API 7K Casing Bushing Square Drive Insert Bowl Reduces Friction

API 7K Casing Bushing Insert Bowls for Oil Drilling Rig

This bushing is an essential tool for petroleum drilling. It mates with the rotary table master bushing to drive the kelly. Fitted with four rollers, it reduces friction against the kelly during rotation and extends service life of the kelly. For square and hexagon kellys of different sizes, matching can be achieved by replacing the rollers. It is compatible with various types of rotary tables and is available in two‑rotation configurations: square‑drive type and pin‑shaft drive type. It is designed and manufactured in accordance with API Spec 7K Specification for Drilling Equipment.
