Plasticine is very common in everyday life, but it usually only appears as a child's toy and it will not be attractive to adults. Recently, researchers from the University of Dublin and the University of Manchester have made this toy into a highly sensitive sensor called G-putty. After adding graphene material to plasticine, the resulting G-putty has excellent electrical conductivity and can be used to make highly sensitive sensors. G-putty can be used to detect some very slight shocks and deformations, even a small spider on the crawl can also be detected, which fully demonstrates the high sensitivity of the material. In addition, according to Professor Jonathan Coleman, chief research officer, G-putty can also be placed on the human body and used to measure major indicators of the body such as breathing, pulse and blood pressure. It is said that its sensitivity is several hundred times that of conventional sensors, which also has a broad application prospect in the medical field. Prof. Jonathan Coleman said that wearable devices that monitor physical health are now getting more and more attention, and the highly sensitive nature of G-putty will make it very promising in this area.
Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
Cylindrical Roller Bearings are designed to carry heavy radial loads. Our cylindrical roller bearings are made with a single row, two rows, or multi-rows of rolling elements to meet an application's radial load requirement. The radial Roller Bearing is available in many standard series and configurations, they are widely used in multiple industries. The combination of high load capacity, moderate speed rating, and industry interchangeability make it one of the most popular bearing designs. These cylindrical roller bearings are produced in ISO series metric, ABMA series metric and inch, journal type, Full Complement series, multi-row series, and cluster mill sizes. These bearings are dimensionally interchangeable to same numbered and sized bearings in the industry. Components of journal bearings and other standard series are made interchangeable with other manufacturer's components. Many mounting arrangements can be achieved with the multiple configurations available with the same load capacity for a given I.D., O.D., and width. Our cylindrical roller bearings can be manufactured in sizes from 3" bore diameter to 84" outside diameter. Internal radial clearances and cage designs can be engineered to your specific application when special applications are encountered.
