Product Description Detailed parameters-RU297 Bearing Drawing-RU297 RU297G RU297X XRU21040RU297 bearing is a precision cross roller bearing with cylindrical rollers as rolling elements. There are three types of mounting structures:RU297; both inner and outer rings are smooth holes, and the countersunk holes are in the same direction;RU297G; both inner and outer rings are smooth holes, and the countersunk holes are in opposite directions;RU297X, the outer ring is smooth and the inner ring is threaded;RU297GUUCCOP4 is used for bearings with industrial mechanical arms,High Precision Bearing. What kind of bearing is model RU297 bearing?The cross roller bearing is suitable for precise applications requiring multi-directional bearing, such as robot arm, precision turntable, etc.The bearing itself is designed with negative clearance, so the bearing is rigid enough to withstand large loads and has high precision (basically, it beats between 0.001mm and 0.01mm, and the bearing precision is above P5).How to install this series of bearings?The selection of cross roller bearing is mainly to consider the mounting mode and size of the bearing, which can be divided into the following two types:1. The cross roller bearing without installation hole has a thinner wall thickness, which is suitable for small installation space. High Precision Bearing needs to be pressed on the equipment with flange plate. The specific difference of RB/RE/CRBH/SX/RA type is as follows2. The inner and outer rings of the cross roller bearing with mounting holes are designed with mounting holes for convenient installation and use. They are widely used in robots and turntables.RU series Bearings models-RU297 bearingRU28;XRU1008 RU42;XRU2012 RU52;XRU2512; RU66;XRU3515; RU85;XRU5515; RU124;XRU8022;RU124G; RU124X; RU148;XRU9025; RU148G; RU148X RU178;XRU11528;RU178G; RU178X; RU228;XRU16035; RU228G; RU228X; RU297;XRU21040; RU297G;RU297X; RU445;XRU35045; RU445G; RU445X; RU297 Assembly drawing RU297G Assembly drawing RU297X Assembly drawing Bearing typeRU297Inner diameter (mm)-210outer diameter(mm)-380thickness(mm)-40weight(Kg)-22.3The material-GCR15/GCR15SiMnPrecision grade-P5/P4/P2Lubrication type-greaseRotating way-The inner and outer circles rotateLoading direction-Axial and radial multidirectional loadingBearing structure-The inner and outer circles are onetypeMain dimensionsInstallation dimensionsBasic rated load (radial)()weightInner diameterd(mm)outer diameterD(mm)Roller garden diameterdp (mm)thicknessB(mm)The oil holeφchamferingr(min)dsDhC kNCo kNKgRU297GUUCC0210380297403.12.52612951562816.8 ,RUProduct features90V,,.,,,P2.,,,,,IC.RU297 bearing are two columns of cylindrical rollers arranged vertically across each other through nylon isolation blocks on the 90-degree v-shaped raceway, so cross roller bearing can withstand radial load, axial load and torque load.The dimensions of the inner and outer rings are miniaturized, the extremely thin form is close to the limit of the small size, and has high rigidity, the cross roller bearing precision can reach P2 level.It is suitable for joint rotating part of industrial robot, rotating table of machining center, precise rotating table, medical machine, calculator, IC manufacturing device and so on.Product description of the same series as model RU178RU(),.,,,..RU type (inner and outer ring type) this series of models have been processed with mounting holes, so there is no need to fix flanges and supports. In addition, because of the integrated inner and outer ring structure with the seat, the installation has little effect on the performance, so stable rotation precision and torque can be obtained. Can be used for outer ring and inner ring rotation.More modelsRU66(CRBF3515),RU85(CRBF5515),RU124G(CRBF8022),RU148G,RU178G,RU228,RU297,RU445,RU228X,RU297X,RU445X,RU228G,RU297G,RU445GApplicable occasions-----Nc machine tool - nc rotary table - industrial robot arm - precision speed reducer - detection equipment - precision medical equipmentMore bearing models are welcome to contact us.
