Casing Bushings

Casing Bushings

Our company produces all kinds of bushings, including casing bushings, kelly bushings and so on. Casing bushings are manufactured with high-strength heat treated steel. They're specially designed to work with NOV rotary equipment and handling tools. With interchangeable insert bowls, these casing bushings can accommodate casing sizes from 16 inches up to 42 inches in diameter. There are three standard types for choice. Models CU and CUL are solid bushings, while the Model CB is a split bushing. These bushings are available for 17 1/2 in to 49 1/2 in rotary tables. In the operation, casing bushings are inserted directly into the rotary table to ensure that the casing runs perfectly with the center of the hole.

  • With the high-strength steel structure, casing bushings feature strong hardness and good durability.
  • Casing bushings are a preferred choice when to be used as part of a rotary drilling package, or as a replacement for existing bushings.
  • Casing bushings, kelly bushings and other bushings can all be offered in a wide variety of sizes to fit most rotary tables in the industry.
