Connecting rod bearings provide rotating motion of the crank pin within the connecting rod. The most common symptoms of a connecting rod bearing failure is a broken connecting rod piercing the crankcase; a problem that can be caused by bad rod bearings. A failed rod bearing will end up producing a metallic knocking or rumbling noise from the engine, especially during cold starts.

Polyurethane elastomers are widely used in China and need to accelerate development
The application of polyurethane elastomer (TPU) is more and more extensive, the number of product varieties is increasing, the scale of production is expanding, and the diversified development momentum is playing an important role in the national economy and social production and life. China's demand for polyurethane elastomers has also increased year by year, but some key raw materials still rely on imports, which is not conducive to the further development of the polyurethane industry. In the future, we will accelerate the localization of key raw materials and produce raw materials with excellent performance and low prices.
Polyurethane elastomers are typical multi-block copolymers with excellent properties such as high elasticity, high hardness, high strength, good wear resistance, low temperature resistance, and resistance to flexing. Not only that, but polyurethane elastomers are also ideal for making green tires and green tires.
According to the “China's Polyurethane Elastomer Industry Market Demand Forecast and Investment Strategy Planning Analysis Report†released by the organization, the performance of polyurethane elastomers is mainly realized by a wide range of hardness, large adjustable performance range, superior wear resistance and various processing methods. Aspects.
Although polyurethane elastomers have strong performance, they also have shortcomings. The main disadvantages are endogenous heat, high temperature resistance, and high resistance to strong polar solvents and strong acid and alkali media. Further, at normal temperature, the alcohol, the acid, and the ketone cause the polyurethane elastomer to swell and degrade, and the solvent such as chloroform or dichloromethane swells the polyurethane elastomer.
However, it does not hide, polyurethane elastomers are still excellent polymer materials, and can be widely used. Common products include cast polyurethane elastomers, polyurethane elastomers for construction, polyurethane elastomers for machinery manufacturing, medical polyurethane elastomers, and polyurethane rubber rollers. For example, polyurethane elastomers for construction have fully utilized the characteristics of light-weight polyurethane, good shock absorption and aging resistance. They have been promoted on the rails of high-speed rails and gradually replaced the traditional asphalt felt waterproof materials. For example, due to the high strength, abrasion resistance, biocompatibility, and no plasticizer of polyurethane elastomers, it has an important position in medical polymer materials. At present, it has successfully developed tracheal tube, plugging agent, etc. .
In general, the application prospects of polyurethane elastomers are very broad, and global consumption is showing rapid growth year by year. It is expected that the growth rate of global polyurethane elastomer consumption will remain at around 7-8% in the next few years. Among them, the automotive industry and footwear industry will be the main consumer market, and the two fastest growing areas.
