A hose reel bearing arrangement supports a rotatable swivel shaft on a stationary hose reel frame. The bearing arrangement comprises a stationary bearing race, a rotating bearing race and a bearing. The stationary bearing race is anchored to the stationary hose reel frame, and has a stationary arcuate land for bearing an axial load, a stationary cylindrical land for bearing a radial load, and a stationary frustoconical intervening portion. The rotating bearing race is anchored to the rotatable swivel shaft, and has a rotating arcuate land for bearing the axial load, a rotating cylindrical land for bearing the radial load, and a rotating frustoconical intervening portion. The bearing is bracketed axially by the stationary arcuate land and the rotating arcuate land, and radially by the stationary cylindrical land and the rotating cylindrical land.
