SKF standard bearings – benefits

âž” fig ) andthe roller ends are surface treated to improve the effectiveness of the lubri- cant, reduce friction and lower opera- ting temperatures. The improved roller end/flange contact results also in high- eraxial load capability for those bear- ings with flanges on inner and outer rings. The optimal internal geometry provides• higher radial and axial load carryingcapacity, • higher operational reliability, • longer service life, • extended maintenance intervals, • lighter, more compact, energy-savingdesigns. The second improvement dealsspecifically with the roller end/flange contact. The geometry of the flange has an “opened” design (

ConventionaldesignEC design When an application calls for bearingsthat can accommodate heavy radial loads, high speeds and axial displace- ment of the shaft with respect to the housing, SKF single row cylindrical roller bearings are an obvious choice. These bearings are always state-of-the- artand they feature• an optimized cross section,• excellent contact conditions, • interchangeability of bearing components• cages made of three different materials and• a wide product range.The result is an assortment of cylind-rical roller bearings that will provide long servicelife even under the mostarduous operating conditions.

The optimized crosssection of SKF cylindrical roller bearings enables manufacturers to downsizetheir designs so that they aremore cost-effective, lighter and consume less energy, without affecting perform- ance.

Interchangeability of bearing components Optimized cross section

Another advantage of SKF single rowcylindrical roller bearings is that the bearing components are completely interchangeable. Any bearing ring with cage and roller assembly can be assembled with any removable ring of the same bearing type and size. This is particulary important with bearing components that have to be mounted independently of each other. The cross section of SKF cylindrical roller bearings is optimally utilized. The diameter and length of the rollers and the wall thickness of the rings and retaining flanges have been optimized to provide maximum bearing service life (

Optimal contact conditions

The internal geometry of SKF singlerow cylindrical roller bearings is specialin two very significant ways.First is the “logarithmic contact pro-file” between the rollers and raceways ( âž” fig ). This profile provides opti-mal load distribution between the roll- er and raceway, to significantly reduce the risk of edge stresses and increase operational reliability even in applica- tions where there is misalignment and shaft deflections.
