Product Name: F20 Deep Groove Ball Flexible Bearing for Harmonic Drive Reducer High Precision Model NO.: F20 Material: Bearing Steel Rows Number: Single Aligning: Non-Aligning Bearing Contact Angle: Single Row Ball Precision Level: P6 P5 P4 Trademark: YDPB Transport Package: Carton Origin: China HS Code: 8482800000 Product Description Industrial robots bearingsRobot bearing/harmonic drive bearing is a special kind which easily deforms in a reversible way. It has a very thin outer ring which varies from round shape to oval interatively during its working time. easily double sealed bearing designed primarily for application of radial load-deep ball grooves also permit application of thrust load in either direction, often used in conjunction with another bearing.Note: Some bearings we have use new structure( with cage and cover,convenient for you to install)Other DimensionIndustrial Robots Use Flexible Bearings Regular modelsWith cage or both with cage and coverModelOuter ringInner ringDBall diametermmBall QtyZDynamic load ratingCrStatic loadratingCorRadial Deformation Max. mmInputrotate speed r/minOutput torque N.mODWidthBIdWidth CE904KAT225418.842.381233.753.120.2300023E905KAT23252453.175234.743.750.2300063E806KAT24063063.5237.125.830.33000161000907AKIT248.2835.884.5239.938.360.33000303E907KAT25083784.7632312.63120.33000303E809KAT26094595.5562312.8911.550.43000501000809AKIT261.89.545.795.5562312.8911.550.430005010008810AKT2639.7489.25.5562312.8911.550.43000501000912AKT2801260127.1442327.1928.180.53000120F1433.8966.09525.076.353.175234.743.750.230008F1741.7226.1630.36.683.969237.125.830.3300016F2049.0737.2435.568.134.763239.938.360.3300030F2561.3419.01545.2126.355.5562312.8911.550.4300050F3279.75611.8158.9288.647.52322.2820.910.53000120M1433.8966.09525.076.353.175295.534.730.2300012M1741.7226.1630.36.684288.317.350.3300024M2049.0737.2435.568.1343312.63120.3300045M2561.3419.01545.2126.355.5563016.416.580.4300075M3279.75611.8158.9288.6473127.1928.180.53000180Industrial Robots Use Flexible Bearings Regular modelsWith cageModelBoundaryDimension(mm)DeformationRated speedRated torqueRating Load KNdDBmaxr/minKgf.mCrCor3E904KAT218.82540.230000.22.051.463E905KAT2243250.230000.63.442.63E806KAT2304060.330001.65.154.073E907KAT2375080.3300037.135.863E809KAT2456090.430007.514.7613.183E911KAT25775120.530007.514.7613.183E812KAT26080130.530001215.5114.443E814KAT27095150.630002022.3821.573E815KAT275100150.630002526.425.673E818KAT29012018130004534.734.943E822KAT211015024115008043.5545.633E824KAT2120160241150012057.0257.753E826KAT2130175301150017081.5986.13E830KAT2150200301150020091.6102.673E832KAT2160220351.251500220115.66127.593E836KAT2180240351.51500250130.04146.473E838KAT2190250401.51500350139.96160.423E842KAT2210280451.51500400173.15210.913E844KAT2220300451.51500500181.72231Full ballsM14 Series Dimension dxDXH 25.07x33.896x6.095/6.35mmM17 Series Dimension dxDXH 30.3x41.722x 6.16/6.68mmM20 series Dimension dxDXH 35.56x49.073x7.24/8.13mmM25 series Dimension dxDXH 45.212X61.341X9.015/6.35mmM32 series Dimension dxDXH 58.928x79.756x11.81/8.64mmPls contact us for more dimensions~Packaging:Bearing+plastic bags+thin plastic foam+Carton box+wooden caseAnd different precision level ,pls contact us ~
