Sliding bushes, sliding plates &
Guide bushes
Specialist for copper alloy plain bearings in special shapes and sizes
The best guides are the ones you don’t have to worry about!
We have the material for it. ALBROMET-A200 is a high-strength aluminum bronze (copper alloy) for guide bushings, plain bearings and sliding plates in special production.
The machine components made from it have excellent sliding properties, high strength and outstanding emergency running properties.
They therefore ensure a long service life.
They still work with conventional materials as wear partners?
Then convince yourself of the excellent results from this material.
- Very good sliding properties
- High compressive strength
- Minimized friction due to smooth surfaces
- Very good emergency running properties
- Corrosion-resistant to many media
- Low-lubricant components available
- Special dimensions according to drawing are manufactured
The correct choice of material for guide and sliding elements depends on the application and the respective operating conditions, such as load, speed and operating environment. Precise manufacturing is crucial to minimize play and ensure exact guidance. Correct lubrication reduces friction and extends service life. These components therefore make an essential contribution to the performance and longevity of mechanical systems.
ALBROMET aluminum bronzes and copper alloys are ideal for manufacturing these components in high quality or with an optimum surface finish. Another advantage is their high corrosion resistance to a wide range of media. ALBROMET aluminum bronzes can therefore also be used for sliding elements that come into contact with industrial water, seawater or chemicals. The aluminum bronzes ALBROMET-A200 and A260Ni as well as the high-strength copper alloy W200 are also approved for the food industry.
Self-lubricating or maintenance-free guide bushes, Slide bearings and slide plates
The aluminum bronzes are ideally suited for the insertion of graphite balls or Teflon balls for low-lubricant gliding.
The version with Teflon bearings is also approved for use in direct contact with food under the brand name “Health Glide”.
Certification by an independent testing institute is available.

Answers to frequently asked questions
Aluminium bronzes are used in all machines and systems in which the friction of moving parts is to be minimized.
They are the ideal friction partner for all types of steel.
Both strength, modulus of elasticity and compressive strength are very high.
With good lubrication, friction and wear are very low.
Adhesion does not occur when paired with steel due to the different materials, which also means good emergency running properties.
The heat generated by friction is dissipated well due to the high thermal conductivity of aluminum bronzes.
Plain bearings in machines usually need to be lubricated to ensure their functionality and increase their service life.
However, there are also special maintenance-free variants that do not require additional lubrication.
The choice of the appropriate bearing and lubrication method depends on the specific requirements of the application, the operating environment and the maintenance requirements.
A distinction is made between dry-running bearings, solid lubricant bearings and lubricated plain bearings with continuous oil lubrication via lubricant pockets.
Lubricants reduce the friction between the bearing surfaces and the moving parts, which increases the efficiency of movement and reduces energy consumption.
Lubrication minimizes direct contact between the metal surfaces, which reduces wear and extends the service life of the bearings and the machine.
In addition, lubricants help to dissipate the heat generated by friction, which prevents bearings from overheating and thus avoids damage caused by thermal stress.
Finally, lubricants provide some protection against corrosion and rust formation by shielding the metal surfaces from moisture and other corrosive substances.
Compared to rolling bearings (ball bearings or roller bearings), plain bearings have a number of advantages that make them particularly suitable for certain applications.
- Plain bearings have a simpler design without moving parts such as balls or rollers.
They mainly consist of a bearing bush and a shaft.
As a result, plain bearings are generally cheaper to manufacture and purchase than roller bearings. - Plain bearings can distribute high loads evenly over a large area, thus avoiding point loads.
They are less sensitive to shocks and impacts, which makes them particularly suitable for applications with alternating or shock loads. - Plain bearings require less installation space than rolling bearings, as they do not need additional components such as cages or rolling elements.
- Slide bearings can be more easily adapted to specific spatial requirements.
- Plain bearings are also available as low-maintenance variants with self-lubricating materials such as PTFE (Teflon) or impregnated with solid lubricants.
The manufacture of plain bearings involves various techniques and processes that make it possible to produce bearings with different properties, shapes and sizes.
The following process selection is defined by the material used:
- Casting
- Sintering
- Mechanical processing (solid plain bearing)
- Extrusion
- Rollers
- Injection molding
- Coating
- Additive manufacturing (3D printing)
ALBROMET specializes in solid plain bearings made from aluminium bronze and copper alloys.
These normally consist of a single bearing material.
Plain bearings are often provided with lubrication grooves, pockets or channels.
Oils, greases or oil-free lubricants are used for lubrication (cf.
our cooperation with LBI oil free).
