Luoyang MONTON Bearing Completes Technical Breakthrough in Heavy-Duty Frac Pump Bearings

Fracturing pump bearings are the core components at the power end of oil and gas extraction fracturing pumps. They ensure the stable operation of fracturing pumps under harsh working conditions of high pressure and high impact, and serve as the key supporting bearing parts for fracturing pumps. Installed at the power end of fracturing pumps, these bearings can withstand combined radial and axial loads under high-pressure working conditions, limit the axial displacement of the shaft system, and reduce the impact of components caused by pressure fluctuations.

The fracturing pump bearings produced by Monton mainly include cylindrical roller bearings, spherical roller bearings and non-standard crankshaft bearings. For some heavy-load scenarios, the full-ball design structure is adopted. They are widely supporting various oil and gas extraction main equipment such as fracturing pumps, mud pumps and parallel transmission devices, covering multiple oil and gas extraction scenarios on land and offshore. Our fracturing pump bearings feature low friction, high load-bearing capacity, high temperature resistance, water and dust proof performance, and impact resistance.

In the working environment of fracturing pumps, bearings need to withstand the erosion of highly abrasive mud, so the wear and corrosion resistance technology becomes the key. By optimizing the bearing design structure, MONTON Bearing effectively improves the wear resistance and corrosion resistance of bearings, which can extend the bearing service life by more than 50%, and significantly reduce the equipment maintenance cost and downtime.

With the domestic oil and gas extraction equipment developing towards high power and the continuous technological iteration of equipment, fracturing pumps, as the core main equipment of fracturing operations, have put forward higher requirements for their supporting bearings in terms of performance stability, service life and wear resistance. This has become a key link in the upgrading of the oil and gas equipment industrial chain. According to the latest industry survey data, the localization supporting rate of domestic fracturing pump bearings has exceeded 82% in 2026. The continuous fault-free operation time of products from leading manufacturers on 8000-type and above high-horsepower fracturing pumps has increased by 47% compared with 2023, gradually breaking the long-term monopoly of overseas brands in the field of high-end heavy-duty products.

The localization breakthrough of fracturing pump bearings not only directly reduces the manufacturing cost of oil and gas equipment, but more importantly, solves the potential "stuck neck" risk of core components under extreme working conditions, providing key support for the continuous and efficient operation of domestic oil and gas fields.

In the next step, as domestic oil and gas extraction extends to deep and ultra-deep scenarios and the large-scale popularization of all-electric drive fracturing equipment, fracturing pump bearings will be iterated towards higher rotating speed, stronger corrosion resistance and longer maintenance-free cycle. Domestic manufacturing enterprises will further control the supply interruption risk within an acceptable range by establishing a strategic reserve library and building a dual-track mechanism for domestic alternative suppliers, so as to promote the whole-process independent controllability of core components of oil and gas equipment.
