Structure and Heat Treatment

1. The swivel of the rotary drilling rig is a metal connection structure, and the upper and lower joints, intermediates, etc. are made of forged alloy steel. After rough machining, strict heat treatment process shall be carried out before processing.

Main Application and Bearings

Bearing Brands

2. Bearing SKF and FAG are adopted for internal bearing.

Sealing Element System

3. The sealing element is NOK, the grease in the bearing inner cavity is not easy to leak, and the mud and sundries in the outer cavity are not easy to enter the bearing cavity, so as to ensure the normal operation of the bearing.

Frequently Asked Questions (FAQ)

QWhat is the primary function of the swivels on a rotary drilling rig?

The swivels are primarily used to lift the kelly bar and drilling tools during drilling operations.

QWhat materials are used for the main structural parts of the swivel?

The upper and lower joints, intermediate pieces, and elevator components are made from high-quality forged alloy steel, which undergoes rough machining followed by a strict heat treatment process.

QWhich bearing brands are used inside the swivels?

The internal bearings adopt premium SKF and FAG customized standards to ensure outstanding reliability and excellent performance under heavy load conditions.

QHow does the sealing system protect the internal bearings?

High-quality imported NOK sealing elements are used. They effectively prevent grease in the inner cavity from leaking, while stopping mud and external debris from entering the bearing cavity.

QWhat is the range of pulling force for these swivel models?

The pulling force depends on the specific model, ranging from 15-25 KN (for the JT20 model) up to 45-55 KN (for the JT50 model).
