GEWA-K tubes offer a greater outer surface area compared to plain tubes. This is ideal for scenarios where the heat transfer surface coefficients vary significantly between the shell tube and the inner tube.

In GEWA-KS tubes, a special pattern is formed on the inside of the tube. This is ideal for scenarios with a low-heat transfer coefficient on the tube side, or an equally low-heat transfer coefficient on both sides.

GEWA-D finned tubes made of copper and copper alloys are available in a wide range of sizes and withstand the highest mechanical and thermic stress. They are specially made for the individual geometries of complex heat exchangers. Copper offers the highest heat conductivity of all technical metals. It is superior in processing, hygienic and a corrosion resistant solution.

GEWA-D finned tubes made of aluminium are specifically used in light-weight applications. Aluminium combines highest ductility with reasonable heat conductivity.

GEWA-D finned tubes made of carbon steel can be used in applications such as solid-fuel boilers or storage tanks. The significantly enlarged surface area compared to plain tubes allows compact solutions. Ready to install heat exchangers can be an interesting alternative solution for heat exchangers made of costly materials.

GEWA-D medium-high finned tubes made of stainless steel can be used for condensing boilers or domestic hot water applications. Due to the enlarged outside heat transfer surface area the required tube length can be reduced and thus costly material can be saved.

GEWA-H tubes are available in a wide variety of sizes, either in straight sections or as coiled heat exchangers. They are primarily used as heat exchangers in gas boilers and as oil and gas coolers in applications related to machinery and plant engineering.

GEWA-HB tubes are high-finned tubes with a fixed inner tube made of a different material. This allows for more corrosion resistant (premium) materials to be used in combination with other, less expensive materials.

Our W5000 round rods are our premium product for your high performance machining operations. We guarantee the minimum diameter variance in the one batch and a straightness of 0.55 mm/m up to a diameter of 80 millimetres.

New piston designs have become necessary due to legislation for pollutant emission of diesel engines. These design changes result in rising temperatures in the combustion chamber of the engine, with hot tensile strength and hot hardness of the bushings becoming increasingly important.

Bushings made of Wieland-SB8 and Wieland-SC5 are particularly suitable for the reinforcement of the piston eye.

Bushings in Wieland-SB8 and Wieland-SC5:

• are particularly suitable for aluminium pistons
• are wrought alloys (important: no casting) which are hot and cold worked
• have excellent hot tensile strength
• have outstanding oil corrosion resistance
• have dynamic load resistance up to 170 MPa, with Wieland-SC5 even more than 170 MPa.

Performance demands on steel pistons and connecting rods are constantly rising. For extreme loads Wieland-U17 is used. For medium loads also Wieland-SB8 can be used. With respect to connecting-rod bushings Wieland offers to do a PC calculation for the design.

Wieland U17 and Wieland-L67
Bushings for engines, in particular for pistons and connecting rods, should always be made of wrought alloys and not of cast alloys.

Wieland-L67 for machined bushings
Best press fit of all materials (press-out force equal to or higher than press-in force)

• Very good corrosion resistance
• Both alloys are wrought alloys
• Coefficient of expansion L66/L67, (20°C – 300°C) 18x10-6xK-1

Wieland-U17

• Excellent for steel pistons
• Load resistance (see link on the right)
• Excellent corrosion resistance
• Wrought alloy (important: no casting)

The very high pressures in axial piston pumps are a challenge for the material and precision of the parts. High-strength materials are increasingly being used for this application. Sleeves in Wieland SA5 is a special brass which has been specially developed for sleeves in axial piston pumps and successfully used in practical applications for many years. The addition of manganese and silicon results in the formation of hard manganese silicides making the material extremely wear-resistant.

Slippers in special brass materials Wieland-SA9 and Wieland-SB7

Slippers not only constitute high-precision bearing elements but are also exposed to extremely high stresses. The two special brass materials, which form hard silicides due to the addition of manganese and silicon and are therefore highly wear-resistant, also exhibit high fatigue strength. Due to these properties they can be used without problems under high dynamic load and at high operating temperatures.

Depending on the requirement, our solid lubricant pockets are designed for movement in axial and radial as well as for movement in two sliding directions at the same time. These solid lubricant pockets are made of different bearing materials such as Carobronze or Alcaro.

Benefits

• Maintenance-free / low-maintenance
• Cost savings (no costly lubrication systems)
• No contamination by oil or grease
• Seawater-resistant
• No stick-slip
• Temperature-resistant
• According to your specific drawing, information and quantity
• High flexibility through made-to-order production

Particularly suitable for medium to high load

• with simultaneously low sliding speeds, oscillating movements, intermittent operation
• in applications where oil and grease are not desired

Types

• Plain bearing bushes
• Thrust washers
• Bearing pads
• Drawing parts

Applications

• Mechanical engineering
• Automotive industry
• Steel works
• Rolling mill machinery
• Locks and weirs for surface and underwater engineering
• Industrial furnace manufacturing
• Food- and packaging machinery
• and much more

Plain slide bearings are used in slide bearing applications where adequate lubrication is guaranteed.

Possible designs:

• Slide bearings with plain surfaces and flange
• Additionally with grooves and holes for lubricant supply

The lubrication indents (ST) have different shapes in order to handle different lubricating assignments. Diamond-shaped lubrication indents are preferably used for grease lubrication, the spherical indents are used for liquid lubricants such as oil.

Advantages:

• Guaranteed function without frequent relubrication
• Deposit of foreign particles in the lubrication indents
• Can be reduced to any width without any disadvantages for the lubrication indents
• Better press fit and higher load capacity than LD bushings

Slide bearings with hole pattern (LD = long-term lubrication with depot) are suitable for all types of grease. Bushings with lubrication indents ST can easily be replaced by slide bearings with hole pattern LD.

Advantages:

• Significantly larger grease depot compared to bushings with grooves or lubrication indents
• Extension of the running time and the relubrication interval compared to ST bushings
• Collection of dirt and wear particles in the lubrication holes

Slide bearings with seals LDD/STD* can be delivered with seals inserted on one or both sides, depending on the application. This slide bearing type is specially designed for thinwalled slide bearings.

Advantages:

• Significant running time extension by optimal lubrication and protection against penetrating moisture and dirt in comparison to ST and LD bushings
• Minimal space requirements compared to standard seals
• Only one assembly part instead of different single parts
• Seals and slide bearings are 100% recycable
• Any common type of grease can be used
• Easy installation

*LDD = Long-term lubrication with depot and seal
*STD = Lubrication pockets with seal

The very high pressures in axial piston pumps are a challenge to the material and the precision of the parts. Therefore high-strength materials are increasingly used in the following applications.

Wieland SA5 is a special brass which has been specially developed for sleeves in axial piston pumps and which has been successfully used in serial production for many years. The addition of manganese and silicon results in the formation of hard manganese silicides making the material extremely wear-resistant. The lead-free alternative today is Wieland SX1.

Slippers are not only high precision bearing elements, they are also exposed to extreme high loads. The used special brasses, which form hard silicides due to the addition of manganese and silicon, have not only a very high wear resistance but also a very high fatigue strength. Due to these properties they can be used without any problems under high dynamic loads and at high operating temperatures.

K65 - Sustainable and efficient

Sustainable and efficient – two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO₂. Wieland supports this turnaround with a tube system that meets the high requirements of CO₂ as a refrigerant.

Wieland K65 tubes have been designed for CO₂ applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO₂. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).
