The petroleum drilling TC bearing is also known as hard alloy bearing or radial hard alloy bearing. The TC bearing is made by integrating the core material with tungsten carbide powder and hard alloy through high-temperature sintering in a furnace, and then processed by mechanical means. It is a key component of petroleum drilling machinery. The TC bearing is one of the important accessories in the screw power drilling tools used in petroleum exploration drilling. It mainly withstands the radial loads generated during the operation of the transmission shaft of the power drilling tools. Its quality and performance directly affect the lifespan of the drilling tools as a whole. The TC bearing is located in its transmission part and is a key component affecting the lifespan of the screw drilling tools.
■ Application fields
Oil drilling, screw drilling tools.
■ Operating conditions of TC bearings
High pressure, corrosion, wear.
■ Characteristics of TC bearings
Malleability: The surface weld layer alloy block has high hardness and can resist wear by particle media.
Corrosion resistance: Made of nickel-based alloy, with excellent corrosion resistance.
Long service life: Different weld layer formulations are selected for different harsh operating conditions to enhance service life.
■ Solution
The TC bearings are fabricated using PTA and vacuum fusion infiltration technology, ensuring their wear resistance and service life under various operating conditions.
