Saudi Arabia, the world’s largest oil exporter, who recently announced a significant reduction in official oil prices and increased production. International oil prices on the 9th hit the most significant one-day drop since the 1991 Gulf War. Against the backdrop of weak global crude oil market demand, Saudi Arabia’s increase in output and price cuts will exacerbate the imbalance between supply and demand in the market. Where will the major oil producers fight to bring international oil prices?
It is understood that to balance market supply and demand. It stabilizes oil prices since the OPEC and non-OPEC oil-producing countries reached agreement on production reduction at the end of November 2016, they have maintained cooperation on production reduction.
Russia is the non-OPEC oil-producing country that has cut the most. But this time, Russia is unwilling to sacrifice market share to support oil prices. According to RIA Novosti News Agency, a spokesman for Rosneft, Russia’s largest oil producer, said that the output reduction agreement will not benefit Russia and will only allow the US shale oil to occupy more market share.
Bearings are an essential part of smelting petroleum equipment. Rotary disk bearings can be divided into four-point contact ball rotating disk bearings, crossed cylindrical (tapered) roller rotary disk bearings. Double-row four-point ball rotary disk bearings, double-row different diameter balls according to various structural types. Type rotary table bearings, ball-roller combinations, and three-row cylindrical roller combination rotary table bearings, etc .; the above types of bearings are divided into toothless, external gear, or Internal gear and other structures.
Turntable bearings can meet the needs of working hosts under various load conditions according to different structural points. Among them, the four-point contact ball turntable bearing has a higher dynamic load capacity. The crossed cylindrical roller turntable bearing has a higher static load capacity, and the three-row cylindrical roller combined turntable bearing leads to an increase in the bearing capacity to the height direction of the bearings. Separate raceways and roller sets take various loads, so under the same stress conditions, the diameter of its raceways is significantly reduced, which has the point of making the host more compact, and it is a high-capacity turntable bearing.
