Product Description QJ 238 N2MADetailed PhotosFour-point contact ball bearings with locating slots 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. The locating slots can be used to prevent the outer ring from rotating.High-speed capabilityAccommodate high axial loads in both directions and small radial loadsRequire considerably less axial space than double row angular contact ball bearingsThe locating slots can be used to prevent the outer ring from rotating Product DescriptionDimensionsBore diameter190 mmOutside diameter340 mmWidth55 mmContact angle35 °PerformanceBasic dynamic load rating510 kNBasic static load rating850 kNLimiting speed3 200 r/minSKF performance classSKF Explorer Dimensionsd190 mmBore diameterD340 mmOutside diameterB55 mmWidthd1≈244 mmShoulder diameter inner ringD1≈285 mmShoulder diameter outer ring/ inner diameter housing washera185 mmDistance pressure point(s)h12.7 mmLocating slot depth outer ringb10.5 mmLocating slot width outer ringr02 mmCorner radius locating slotr1,2min.4 mmChamfer dimension inner ringAbutment dimensionsdamin.207 mmAbutment diameter shaftDamax.323 mmAbutment diameter housingramax.3 mmFillet radiusCalculation dataSKF performance class SKF ExplorerBasic dynamic load ratingC510 kNBasic static load ratingC0850 kNFatigue load limitPu22.4 kNLimiting speed 3 200 r/minCalculation factorA1.77Limiting 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.
