Self-lubricating sintered bearings made of graphite-containing sintered bronze
Sintered bearings made of graphite-containing sintered bronze are precision-manufactured plain bearings that are self-lubricating thanks to their special material structure. During manufacture, fine metal powders are formed with graphite under high pressure and then sintered at a controlled temperature. This process creates a self-lubricating material that guarantees maintenance-free operation even with the smallest movements.

Product description: Technical specifications and available materials
Our sintered bearings are manufactured to the highest industrial standards and impress with their durable, low-maintenance functionality. The special material structure and the precise sintering process ensure an optimal combination of mechanical strength and excellent sliding properties. This makes our sintered bearings ideal for demanding applications in mechanical and plant engineering.
Sintered bearings offer a number of technical advantages that increase both the operational reliability and the cost-effectiveness of your systems:
- Self-lubricating effect due to lubricants embedded in the material structure reduces maintenance requirements and lubrication intervals.
- Low-friction bearings for efficient movement and minimized energy losses.
- High load capacity for radial and axial forces.
- Temperature range depending on the material, usable from approx. –150 °C to +600 °C.
- Optimized wear behavior for long service life even under demanding operating conditions.
- Good corrosion behavior, especially for sintered bronze or nickel in humid or chemically stressed environments.
- Long service life due to uniform lubricant distribution during operation.
- Ideal for start/stop applications or angular movements.

Materials
Depending on the operating conditions and requirements, there are various sintered materials to choose from:
- Sintered bronze (CuSn) containing graphite or MoS2: good corrosion resistance, suitable for general applications
- Sintered iron containing graphite for high-temperature applications
- Special alloys: nickel-based for exceptional corrosion resistance, e.g., when in contact with acids
This variety of materials makes it possible to tailor sintered bearings precisely to your individual operating conditions. This allows you to benefit from maximum operational reliability and optimized service life for your components.
What makes sintered bearings from SL Gleitlagertechnik so special?
Sintered bearings from SL Gleitlagertechnik combine precision manufacturing with proven material technology. Thanks to their self-lubricating properties, they operate reliably and maintenance-free even under demanding operating conditions.
We manufacture your sintered bearings exactly to your specifications, even for single pieces, and guarantee short delivery times. Each bearing undergoes documented quality assurance, so you can rely on consistently high product quality.
This combination of technical performance, manufacturing flexibility, and fast availability makes our sintered bearings an economical and reliable solution for industrial use.
Difference to oil-impregnated sintered bearings:
While oil-impregnated sintered bearings have their advantages at high speeds, sintered bearings with solid lubricants show their strength at low to medium speeds (0.5 m/s) and high loads.
Start/stop and angular movements (making them well suited for bearings in positioning systems in automation technology) are also no problem for solid lubricant-lubricated sintered bearings, whereas these movements quickly overwhelm an oil-impregnated bearing because it cannot build up a sufficient oil film to support the shaft.
In addition, depending on the solid lubricant, applications can be achieved where no oil- or grease-lubricated bearing can still be operated safely.
What are the advantages of sintered bearings?
Sintered bearings are self-lubricating, low-maintenance, and offer impressive durability and reliability. They reduce maintenance costs, improve operational safety, and are ideal for applications where constant lubrication would be difficult or costly.
