Product Description

API 7K Standard Roller Kelly Bushing Forged Drilling Equipment for Well Drilling

HDS Kelly Roller Bushing

This core is an essential tool for oil drilling. It matches the square tile of the rotary table and drives the square drill rod. The product reduces the friction with the square drill rod through the rotation of four rollers and prolongs its life. For square and hexagonal square drill rods of different specifications, they can be matched with them by replacing rollers and connected with various rotary tables. There are two forms of four-way rotation and pin rotation. Designed and manufactured according to API Spec 7K "Drilling Equipment Specification".
