They are also used when the housing has to be mounted from the end of the shaft. Flanged housings provide a solution for applications that do not have a frame parallel to the shaft.
They are available in oval, circular and square formats that accommodate bearing types similar to those of plummer block housings. Take-up housings, meanwhile, are more typically used to maintain the tension in conveyor belt applications and are mounted onto a guide frame. Two-bearing housings have intrinsically aligned bearing seats, which enable rigid bearings, such as deep groove ball bearings, angular contact ball bearings and cylindrical roller bearings to be accommodated.
Two-bearing housings are typically used in applications with an overhanging load. Grey cast iron, spheroidal graphite cast iron and cast steel are the most common materials of construction for bearing housings. Grey cast iron is most commonly used and is sufficient for the majority of applications, offering a combination of high strength, good damping and good thermal conductivity. Spheroidal graphite cast iron is more ductile and therefore provides a higher degree of strength and toughness, being capable of handling loads that are almost twice as heavy than those for grey cast iron.
Where there is the threat of corrosion, bearing housings can be supplied in composite materials, in stainless steel or coated cast iron and cast steels. Appropriate housing seal selection will depend upon the operating conditions. These seals are available in a variety of designs, the most common being radial shaft seals. However, for extremely contaminated or wet environments it may be necessary to use an engineered seal comprising three- or even four-stage labyrinths in combination with an internal V ring for additional sealing effect and efficient grease purging.
Bearing housings are generally supplied as standalone devices, requiring customers to specify all additional components separately. As this can be a time consuming task, manufacturers offer complete pre-assembled bearing units or kits, which include the housing, bearing, seals, sensors and locating rings necessary to create a working bearing system.
Delivered in this way, housing kits also relieve the customer of a lot of the design effort. Once a bearing installation is up and running, the most vital consideration is lubrication.
Grease is the most widely used lubricant for rolling bearings and should be matched to meet the specific demands of the application and operating conditions; e. It is also important to consider the lubricant delivery method. Where lubrication points are difficult or dangerous to access, for example, an automatic lubrication system SKF SYSTEM 24, for example provides a safe and reliable solution. These are timed, gas or electro-mechanically driven grease cartridges that are fitted to the bearing housing lubrication point, dispensing lubricant in precise quantities at selected intervals.
This can be achieved through regular visual inspections or via a condition monitoring system, the latter being particularly relevant to critical installations. The most commonly monitored parameter is vibration, with the bearing condition being determined by analysing variations in its vibration signature. Bearing temperature is another important measurement parameter, as is periodic testing of lubricant condition using a purpose-designed test kit.
Aggregate Industries uses Pennsylvania rock crushers at this site to break up around six million tonnes of limestone every year. Each crusher incorporates a series of hammers mounted along a central rotor shaft to reduce the limestone to the required size — a process that is particularly demanding on shaft bearings, seals and drive mechanisms due to the amount of dust generated.
The previous shaft bearing housings were unable to cope, with dust penetrating the seals and contaminating the bearing lubricant. The problem was exacerbated by the poor quality of the existing bearing housing castings, which proved porous, allowing oil to leak from them.

Privacy policy. Welcome to a new way to install Visual Studio! In this version, we've made it easier for you to choose and install just the features you need. We've also reduced the minimum footprint of Visual Studio so that it installs more quickly and with less system impact than ever before. Welcome to Visual Studio ! In this version, it's easy to choose and install just the features you need. And because of its reduced minimum footprint, it installs quickly and with less system impact.
This topic applies to Visual Studio on Windows. Want to know more about what else is new in this version? See our release notes. Check the system requirements. These requirements help you know whether your computer supports Visual Studio Apply the latest Windows updates.
These updates ensure that your computer has both the latest security updates and the required system components for Visual Studio. The reboot ensures that any pending installs or updates don't hinder your Visual Studio install. Free up space. Remove unneeded files and applications from your system drive by, for example, running the Disk Cleanup app. For questions about running previous versions of Visual Studio side by side with Visual Studio , see the Visual Studio compatibility details.
You can install Visual Studio side by side with previous versions. For more information, see Visual Studio platform targeting and compatibility and Install Visual Studio versions side-by-side. To get a bootstrapper for Visual Studio , see the Visual Studio previous versions download page for details on how to do so. To do so, choose the following button, choose the edition of Visual Studio that you want, choose Save , and then choose Open folder.
Download Visual Studio. To do so, select the following button, choose the edition of Visual Studio that you want, and then save to your Downloads folder.
Run the bootstrapper file to install the Visual Studio Installer. This new lightweight installer includes everything you need to both install and customize Visual Studio. From your Downloads folder, double-click the bootstrapper that matches or is similar to one of the following files:.
Choose Continue. After the installer is installed, you can use it to customize your installation by selecting the feature sets—or workloads—that you want. Here's how. For example, choose the ". NET desktop development" workload. It comes with the default core editor, which includes basic code editing support for over 20 languages, the ability to open and edit code from any folder without requiring a project, and integrated source code control.
For example, choose the "ASP. NET and web development" workload. Review the workload summaries to decide which workload supports the features you need. For example, choose the ASP. At any time after installation, you can install workloads or components that you didn't install initially. Or, open the Visual Studio Installer from the Start menu. From there, you can choose the workloads or components that you wish to install.
Then, choose Modify. If you don't want to use the Workloads feature to customize your Visual Studio installation, or you want to add more components than a workload installs, you can do so by installing or adding individual components from the Individual components tab. Choose what you want, and then follow the prompts. By default, the installer program tries to match the language of the operating system when it runs for the first time.
