GQZ's precision bearings and bearing-related products have a wide range of customers, mainly OEMs and major distributors. GQZ offers all kinds of bearings such as deep groove ball bearings, self-aligning ball bearings, spherical roller bearings, taper roller bearings, thrust ball bearings, cylindrical roller bearings and many more other types. Today, we are going to introduce spherical roller bearings.


In GQZ, the spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Despite what their names may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a (barrel like) profile that makes them appear like cylinders that have been slightly over-inflated(i.e. like a barrel).


The spherical roller bearing was invented by engineer Arvid Palmgren and was introduced on the market 1919 by SKFIts bearing rings and rolling elements can be made of a number of different materials, but the most common is "chrome steel", (high carbon chromium) a material with approximately 1.5% chrome content. Such "chrome steel" has been standardized by a number of authorities, and there are therefore a number of similar materials, such as: AISI 52100 (USA), 100CR6 (Germany), SUJ2 (Japan) and GCR15 (China).


GQZ Spherical bearings are used in countless industrial applications with heavy loads, moderate speeds and possibly misalignment, such as gearboxes, wind turbines, continuous casting machines, material handling, pumps, and off-road vehicles and so on.
