Here are some examples of applications in which spherical roller bearings might be used: Vibration Screen Bearing, Wind turbine bearings, Papermaking mills bearings, Continuous Caster bearings & etc.

Spherical Roller Bearings have many different structures, such as CC type, CA type, E type from SKF and MA type, MB type, E1 type from FAG. Now let me give you a detailed introduction of the difference between these designs.

Key Factors of Electric Motor Bearing Design –Outline dimensions–Load size and direction–Speed requirements, constant/variable/high–Material of motor shaft and housing–Power take-off transmission form–Motor installation form–Vibration level requirements–Noise level requirements–Temperature requirements–Bearing life–Lubrication form–Maintenance–Condition monitoring–Sealing and protection Common Configuration of Electric Motor Bearing –Horizontal Motor 1. DGBB+DGBBCross positioning configuration, suitable for small and medium-sized motors, low maintenance requirements, axial guidance is not a key parameter, non positioning bearings have spring preloading2. Sealed DGBB + CRBSuitable for large motors, with heavy load on the drive side and axial expansion inside the bearing3. CRB + A pair of Angular Contact Ball Bearing Face to FaceFor motors with bidirectional axial load and heavy radial load, or for occasions with strict requirements on axial displacement4. DGBB + A pair of Angular Contact Ball Bearing Face to FaceIt is used for small motors with axial load and moderate radial load, or for occasions with strict requirements on axial movement. Deep groove ball bearing is with spring preload5. CRB + CRB & DGBBFor large motors. The deep groove ball bearing is free in radial direction, and the O-ring is used to prevent the outer ring from rotating6. SRB + SRBFor extra large motors and heavy load occasion –Vertical Motor 1. DGBB + DGBBFor small and medium-sized…
