Rolled sliding bushing with solid lubricant
Three variants with different material compositions

The steel, lead, and bronze composition ensures high strength, while the solid lubricant content of around 25% ensures uniform lubrication. This is particularly helpful when the bearing is constantly subjected to tension, pressure, or changing loads.

Advantages:

• Very good wear resistance
• Stable lubrication even in continuous operation
• High load capacity in industrial applications.

Limitations:
Not designed for extreme heat like GETRO-TF-2. GETRO-09G offers more leeway for thin-walled constructions.

Conclusion: 
The rolled plain bearing with solid lubricant GETRO-08G is the robust all-round solution for classic industrial loads. Ideal if you need robust quality for demanding industrial environments – especially where loads and temperatures fluctuate frequently.

The bearing body is made of a bronze alloy (CuSn6.5P0.1 + Gr.), which is characterized by good elongation properties. This allows the bearing to be rolled out particularly thin – ideal if you have limited installation space. The integrated solid lubricant ensures that the bearing can be used in gear shafts or between clutch discs and the drive train without additional lubricant.

Advantages:

• Very thin-walled
• Highly formable
• Reliable lubrication in tight installation situations.

Restrictions:
Compared to GETRO-TF-2, lower load capacity and no reserves for extreme temperatures. In addition, only 65 N/mm² load capacity.

Conclusion: 
The rolled plain bearing with solid lubricant type GETRO-09G is ideal for designs with limited space – especially in gearbox and clutch applications where clean lubrication is required.

The CuFeNiSn alloy offers high strength, and self-lubrication remains stable even at temperatures up to +600 °C. This makes the GETRO-TF-2 type particularly suitable for industries in which thermal loads quickly overwhelm normal bearing designs.

Advantages:

• Very high temperature reserve (up to +600 °C)
• High load capacity
• Lower corrosion
• Reliable self-lubrication even under continuous exposure.

Limitations:
Technically oversized for standard applications and economically viable only if the heat requirement is actually present.

Conclusion: 
The GETRO-TF-2 rolled plain bearing with solid lubricant is the right choice for systems with extreme thermal requirements – for example, in railway and technology applications.

Since the lubricant is embedded in the material, risks such as lack of relubrication, clogged lubrication lines, or loss of lubricant due to heat are eliminated.

The solid lubricant is embedded directly in the material and is therefore permanently available. This completely eliminates the need for relubrication, and the bearing remains functional even when oil or grease would evaporate or be washed out at high temperatures.

Advantage of solid lubricant bearings:

• Independent of external lubrication, resulting in less maintenance and lower risk of failure
• Clean solution without oil or grease residues
• Reliable lubricating film even under heat, starting torques, or changing loads
• Stable dry running in areas where there is no space for lubrication lines

Limitations of solid lubricant bearings:

• Solid lubricant bearings are not always the first choice for extreme load peaks (depending on the type)
• For applications that run continuously and are sufficiently cooled, classic oil lubrication may be technically more advantageous
• The temperature range depends on the type (standard types up to +260 °C, GETRO-TF-2 up to +600 °C)

Conclusion: 
Rolled plain bearings with solid lubricant are useful if you need a reliable, low-maintenance solution that works independently of oil or grease lubrication. This is especially true in tight installation situations, in high temperatures, or wherever a failure of the lubrication system would have serious consequences.

• In GETRO-08G, the solid lubricant is arranged in a spiral pattern of diamonds on the bearing surface – these diamonds cover around 25% of the sliding surface and release the lubricant evenly as soon as the bearing is loaded.
• In GETRO-09G, the solid lubricant is distributed over the entire surface of the bronze structure, so that the bearing can be operated completely dry even with very thin wall thicknesses without the need for additional lubricants.
• In the GETRO-TF-2, the solid lubricant is integrated into a CuFeNiSn alloy designed for self-lubrication at extremely high temperatures – the lubricant remains available even at +600 °C and ensures that the sliding surfaces do not dry out or coke.

Advantage:

• Lower weight, as less material is used
• Thinner wall thicknesses, ideal for tight installation spaces
• Flexible formability, especially with the GETRO-09G type
• Uniform lubrication effect thanks to integrated solid lubricant

Solid bearings, on the other hand, are more useful when maximum point loads are required or the installation space does not allow for a thin-walled design.
