Hey there! So, these cylindrical roller bearings are pretty cool. They're designed to handle heavy loads and mainly bear radial loads. They have a linear contact design with the raceway, which means the friction between the rolling body and the sleeve is really low. This makes them perfect for high-speed rotation.
There are a bunch of different types of cylindrical roller bearings, like NU, NJ, NUP, N, NF, NNU, and NN. The type you need depends on whether or not the sleeve has a side.
One of the best things about these bearings is that they have a large radial bearing capacity, which makes them perfect for handling heavy loads and impact loads. They also have a low friction coefficient, which means they can handle some serious speed - their ultimate speed is close to that of a deep groove ball bearing.
If you need to install these bearings, keep in mind that high processing requirements are needed for shaft or pedestal holes. After installation, it's important to strictly control the relative deviation of the outer ring axis to avoid contact stress concentration. But the good news is that the inner or outer rings can be separated to make installation and disassembly easier.
So, where are these bearings used? You'll find them in all kinds of heavy-duty machinery, like large and medium electric motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, and hoisting transport machinery. They're basically perfect for anything that needs to handle a heavy load and spin really fast!
