Reference Speed: 8000 r/min
Limiting Speed: Approx. 11000 r/min r/min (can be higher under oil lubrication conditions, depending on the lubrication method)
Model Analysis and Application Characteristics
Model Structure: "7" represents angular contact ball bearing, "408" represents the size series and inner diameter code, "B" indicates a 40¡ã contact angle, and "M" indicates a machined brass cage.
Force Characteristics: Can withstand radial loads and unidirectional axial loads simultaneously; single-row designs require paired installation (back-to-back/face-to-face) to withstand bidirectional axial forces or overturning moments.
Typical Applications: Machine tool spindles, high-speed motors, steam turbines, automotive differentials, and other high-speed applications requiring high axial rigidity.
