Features of Crossed Roller BearingsStructural features: Crossed roller bearings are cylindrical rollers arranged perpendicular to each other on the 900 V-groove rolling surface through spacers, so the crossed roller bearings can bear radial load, axial load and moment load, etc. Multi-directional load. The size of the inner and outer rings is miniaturized, and the ultra-thin form is even closer to the limit of small size, and has high rigidity, and the accuracy can reach P4 and P2 levels. Therefore, it is suitable for joints and rotating parts of industrial robots, rotating tables of machining centers, manipulator rotating parts, precision rotating tables, medical machines, calculators, IC manufacturing devices and other equipment.Rotation accuracy: the vertical arrangement of the rollers in the bearing is equipped with spacers, which prevents the inclination of the rollers and the mutual friction between the rollers, and reduces the rotating torque. In addition, compared with the previous use of steel plate cages, there will be no roller contact or lock-up phenomenon on one side. At the same time, because the inner ring or the outer ring is a two-part structure, the bearing gap can be adjusted, even if preload is applied, high-precision rotational movement can be obtained.Usage characteristics: The divided inner ring or outer ring is fixed with the cross roller ring after the rollers and spacers are installed to prevent separation from each other, so the operation is simple when installing the cross roller ring. The spacer retainer eliminates the friction between the rollers, prevents the rollers from sideways, and can obtain a stable rotation torque. Since the rollers are arranged in a cross, it can withstand loads in all directions with only one set of cross roller rings. Compared with the conventional model, the rigidity is increased by 3 to 4 times.RB Standard Crossed Roller BearingShaft diameterNominal modelMain dimensions mmInstallation sizemmBasic load rating (radial)weightCorresponding modelmm  Inner diameterOuter diameterwidth Roller pitch diameterShDynamic load       CStatic load    kN IKONSKdDBrmindpkNkg20RB2008203680.52723.530.53.233.10.04  25RB2508254180.53228.535.53.633.830.05 NRXT250830RB30103055100.641.537477.358.360.12CRB3010 35RB35103560100.646.54151.57.649.120.13  40RB40104065100.651.547.557.58.3310.60.16CRB4010NRXT401045RB45104570100.656.55161.58.6211.30.17  50RB50135080130.66457.47216.720.90.27CRB5013NRXT501360RB60136090130.67468821824.30.3CRB6013NRXT601370RB701370100130.684789219.427.70.35CRB7013NRXT701380RB801380110130.6948710120.5320.38 NRXT801380RB801680120160.6989111130.142.10.7CRB8016NRXT801690RB9016901301611089811831.445.30.75CRB9016NRXT901690RB90209014020111510712332491.27 NRXT9020100RB10016100140161119.310912931.748.60.83  100RB1002010015020112311313333.150.91.45CRB10020NRXT10020110RB11012110135120.6121.811712712.524.10.4  110RB11015110145150.6126.512213623.741.50.75  110RB1102011016020113312014334541.56CRB11020NRXT11020120RB12016120150160.6134.212714124.243.20.72  Shaft diameterNominal modelMain dimensions mmInstallation sizemmBasic load rating (radial)weightCorresponding modelmm  Inner diameterOuter diameterwidth Roller pitch diameterShDynamic load       CStatic load    kN IKONSKdDBrmindpkNkg120RB1202012017020 1451371522546.70.72 NRXT12020120RB12025120180251.5148.713316466.91002.62CRB12025NRXT12025130RB13015130160150.6144.51371522546.70.72  130RB13025130190251.515814317469.51072.82CRB13025NRXT13025140RB14016140175161154.814716225.950.11  140RB14025140200251.516815418574.81212.96CRB14025NRXT14025150RB15013150180130.61641571722753.50.68  150RB15025150210251.517816419476.81283.16CRB15025NRXT15025150RB15030150230301.51881732111001565.3CRB15030NRXT15030160RB16025160220251.5188.617320481.71353.14  170RB17020170220201.51911841982962.12.21  180RB18025180240251.5210195225841433.44  190RB19025190240251211.920222241.782.92.99  200RB2002520026025223021524584.21574CRB20025 200RB200302002803022402212581142006.7CRB20030NRXT20030200RB20035200295352247.72252701512529.6CRB20035 220RB22025220280252250.123526592.31714.1  240RB24025240300252.526925628168.31454.5  250RB25025250310252.5277.526529069.31505CRB25025NRXT25025250RB25030250330302.5287.52693061262448.1CRB25030NRXT25030250RB25040250355402.5300.727532619534814.8CRB25040 260RB26035260330252.5293280305623068.7  300RB30025300360252.532831534076.31785.9CRB30025NRXT30025300RB30035300395352.534532236818336713.4CRB30035NRXT30035300RB30040300405402.5351.632637721240917.2CRB30040NRXT30040350RB35020350400202.5373.436338354.11433.9  400RB40035400480352.5440.342245915637014.5CRB40035NRXT40035400RB40040400510402.5453.442847924153123.5CRB40040NRXT40040400RB4007040058070 48143053247081172.4  450RB4502545050025147446448461.71826.6  500RB50025500550251524.251453465.52017.3  500RB50040500600402.5548.852657223960726CRB50040NRXT50040500RB50050500625502.5561.653658726765341.7CRB50050NRXT50050600RB6004060070040365062767326472129CRB60040NRXT60040700RB70045700815
