Product Overview

Designed for high-load and high-pressure environments, our radial cylindrical roller bearings (NU, NUP, NJ series) are critical components for hydraulic fracturing pumps. Engineered for durability, they ensure stable operation across diverse oilfield conditions.

Key Advantages

· Full Compatibility： Suitable for a wide range of equipment (100–5000 series pumps), including work over and fracturing units.

· Import Substitution： Precision manufacturing allows for direct replacement of imported brands, reducing costs and lead times.

· Custom Solutions： Capable of designing and manufacturing Non-standard bearings based on specific customer requirements.

                           

                           

Technical Highlights

· Optimized Internal Geometry

Utilizing advanced logarithmic crowning profiles on the roller and raceway surfaces, we minimize edge stress concentrations and equalize load distribution along the contact length. This significantly reduces the risk of premature spalling and enhances the bearing’s tolerance to misalignment, ensuring smooth operation even under severe working conditions.

· Superior Cage Design

Depending on the application severity, we offer reinforced pressed steel cages for maximum strength or precision-machined brass cages for superior high-speed and high-temperature stability. The optimized pocket clearance facilitates superior lubricant flow, effectively dissipating heat and preventing roller skewing during high-speed rotation.

Application Scope & Compatibility

Our bearings are rigorously tested and validated for seamless integration with a wide range of quintuplex and triplex fracturing pumps. We support the complete spectrum of industry-standard equipment:

· Conventional Series: 100, 300, 400, 500, 600 pumps.

· High-Power Series: 1600, 1800, 2000, 2500, 2800 pumps.

· Ultra-High-Power Series: 3000, 5000 pumps.
