Intelligent bearings are fitted with built-in sensors to measure temperature and pressure bearing already exist for quite some time, however, they are limited to a small number of trucks on the trial, mainly due to the fault detection means fixed road than airborne detector unit cost province, good benefits. However, when the railway company ECP brake technology standardization, this situation can be changed. So far no one can really do it, where there is an economic issue.

Continue to increase fixed detection device, so that you get intelligent detection network, and its cost-effectiveness is much higher than that, then the development of airborne detector means is not it make more sense than the alternative view is that if you use the better maintenance standards and good working method, then you do not necessarily need such a fault was detected. This in a way is a kind of compromise. "No positive and negative opinions of standardized parts supplier to the benefits of standardization challenge, but in some cases, standardize and limit technological innovation, pattern conveyor belt which is particularly suitable for rolling bearings to a particular new technology push This industry is quite hard to railway industry to engage in this work could not keep pace with the speed of the bearing supplier of rolling bearings AAR specification is still based on performance rather than manufacture it hindered the integration of new products.

For seven years, we have been developing new norms, but we have yet to implement. In addition to safety outside, AAR also consider standardization. Standardization is good in itself, but also has its drawbacks. For example, whenever you try to launch a new bearing technology, maintenance standard or amendment, this process is very difficult. We Timken Company spent a few years only to short bearing to be recognized, but many are not purchased by railway companies, because they do not want to stock a number different from the previous use of spare parts for the maintenance of plant maintenance. Many private owners often complain, because usually they are the first to adopt new technologies. However, when their car to the railway company's maintenance plant repair, not always encourage railway companies to adopt new technology to replace the existing technology.
