GQZ deep groove ball bearings have deep, uninterrupted raceway grooves. These raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial and axial loads in both directions. These bearings are particularly versatile and are:simple in design,non separable,suitable for high and even very high speeds,robust in operation, requiring little maintenance and so on.Deep groove ball bearings are the most widely used bearing type. Consequently, they are available from GQZ in many designs, variants, series and sizes. GQZ deep groove ball bearings are available for shaft diameters ranging from 3 to 1500 mm. They are available in three performance classes:GQZ standard bearings for high quality GQZ Explorer bearings for high-load carrying capacity GQZ Energy Efficient bearings for energy efficiency For specific applications, GQZ also manufactures engineered solutions, including: bearings for extreme temperatures; bearings with Solid Oil;insulated bearings;polymer bearings;NoWear coated bearings;sensor bearing units and so on.
