A bearing device includes two co-axially arranged radial spherical bearings and can be used for mounting a pivoting swing arm of a vehicle suspension to a vehicle frame. By using the two radial spherical bearings together the pivot attachment only has a single degree of freedom. The radial spherical bearings are positioned against shoulders in a sleeve of the swing arm and around a spacer sleeve. One or more lubricant grooves are formed at the sliding interface of the bearings. A bushing with a lip holds a lubricant seal for each bearing, and a dust cover protects each lubricant seal. A pivot pin rod is inserted through openings in the vehicle frame and through the two bearings and other components, and is tightened in place such as with a nut.
