This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Crossed Roller bearingachieves high rigidity and the precision can reach up to P4.P2,despite the minimum possible dimensions of the inner and outer rings,it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machinesRotation accuracy:The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the crossed roller bearingdoes not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted. In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.Usage characteristicsThe inner and outer rings, which are separable, are secured to crossed roller bearing body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other. Thus, it is easy to handle the rings when installing this type. Cross roller bearing typeRB type ( outer split type )RB series model for cross- Cylindrical roller bearings of the basic model , the inner and outer dimensions are the minimum possible , its structure is the outer ring is split type , the inner ring is the one designed for applications requiring high precision rotation of the inner parts .RE-type ( inner split type )RE series model is shaped by the XRB generated new style design , the main dimensions and XRB same type . Its structure is split inner ring is the type , the outer ring is the one designed for applications requiring high precision rotation of the outer parts .RU -type ( inner and outer one size )RU series models have been carried out since the mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .RBC -type ( outer split type )RBC Series models ( corresponding to the IKO's CRBC series ) whose structure is the outer ring is split type , the inner ring is integrated design , with cage full complement cylindrical roller bearings. Suitable for applications requiring high precision rotation of the inner parts .CRBH type ( inner , outer one size )CRBH series models , the outer ring is integrated structure for the outer ring and the inner ring rotates.RA type ( outer split , ultra-thin )RA Series models are the RB type , the outer ring thickness is reduced to the limit of the compact . For applications that require light weight, compact design of the site, such as robots and robotic rotating parts .SX type ( outer split type )SX Series Model Structure and RB series is similar to the structure of the outer ring is two divided by three snap ring connection , the inner one designed for applications that require high precision rotation of the inner place .XRU08 type ( inside and outside the ring one size )XSU08 series with RU series are similar, have been carried out outside the ring mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .RU series:RU42 RU66 RU85 RU124 RU148 RU178 RU124X RU148X RU178X RU124G RU148G RU178G RU228 RU297 RU445 RU228X RU297X RU445X RU228G RU297G RU445GSX series:SX011814 SX011818 SX011820 SX011824 SX011828 SX011832 SX011836 SX011840 SX011848 SX011860 SX011868 SX0118/500RA series:RA5008 RA6008 RA7008 RA8008 RA9008 RA10008 RA11008 RA12008 RA13008 RA14008 RA15008 RA16013 RA17013 RA18013 RA19013 RA20013RE series:RE2008 RE2508 RE3010 RE3510 RE4010 RE4510 RE5013 RE6013 RE7013 RE8016 RE9016 RE10016 RE10020 RE11012 RE11015 RE11020 RE12016 RE12025 RE13015 RE13025 RE14016 RE14025 RE15013 RE15025 RE15030 RE16025 RE17020 RE18025 RE19025 RE20025 RE20030 RE20035 RE22025 RE24025 RE25025 RE25030 RE25040 RE30025 RE30035 RE30040 RE35020 RE35025 RE40035 RE40040 RE45025 RE50025 RE50040 RE50050 RE60040 RE70045 RE80070 RE90070 RE1000110 RE1250110RB series:RB2008 RB2508 RB3010 RB3510 RB4010 RB4510 RB5013 RB6013 RB7013 RB8016 RB9016 RB10016 RB10020 RB11012 RB11015 RB11020 RB12016 RB12025 RB13015 RB13025 RB14016 RB14025 RB15013 RB15025 RB15030 RB16025 RB17020 RB18025 RB19025 RB20025 RB20030 RB20035 RB22025 RB24025 RB25025 RB25030 RB25040 RB30025 RB30035 RB30040 RB35020 RB40035 RB40040 RB45025 RB50025 RB50040 RB50050 RB60040 RB70045 RB80070 RB90070 RB1000110 RB1250110
