Spherical roller bearings are inherently self-aligning and very robust. They have two rows of rollers which make the bearings able to carry heavy loads. The present WQK range of spherical roller bearings mainly is MB type. WQK can provide a wide range of sizes of several ISO Dimension Series and also includes special designs, for example, for vibrating screens and other applications. Special bearings can also be customized as required based on the standard bearings.
