RU Series Cross Roller Bearing

RU Series Cross Roller Bearings Are Designed As An Integral Structure For Inner And Outer Rings. Because The Inner And Outer Rings Have Machined Installation Holes, There Is No Need To Fix Flanges And Support Supports, Which Shortens The Axial Space Distance And Optimizes The Use Mechanism. In Addition, Because Of The Integrated Inner And Outer Rings Structure With Seat, Installation Has Little Effect On Performance, So Stable Rotation Accuracy And Torque Can Be Obtained, And The Outer Rings Can Be Used. It Is Suitable For Both Inner Ring Rotating Mechanism And Is Widely Used In Robot Waist Joints, Welding Multi-Station Rotary Table, Communication Radar, Precision Measuring Instruments And So On. img06614 img15586 Designation Dimensions（Mm） Basic Load Ratings（KN） Weight D D B D2 D1 N1 N2 D1 D11 T1 D2 D21 T2 Rsmin Cr Cor Kg RU42 20 70 12 57 28 6 6 3.4 6.5 3.3 M3 —— —— 0.6 7.35 8.35 0.29 RU66 35 95 15 83 45 8 8 4.5 8 4.4 M4 —— —— 0.6 17.5 22.3 0.62 RU85 55 120 15 105 65 8 8 5.5 9.5 5.4 M5 —— —— 0.6 20.3 29.5 1 RU124(G) 80 165 22 148 97 10 10 5.5 9.5 5.4 5.5 9.5 5.4 1 33.1 50.9 2.6 RU124X 80 165 22 148 97 10 10 5.5 9.5 5.4 M5 —— —— 1 33.1 50.9 2.6 RU148(G) 90 210 25 187 112 12 12 9 14 8.6 9 14 8.6 1.5 49.1 76.8 4.9 RU148X 90 210 25 187 112 12 12 9 14 8.6 M8 —— —— 1.5 49.1 76.8 4.9 RU178(G) 115 240 28 217 139 12 12 9 14 8.6 9 14 8.6 1.5 80.3 135 6.8 RUI78X 115 240 28 217 139 12 12 9 18 8.6 M8 —— —— 1.5 80.3 135 6.8 RU228(G) 160 295 35 270 184 12 12 11 18 11 11 18 11 2 104 173 11.4 RU228X 160 295 35 270 184 12 12 11 18 11 M10 —— —— 2 10.1 173 11 4
