Bicycle Headset is a small but important part of bicycle direction system. It is a bearing assemble at head tube that connects the handlebar to the top tube of the fork, allowing it to be rotated for steering and balance purposes. Because of the protruding shape of the bearing base, so it also called a Bicycle Bowl Set.
Our Bicycle Head Set made of aluminum alloy so it has a good strength and nice regular shape, the surface is glossy and has bright color due to the good baking paint. Some shop also sells the steel Bike Headset to use on lower-end public bicycles or very cheap bikes, but will rust if gets wet or keep in humid environment.

Oil-free was founded in 1980, the former Ministry of Machinery Industry formed the last subordinate industry focal point Institute. In fact, after the disintegration of the Soviet Union, there was only one China-based oil-free agency in the world.
Oil-free establishment process is planned economy. In the late 1970s, the Ministry of Machinery Industry organized a technical tackle for oil pump nozzles in Wuxi, thus mobilizing 200 relevant technical experts to Wuxi. One reason to choose Wuxi is that there are key enterprises in the industry without oil plants. The traditional so-called "one plant, one" model.
Weifu research and development partners
No oil just normal operation, the state began the first science and technology system reform. In order to bring scientific research institutions to market, an important part of the reform started from 1986 onwards, reducing the funds originally allocated by the Ministry of Finance by 20% each year until it was reduced to 20% of the original figure in 1990. In 1990, the corresponding funding from non-oil financed by the government was reduced to 460,000 yuan and maintained so far. All other requirements are funded by the Institute.
As the only professional research institute, Oil-Free has been a partner of Weifu (Oil-Free Plant) in R & D for a long time since its inception. At the beginning of the establishment, the Ministry of Machinery Industry appointed Zhu Wenbin, director of the oil-free factory, as its first director. It was precisely this leadership Zhu Wenbin oil-free plant to achieve from the "supporting for agricultural machinery" to "supporting the internal combustion engine," a key turning point, which laid the Weifu in the domestic industry-leading position. Later, both the imitation, the introduction of technology, or the joint ministries in charge of research and national scientific research projects, the two sides work closely together. There are also crossings. At present, the chief engineer of Weifu has been mobilized from oil-free operations. However, the former leader of Weifu also retired to no oil office. At that time, oil-free research results (technical information and drawings) were provided to Weifu at no cost.
In the mid-1990s, the state started the second scientific and technological structural reform with the transformation of research institutes as its main content. Probably trained by the experience of "a weaner at birth", Oilfree started looking for a way out early and has been in contact with FAW since 1993. In January 1995, No Oil Co. formally joined the FAW Group (there is a gap in the field of diesel engines) and became one of the earliest restructurings in the research institutes. Although "Wuxi No.1 Fuel Cell Research Institute" has been labeled "China FAW Group Corporation" since then, it still retains the name of "Wuxi Institute of Oil Pumps and Mouthpieces of the Ministry of Machinery Industry" and its function of serving the industry.
Strategic shift to focus on fuel injection system
In the process, oil-free made an important decision to move toward a comprehensive engine research institute in a research direction from a narrow-based research institute. In the past system, engaged in the research of the pump nozzle agencies do not allow engine research; engaged in vehicle research can only be devoted to vehicle chassis technology, and can not engage in engine research. In general, foreign engine manufacturers usually have a strong fuel system development capabilities and vehicle matching capabilities, OEMs usually have a very strong engine R & D strength.
Since 1996, the entire R & D system has been adjusted to be oil-free. First of all, the R & D area will be broadened. From the original research on oil pump nozzles, it will be expanded to other engine technologies such as combustion system, intake and exhaust system, valve train, lubrication system, supercharging technology, simulation calculation and cooling system. Secondly, the depth of research and development is divided into three levels: near, middle and far. Recent research and development, mainly to solve the technical problems encountered in the actual production of enterprises (first to meet FAW Group's corporate R & D tasks); mid-term mainly for major technological research enterprises and new products, new technology development and research; far Mainly follow the international forefront of technology, maintain the world level of synchronization of ultra-high-level technical research.
It is because of this strategic shift that oil-free research activities have come out of the established framework to focus on the cutting-edge technology of injection systems from the standpoint of improving engine performance. At the same time, such a market orientation has enabled NOF to continue its R & D activities from the needs of technological progress in the industry and maintained a tradition of taking responsibility for the technological progress of the industry.
Open research and development breakthrough Europe II standards
From its founding date, Oil-Free is not a closed-door research organization. In order to improve their own level and unified thinking, at that time no oil organized a British CAV technical experts to come to China for technical exchanges, but also invited the former Soviet Union's oil nozzle Institute visit. These old experts have their own basis, foreign experts and lectures is "a little pass."
After the initial construction work, oil-free research and development work quickly carried out. In the era of mechanical pumps, oil-free has been able to produce their own designs based on the study of foreign products. For example, the BQ pump was designed in 1983 and started production in 1986-87. Later BX pump is the largest production of small pump products on the market.
After the country began to gradually implement the emission standards, many domestic enterprises can not meet the emission requirements of products, resulting in many OEMs and engine plants on national laws and regulations have a resistance. With its technology accumulation in engines and pump nozzles, Oil-Free has been involved in many technological transformation projects and can even help companies improve their engines to ultimately help companies meet emission standards. Oil-free at the time of the technical programs in China is the first to meet the European I Europe II demand. Chairman of Shandong Longkou Pump Nozzle Factory believes that the Euro II system developed by No Oil rescues China's oil pump nozzle industry.
Until the late 1990s, oil-free still in the field of mechanical fuel injection system for the domestic industry to provide new products, such as to meet the European II standard PM pump was approved in 1999, the development of mature and patent in 2002, and Shandong Longkou Long Pump Pumps Factory, ASIMCO (a manufacturing company controlled by an investment company in the United States) and Beijing Pump Factory. In fact, many related domestic enterprises have benefited directly or indirectly from the technological progress and accumulation of oil-free houses.
Oil-free: to save China's oil pump nozzle industry
Chairman of Shandong Longkou Pump Nozzle Factory believes that the Euro II system developed by No Oil has saved the Chinese pump industry. There is a common understanding in the Chinese machinery industry that the engine industry has dragged the hind legs of the automobile industry while the pump and oil nozzle industry Dragging the hind legs of the engine industry.
