Tribology is the Science of Friction, Wear and Lubrication
Find out how GGB's antifriction products and solutions offer improved bearing performance for your application.
GGB's antifriction plain bearings and bushings provide numerous benefits across a wide range of industries and applications, including aerospace, automotive, construction, energy, industrial, recreational and many more.
With the constant increase in customer demands and expectations for superior plain bearing performance, GGB's bearing range now includes over 50 distinctive antifriction bearing types including for example, DP4, HI-EX®, GAR-MAX®, HSG, EP™ range, GGB-CSM® and GGB-CBM® products.
To Eliminate Lubricants, can GGB bearings operate dry?
The range of self-lubricating GGB bearing products are ideally suited to run under dry conditions offering to the final customer complete maintenance-free operation.
The main advantages are:
- Reduced cost with simplified designs and assembly by eliminating lubricants
- Increased machine utilisation and efficiency with fewer stoppages for regular bearing lubrication
- More environmentally friendly operation as potential pollution by the lubricant is avoided
When do GGB self-lubricating bearings operate with a lubricant?
Self-lubricating bearings are also necessary when operating under boundary or marginally lubricated regimes.
These regimes occur when the thickness of the lubricant film is too low to avoid metal-to-metal contact and wear between the bearing and the sliding surface due to a combination of high loads, low speeds and insufficient lubricant viscosity.
For equipment running under periods of low speed idling and frequent stop-start operation, the self-lubricating properties of GGB bearings significantly improve machine efficiency by reducing bearing wear and the increase of clearances, noise and the risk of eventual equipment seizure.
How can GGB bearings Improve Machine Efficiency?
The majority of GGB bearings contain polytetrafluoroethylene (PTFE) in the sliding layer.
One of the characteristics of PTFE is exceptionally low coefficient of friction which reduces bearing friction, bearing wear and, most importantly, energy consumption.
The overall efficiency of equipment and machinery is therefore increased for reduced power input and a higher power output.
How can GGB bearings Extended Service Life?
The proprietary GGB bearing structure and overlay compositions include special anti-wear additives for high wear resistance to give extended service lives.
What are the advantages of Replacing Roller Bearings?
Compared to roller bearings, plain bearings offer a greater contact area for a higher load capacity, an excellent resistance to shock loads and are more tolerant to edge loading.
The compact one piece design of plain bearings allows a significant reduction in housing dimensions for substantial space and weight savings.
Noise is reduced with the absence of internal moving parts and the plain bearing conformable liner offers superior damping properties.
