While bearings are critical components in vital aviation systems, they account for about 51% of all electric motor failures. They play the important roles of guiding and constraining motion, reducing friction, and providing support, so failure(s) can occur in many forms and have various detrimental effects. Failures vary by bearing type and function, but typically include normal wear and tear, lubrication issues, contamination, or electrical damage that affects bearing surfaces. As many of these issues are preventable, this blog will further explore the different types of sleeve bearings, their applications, and how to avoid bearing failure through repairs and routine maintenance.
Bearings are useful components for a multitude of assemblies and industries, providing bearing surfaces for components to both restrict motion and to reduce friction between moving components. Through implementation within an assembly and lubrication, bearings can slow down the wear of components, facilitating their motion while extending their service lives. Within the realm of aerospace, aircraft bearings can be used to take on radial loads, thrust loads, and a combination of the two. Antifriction bearing and sleeve bearing parts are common to aircraft assemblies, both providing their individual abilities to aid in flight operations. In this blog, we will discuss sleeve and antifriction bearings so that you may understand how each functions, as well as how they are used within aircraft.
For aircraft construction, bearings and seals are almost always utilized in rotating or rolling components. Bearings are utilized to constrain movement to specific motions and axes, and work to reduce the friction between moving components. Bearings can also work to disperse stress of the component loads. Seals on the other hand, help prevent contamination, such as dirt, from entering the bearing gaps, as well as encases bearing lubricant inside. So what are some examples of the types of bearings and seals that can be used?
Motion & Gear Bearing (MAG bearing) was established in 1992 with headquarter in hub-Shanghai, Wafangdian, which is a well known city for ball bearing industry since the last century. MAG is an international bearing distributor with more than 500 employees, owing more than 300 equipments and over CNY 50 million Yuan fixed valuables. The company is an important supplier for various industries such as mill industry, mining and lumber industry, automobile industry etc.
Romax, the global leader software, analysis and services for gearbox, bearings and driveline systems, and number six globally for bearings and bearing components, alongside the ZWZ Group, the top 100 enterprise for mechanical parts in china, announced last month the partnership on building a global bearing simulation technology center which will produce many different bearing with different bearing components. This agreement is a symbolization of a new stage of partnership between Romax and ZWZ Group. This symbolization will produce a considerable influence on the technological progress of the two companies.
There's no doubt that Rolling Bearings can prove to be an expensive investment over time. But is there a smarter way to buy? The final decision to make a purchase on a bearing is much more cost-effective when you take into account the whole life costs, also known as the total cost of ownership. Basically, you must consider what it will cost you over the life-span of the product, not just at the initial purchase. This is definitely a preferable alternative if you’re interested in making your dollar work for the long-term and saving some money over time.
