Kelly bushing is that elevated device positioned right on top of the rotary table and used to transmit torque from the rotary table to the kelly. The kelly bushing is designed to be the connection between the rotary table and the kelly. The kelly is a 4 or 6 sided steel pipe.

The purpose of the rotary table is to generate the rotary action (torque) and power necessary to rotate the drillstring and drill a well. The torque generated by the rotary table is useless if it is not transferred to the kelly (the drillstring is connected to the kelly).

Hence, through the kelly bushing the torque generated at the rotary table is transferred to the kelly. To achieve this connection, the inside profile of the kelly bushing matches the outer profile of the kelly so that the kelly fits or “sits” comfortably in the kelly bushing.

There are various designs for the kelly bushing including the split type, the pin-drive type and the square-drive type. Each of these designs has different ways in which they are connected and disconnected from the rotary table.

The internal diameter of the kelly bushing can be cut into the shape of a square (4-sided) or a hexagon (6-sided) depending on the outer shape of the kelly that will be used. The internals of a Kelly bushing is designed to resemble the outer shape of a Kelly just like the insides of a key lock is cut to exactly match the outer shape of the key.

The kelly bushing is not designed to hold tightly onto the Kelly; the kelly is still permitted to move up and down through the kelly bushing. This requirement is a must since drilling cannot progress if the kelly remains on a fixed spot. As the well is drilled deeper, the kelly also moves downward through the Kelly bushing.

The kelly bushing is sometimes used as a reference point from which depth measurements can be taken. All depths must be recorded with respect to a reference point; the kelly bushing (KB) is one of the depth references used in the oil and gas industry.

The top of the kelly bushing is normally used as the depth reference.For example, 7500ft KB means 7500ft below the kelly bushing or 7500ft measured from the top of the kelly bushing down to that point in the well.

In some other cases, depths could be recorded as 7500ft MDBKB meaning 7500ft measured depth below the kelly bushing. This is mostly used when the measured depth is different from the true vertical depth of the well, common with deviated and horizontal wells.

An adapter that serves to connect the rotary table to the kelly. The kelly bushing has an inside diameter profile that matches that of the kelly, usually square or hexagonal. It is connected to the rotary table by four large steel pins that fit into mating holes in the rotary table. The rotary motion from the rotary table is transmitted to the bushing through the pins, and then to the kelly itself through the square or hexagonal flat surfaces between the kelly and the kelly bushing. The kelly then turns the entire drillstring because it is screwed into the top of the drillstring itself. Depth measurements are commonly referenced to the KB, such as 8327 ft KB, meaning 8327 feet below the kelly bushing.

Please send us your inquiry with detail item description or with Model number. If there is no packing demand we take it as our regular exported standard packing. We will offer you an order form for filling. We will recommend you the most suitable model according to information you offered.

Roller Kelly Bushings can be classed as two types based on different ways of drive, square drive and pin drive. Also they can be classed as three types based on different style, heavy, medium and light-duty. They are used for 17.1/2 to 49.1/2inch rotary tables. They are designed and manufactured according to API Spec 7K.

Rotary kelly bushing - an adapter that serves to connect the rotary table to the Kelly, which turns the entire drillstring. Depth measurements are commonly referenced to the RKB, such as 10,000 ft. RKB, meaning 10,000 feet below the rotary kelly bushing.

General Petroleum Oil Tools Pin Drive and Square Drive Kelly Bushings are designed for rugged high torque and high speed drilling operations. A variety of types and sizes are available.

Pin drive bushingsPin drive bushings consist of lower body half, upper body half, roller and roller pin, etc. when the bushing is installed to square kelly or hex kelly, the square part of the lower body half can be fitted in the square of the master bushing. When operating, the rotary table drives master bushing and master bushing drives roller kelly bushings ...

Square drive bushingSquare drive bushing is also referred to as roller bushing or roller kelly bushing. This roller bushing is an essential drilling tool. Square drive bushing is used for 17 1/2-49 1/2 inch rotary tables. It"s designed and manufactured according to API Spec 7K. The roller kelly bushing works with master bushing to drive dril...

This roller kelly bushing is an essential drilling tool. The bushings are designed with two drive methods, i.e. square rolling and pin shaft rolling. And according to type, there are heavy, medium and light-duty kelly bushings. The roller kelly bushing can be equipped with turntable slips to drive the square or hexagon kelly bar.

Kelly bushings consist of top cover, base, axis, needle bearing, sealing body, roller, binding bolt, and refuel cup. The needle bearing within the roller is installed on axis whose both ends are compact between top cover and base. The refuel cup lying on axis end injects grease into needle bearing at regular intervals. In order to prevent the sealing body from penetrating and protect the needle bearing, the inner-outer O type circle must be installed on the both ends of the roller. Fasten pin lying on the top of sealing body prevents it from rotating, and inlays are inside seam allowance of up base.

To produce kelly bushings and other drilling tools, the company possesses strong technical force, excellent production equipments and complete test facilities. And we"re focusing on new products making and market expanding all the time. Now Jiangsu Kayson Petrol- Machinery Co., Ltd becomes a first-level supply member of Chinese Petroleum & Natural Gas Consortium. At the same time, it"s also the member of China Petrochemical Material Resources Market.

These 2 important is very important for drilling rig owner. After years when your machine needs maintenance you wont need our factory send you parts for maintenance.
