Materials

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.

Materials

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.

In the field of special parts, we specialize in the manufacture of assemblies made of different material combinations as well as in the manufacture of other milled and turned parts, screws, nuts, thread inserts, etc. These products are made of different materials such as copper and aluminum alloys as well as partly steel and cast steel.

Types

Assemblies made of different material combinations
Milled and turned parts
Hot-stamped parts
Screws
Nuts

With over 150 active alloys we offer you a great range of materials - find the right solutions for your application.
