The oil and gas industry is striving to push the limits of what is technically feasible. Deeper wells, harsher environments and more demanding drilling methods are placing ever higher demands on equipment, requiring bigger, stronger and more powerful solutions, especially However, when unplanned downtime may cost the factory 1 million yuan per day, more and more people concerned begin to pay attention to the reliability and stability of machinery.
In order to meet the increasing needs of major customers, SKF has now developed a new generation of tapered roller thrust bearings, SKF Explorer tapered roller bearings have higher load capacity and up to 300% bearing life, can be used for the next generation of larger, Stronger drilling, while also helping to improve the reliability of existing products.
In order to maximize the bearing's effective load-carrying capacity and improve resistance to shocks and peak loads, SKF has optimized the length and diameter of the rollers, as well as the profiles of the rollers and the raceways, with careful contact between the rollers and the raceway profiles. The perfect interplay minimizes the risk of edge tension, while the smooth transition of the raceway edges helps avoid sharp edges and stress peaks.
Strictly narrowed manufacturing tolerances minimize diameter deviations between rollers, ensuring a more even load distribution, and the surface quality of bearing components has also been improved, with optimized bearing outer surfaces and reduced roughness to avoid stress peaks , and maintain an effective lubricating film during start-up and operation, the shaft and housing discs are constructed using the most advanced finite element method, and the optimized undercut at the raceway flange transition reduces stress peaks and improves resistance under high loads Fatigue or fracture resistance, while the overall tolerance is narrowed to reduce friction at the roller ends, and a special case hardening process further reduces crack growth and damage caused by impact loads.
SKF Explorer tapered roller bearings have new, optimized brass cages or pin cages, especially suitable for extreme applications, and both cages are available in symmetrical or asymmetrical versions to meet the requirements of various applications.
