A retaining ring is a fastener that holds components or assemblies onto a shaft. It is used for the positioning and the protection of the machine parts.

Keyways are the machine elements used to connect a rotating machine element to a shaft. They prevent relative rotation between the two parts and may enable torque transmission. They are used in machine engineering and machine maintenance.

We stock standard retaining rings and keyway strips in all standard sizes.

A gear is a rotation machine part having cut teeth which mesh with another toothed part to transmit torque. An advantage of gears is that the teeth of a gear prevent slippage. They can enable higher gear ratios and have a very big practical value in general engineering.

Our wide range of gears comprises spur gear and helical gear spindles as well as spur bevel and helical bevel gears.

Gears can be of various materials: for less- load carrying capacity they are made of plastic and for bigger-load carrying capacity of metal. Due to the minimization of friction, worm gears can be made of a non-ferrous metal alloy.

As electric motors practically drive all machines they are applicable in all industries. They have high performance and are environmentally friendly as they do not pollute the air.
Our offer comprises Motovario and Elektroprecizia AC three phase asynchronous motors. They are designed for connection to AC power source.

A roller chain is the type of chain drive most commonly used for the transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery. It is a simple, reliable, and efficient means of power transmission. Roller chains can be power chains, load chains and transport chains. There are various types of load chains depending on the shape and the number of restraints, while the type of power chain depends on the number of parallel chain links.

We offer different roller chains with respect to the shape and the size of the chain link:

• Load chains
• Power chains
• Transport chain link

Belts are the cheapest utility for power transmission between shafts that may not be axially aligned. Belts help protect the machinery from overload. The belt drive is simple, they need no lubrication and require minimum maintenance. They have high efficiency rate (90-98%, usually 95%) and are of relatively low cost. As the demands on a belt drive transmission system are large, this has led to many variations of their use.

We offer only the belts of the top quality transmission belt producers!

Our wide range of belts comprises all standard and non-standard sizes and profiles, belts for special applications, belt linings and belt profiles for:

• GENERAL INDUSTRY: industrial belts are the most prevalent group of belts we know. Belts may be used as a source of motion to carry loads in different systems or to transmit power efficiently. In our offer you can find all types of belts such as V-belts, toothed belts, ribbed belts, flat belts, round belts, etc.
• AUTOMOTIVE INDUSTRY: we offer V-belts, toothed belts and ribbed belts for cars and commercial vehicles. We also offer belt tensioner kits.
