Introduction About Deep-groove ball bearings 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 Deep groove ball bearings are the most widely used bearing type. Consequently, they are available from SKF in many designs, variants, series and sizes. Deep groove ball bearings are available for shaft diameters ranging from 3 to 1500 mm. They are available in three performance classes: a.standard bearings for high quality b.Explorer bearings for high-load carrying capacity c.Energy Efficient (E2) bearings for energy efficiency For specific applications, It also including: bearings for extreme temperatures DryLube bearings bearings with Solid Oil insulated bearings polymer bearings NoWear coated bearings sensor bearing units

Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. Factors that influence spherical roller bearing performance Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers, raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces. Main factors which influence spherical roller bearing performance include, but are not limited to: Symmetrical rollers Roller tolerances Special roller profile

�Features a�Lower speed than the ball bearing with the same dimension b�High precision c�Low noise and small vibration d�Mainly withstand radial load e�Can withstand a litter axial load if outer ring and inner ring have ribs �Designs Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, single and double row full complement bearings (without a cage) complete the standard assortment listed in this catalogue. Double row cylindrical roller bearings mainly in the NNU design and the NN design(fig 2). The bearings are separable, i.e. the ring with integral flanges together with the roller and cage assemblies can be mounted separately from the other bearing ring or all bearing components can be mounted separately. This facilitates the mounting, inspection and maintenance of these bearings.
