New self-lubricating ntn double row tandem ball roller bearing applications

"The ball roller bearings," the invention is based on a genius idea, which is new in the rolling body and a combination of new assembly methods. Not bear the load of all the traditional roll "ball" of the ball have all been removed. This means that 15% of the diameter of the ball on both sides were removed. The result is the so-called roller ball, a flat on both sides of the ball, the ball really narrow than 30%. This significantly saves valuable space.
In addition, the shape of special "slim" roller ball and special development of assembly methods, can increase the number of rolling to about 90% of filling space. In the same space, more ball can achieve higher load, in order to achieve a longer product life. It also provides a new reduced product size and assembly opportunities. Double-cage design can achieve the best of two independent roller adjustment, and with perfectly matched. This ensures that the minimum size and lower friction bearings for maximum load support.
SF-2 boundary lubricated bearings plus: acid poly A with formaldehyde, with high wear resistance, bearing surface arrangement of the law must be fitted with oil storage pits filled with grease, especially for low speed under high load rotational motion, rolling motion, and often borne, the opening and closing the difficult parts of the formation of lubrication in boundary lubrication conditions, long-term use without refueling and maintenance, where the fuel bearing life can be extended to more , currently applicable to metallurgical machinery, mining machinery, irrigation machinery, automobile parts, construction machinery, agricultural machinery.
Oil-free self-lubricating bearings: The product is steel plate as the substrate, the middle layer of sintered bronze spherical powder, rolling surface of PTFE [ptfe] and a mixture made of lead. It has a low coefficient of friction, wear resistant. No oil from the lubrication and long service life, use it to reduce costs, reduce noise, to prevent the sticky, slippery. It is widely used in the sliding parts of machinery such as printing presses, textile machines, hydraulic truck, tobacco machine, pharmaceutical machinery, fitness equipment, micro-motors, automobiles, and motorcycles.
Metal matrix solid self-lubricating bearings mosaic: a metal bearing both the characteristics and features of the new self-lubricating bearings lubricated bearings, and loaded by the metal matrix, a special formulation of solid lubricant material as a lubricant. It has a high carrying capacity, impact resistance, high temperature, self-lubricating ability and so on.
The traditional oil bearings: The Noise Due to the low, the advantages of self-lubricating, oil-bearing has become the new darling of the computer CPU fan bearings, market demand; In addition, as people become increasingly demanding on the noise, oil-bearing Application of the daily household appliances are also being expanded.
