ive seen shattered ceramic crank bearings so i personally wont use them anywhere in my engines. check out skf explorers. theyre supposed to be one step better than a normal bearing. ive got some in my engine

 

 

 

 

SKF Explorer bearings – the new performance class from SKF

 

SKF Explorer is a new performance class of rolling bearings, of the types deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, spherical roller bearings, CARB toroidal roller bearings and spherical roller trust bearings, which provide a substantial improvement in key operational parameters relevant to the bearing type and its typical applications. This new level of superior performance represents the blending of SKF’s applications knowledge with its expertise in tribology, materials development, design optimization and manufacturing.

 

Using advanced analytical and modelling techniques and supporting testing, SKF engineers were able to confirm that SKF Explorer bearings provide a significant improvement in key operational parameters. These parameters, according to bearing type and application, include noise, vibration, service life, dimensional stability, dynamic load carrying ability and heat generation (frictional moment). Because these parameters are not adequately factored into standardized life calculations, SKF Explorer bearing life is calculated with modified factors, which takes key operational parameters into account.

 

SKF Explorer bearings are fully interchangeable with previously specified SKF standard bearings of the same type and size. These bearings are included in the relevant product tables and are easily identified by an asterisk (*) after the bearing designation.

 

The making of an SKF Explorer bearing

Achieving the outstanding levels of SKF Explorer bearings has only been possible due to the basic sound engineering design of SKF products and by further improving the manufacturing of bearings to these designs. By studying the interrelationship between each bearing component, SKF engineers were able to maximize the effects of lubrication and minimize the effects of friction, wear and contamination. To do this, an international research team looked at each component at micro level and then developed new procedures to consistently manufacture this new standard of excellence.

 

SKF Explorer bearings are characterized by a number of technical improvements, some of which are listed below. Depending on the type of the SKF Explorer bearing one or several of these below given examples have been applied:

 

Improved bearing steel

SKF Explorer bearings feature an extremely clean and homogenous steel with a minimum number of inclusions. This improved steel is so much cleaner than the highest grades covered by present classification methods that SKF has developed new calculation methods to take this factor into account.

 

The unique SKF heat treatment procedures

To maximize the benefits of SKF’s ultra-clean steel, engineers incorporated unique heat treatment procedures. These new procedures optimize the bearing’s resistance to operational damage without affecting heat stabilization. Wear resistance was improved so dramatically that SKF engineers were not able to accurately predict life expectancy using existing life factors for calculation methods.

 

Improved surface finish

The surface finish on all contact surfaces (rolling elements and raceways) has been improved to maximize the effects of the lubricant and reduce vibration and noise levels. This has lead to a smoother, cooler running bearing that uses less lubricant and consequently the arrangement, including the seals, requires less maintenance.

thats really interesting. great info didnt even know anything like that existed...

 

may mean you can run a 7 or 8 ball crank bearing and get the same load capacity of a 10 maxload with less friction???

 

might have to find a good bearing place and look into this more..
