good impact resistance

Design features XRT Series has two tapered roller at 90 ° to the surface of the V-cutter vertical cross through the spacer retainer arrangement can bear radial load, axial load and other loads in any direction. Raceways and rollers on the line contact structure provides maximum rotational accuracy, high stability and greater tilt stiffness. Preload adjustable design extends bearing life, the maximum extent possible to increase the rigidity and provides a minimal beat. Nylon spacer lower inertia, running less torque. Components using surface-hardened steel or Tapered bearing steel electroslag remelting, good impact resistance

Low statistics show that in 2011 the national bearing industry to complete the main business income of 142 billion yuan, an increase of 12.7%, bearing production completed 18 billion units, an increase of 20%; annual export sleeve bearing 4900000000, earning $ 4.5 billion, respectively. over the previous year increased by 18.2% and 36.6%, total imports of 1.88 billion sets of bearings, use of foreign exchange $ 4.17 billion, respectively, over the same period last year increased by 4.6% and 9.4%, trade surplus continued to increase, reaching $ 330 million.
Association officials think the central axis in the international political and economic situation is complicated in the context of the bearing industry has experienced rapid growth after 2010, in 2011 there have been high to low running posture, the whole industry into a structural adjustment and rational regression phase.
2011 bearing industry still maintained a certain growth throughout the year. In early 2011, the whole industry the main business revenue grew more than 26 percent in the second half, an increase constantly down, but in 2011 the industry still maintained a growth rate above 12%, while export revenue bearing smaller decline, industry Bearing Import & Export surplus of more than 300 million U.S. dollars.
From the bearing sales terms, the number of monthly basic balance between total sales, but bearing inventory turnover of view, although the growth rate fluctuations, but the overall upward trend. Inventory turnover than the beginning of the end of 2011 increased by 40%.
From the profit point of view, the beginning of 2011 nearly 60% profit growth, but due to a larger increase in costs, the final full-year decline in industry profits, growth rate down to around 10%.
Bearing import and export again to show a surplus. It is understood that since the international financial crisis, the 2009 deficit of $ 800 million export bearing, 2010 bearing import and export trade deficit $ 500 million, in 2011 to reproduce bearing import and export surplus, the surplus amounted to $ 330 million.
The person in charge, the bearings industry surplus reproduction, one is China's export market and the structure bearing a reasonable adjustment, high-end bearings and bearing large share of exports increased, partly because multinational Bearing Group companies in China have set up factories , bearings decreases.
