Ruland Manufacturing coupling hubs are designed for connecting shafts for torque transmission applications. These are one of the components for three-piece design comprising 2, anodised aluminium hubs & a centre disk. These couplings operate with low bearing loads, thereby protecting sensitive system components like bearings and can accommodate high parallel misalignments. They have lightweight, 2024-T351 aluminium construction with black oxide finish for preventing abrasive fluids & particles from damaging the coupling hubs. Choose from a broad range of these coupling hubs, available in 7/8, 5/8, 3/4, 1/2 & 1 inch bore diameters.
