Product Description QJ 309 PHASDetailed PhotosFour-point contact ball bearings can accommodate high axial loads in both directions and small radial loads. They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces. The outer ring, with ball and cage assembly, can be mounted separately from the two inner ring halves.High-speed capabilityAccommodate high axial loads in both directions and small radial loadsRequire considerably less axial space than double row angular contact ball bearings Product DescriptionDimensionsBore diameter45 mmOutside diameter100 mmWidth25 mmContact angle35 °PerformanceBasic dynamic load rating100 kNBasic static load rating83 kNLimiting speed12 000 r/minSKF performance classSKF Explorer Dimensionsd45 mmBore diameterD100 mmOutside diameterB25 mmWidthd1≈58 mmShoulder diameter inner ringD1≈81.2 mmShoulder diameter outer ring/ inner diameter housing washera51 mmDistance pressure point(s)r1,2min.1.5 mmChamfer dimension inner ringAbutment dimensionsdamin.54 mmAbutment diameter shaftDamax.91 mmAbutment diameter housingramax.1.5 mmFillet radiusCalculation dataSKF performance class SKF ExplorerBasic dynamic load ratingC100 kNBasic static load ratingC083 kNFatigue load limitPu3.55 kNLimiting speed 12 000 r/minCalculation factorA0.0202Limiting valuee0.95Calculation factorX0.6Calculation factorY00.58Calculation factorY10.66Calculation factorY21.07Company ProfileGuangdong Lingyi Industrial Technology Co., Ltd set up since 1997, with 20 years development, we become one of the best companies in the industry for mechanical and electrical products system integration, logistics service and investment.
