Self-aligning ball bearing product features
It is mainly subjected to radial loads and can withstand small axial loads. The axial displacement of the shaft (outer casing) is limited to the clearance limit, and has automatic self-aligning performance, allowing normal operation under the condition that the inner and outer sides are relatively inclined, and is suitable for the parts in which the support seat hole cannot strictly guarantee the coaxiality.
Self-aligning ball bearing structure
Self-aligning ball bearings with dust caps and seals are filled with the right amount of grease. They should not be heated or cleaned before installation. No lubrication is required during use. Adapt to operating temperature - 30 °C to + 120 °C. between. Main purpose of self-aligning ball bearings: Suitable for precision instruments, low noise motors, automobiles, motorcycles and general machinery, etc. It is the most widely used type of bearing in the machinery industry.

In terms of profit, the profit growth rate at the beginning of last year was close to 60%. However, due to the large increase in costs, the industry profit for the whole year fell, and the growth rate dropped to around 10%.
The bearing import and export again showed a surplus. It is understood that since the international financial crisis, the bearing import and export deficit in 2009 was 800 million US dollars. In 2010, the bearing import and export deficit was 500 million US dollars. Last year, the bearing import and export regained a surplus, with a surplus of 330 million US dollars.
The bearing industry surplus reappears. On the one hand, China's export bearing market and structure have been rationally adjusted. The export share of large bearings and medium and high-end bearings has increased. On the other hand, due to the establishment of multinational bearing group companies in China, the number of imported bearings has decreased.
