Smart technology communicates with new bearings
SKF Insight introduces an innovation in smart technologies specially developed for integration into new SKF bearings. This new, integrated diagnostic technology can make condition monitoring more widely applicable, especially in applications where it was previously impractical or impossible. Ultimately, the technology provides greater control over the life cycle of machinery, leading to lower total costs while increasing reliability and machinery uptime.
SKF Insight technology monitors the conditions that can cause bearing damage from the first microscopic effect as it happens, allowing users to take remedial action to avoid increased damage in the bearing and prevent escalation. (Conventional condition monitoring measures parameters such as vibration and temperature, which indicate problems only after bearing damage has occurred.) In addition, by monitoring the load directly on the bearing, SKF Insight technology can measure the load actually experienced by the bearing to determine the direct effect of any changes in operating conditions, which could potentially have an adverse effect on the bearing.
Among key features, SKF Insight includes miniaturization and packaging of sensor technologies to measure critical parameters such as RPM, temperature, velocity, vibration, load, and lubrication; the “smart” bearings can generate their own power for operation; intelligent wireless technology packaged inside the bearing enables communication within environments where traditional WiFi cannot operate, and the bearings can form a “mesh network” to send information relevant to their condition for analysis.
SKF Insight solutions also include SKF Asset Diagnostic Services, which connect users to SKF industry application knowledge, a global network of SKF Remote Diagnostic Centers, global IT solutions, and makes all application data accessible in a single cloud-based system. This collective data reflects a huge breadth of knowledge and experience in diagnosing and solving machinery reliability issues in applications across all major industries worldwide.
SKF Insight application-specific solutions are under trial with key industries, including wind energy, railways, and metals with others in development.
Clear Rigid PVC resists UV in outdoor tubing applications
A new, rigid vinyl compound with a specially-developed, UV-blocking formulation provides clarity for photobioreactors and other outdoor tubing, along with high gloss and toughness for weatherable profile applications.
Apex RE 9118A is a transparent compound with less than 15 percent haze. The UV-blocking formulation substantially reduces the harmful effects of ultraviolet radiation on the PVC while permitting passage of wavelengths that are essential in processes like algae farming for biofuel and other applications. The tensile, flexural, and impact properties of the compound are comparable to those of standard general-purpose rigid vinyl.
The new material is the only one available from a diversified PVC compounder that combines good clarity and high resistance to UV, said Michael J. Renzi, business development manager for the Vinyl Division of Teknor Apex. “By virtue of its lower cost, lighter weight, and greater resistance to breakage, rigid vinyl provides a superior cost-performance alternative to the glass piping used in ‘green energy’ applications, as well as to high-cost engineered thermoplastics such as polycarbonate,” he said. “Our PVC compound withstands continued exposure to sunlight while allowing passage of energy needed for bioprocessing and enabling technicians to monitor the status of their systems.”
