A fluid conducting swivel joint of inexpensive construction having a rotatable sleeve member surrounded by a casing member and including a pair of spaced-apart preloaded thrust bearings for permitting relative coaxial rotation between the sleeve and casing members. The thrust bearings are mounted in the spaced-apart relationship on the sleeve member by a split collar retained thereon by a cup-shaped retainer. Fluid and dust seals are provided between the members for preventing leakage of the fluid and the ingress of dust or other debris into the bearings, respectively. Also, the swivel joint may be provided with a pair of radial bearings so that it can withstand extreme side loads. |
