We have more experience
in swivels than Elvis.

Before a swivel is purchased, careful consideration should be given to
size, capacity, requirements and speed at which it will be rotated.
Other factors to be considered are overloading and shock loads. The
structural parts of all King power swivels, except Type J, are made of
high-grade alloy steels. These parts are heat-treated to improve their
qualities. Type J housings are made of aluminum alloy or nickel iron. All
parts are subject to stresses and have safety factors that provide very
wide margins beyond the safe limits indicated in the rating tables.

Selecting the perfect swivel

Any swivel is frequently subjected to overloads and shock loads unless a much larger swivel is used
than is normally required. Common causes of overloads: using too long and too heavy strings of drill
pipe and pulling on stuck pipe. Shock loads result when the pipe is lifted suddenly. Severe
shock loads are imposed when spudding gumbo off the bit. The worst shocks are delivered by
rotary jars when used for loosening stuck drill pipe. Before deciding on the type and size of
swivel to purchase, consideration should be given to overloads, shock loads and bearings.


When referring to the load capacity tables, it is best to select the next larger swivel than is indicated
in the tabulation. This will provide some insurance against damage resulting from overloads, shock
loads and increases in speed of rotation. Much too frequently, a swivel is purchased to drill certain
depths. The operator may try to drill deeper than anticipated. The swivel is overloaded as a result. It
is false economy of the worst sort to use a swivel that is too small for the job. Excessive cost of
upkeep, plus shutdown time of the rig, will soon amount to the added cost of a larger swivel.

We swear by our swivels.

At King Oil Tools, our team of seasoned professionals has the
experience and deep expertise to provide product-specific
inventory, logistics, and troubleshooting solutions.


Like any other piece of equipment, power swivels should be kept in
good repair. It is our longstanding policy to give first attention to
repair orders, and repair replacement parts are invariably,
shipped out the same day an order is received. When a King
swivel needs repairs, other than packing, it should be returned to
us as soon as possible. We can usually repair it more economically
than anyone else because we are able to reclaim many expensive
parts that would otherwise be discarded. The greatest advantage
in returning your King swivel to us for repair is the fact that when
it is a factory job, the owner may feel assured that the various
parts fit correctly and that adjustments are properly made.
