ACB3748 Headset Bearing 37x48x7 45

ACB3748 Headset Bearing 37x48x7 45 degree chamfer on inner

Typical Applications: Acros AI70 Headset Lower Cup

Installation Notes: The lower bearing must be handled with great care - it is internally angular contact which does rely on the inner and outer races to have the play 'dialed out'. To achieve this, the races are pressed together and can easily separate when removing fork (which if not careful, can result in the ball bearings falling out). There is no alternative design/construction option for this bearing. We cannot be held liable in future, if mishandling or bad installation results in races separating.
