AC Ball Bearing (AC-6304ZZ)

NTN

A bearing with the same main dimensions as a standard bearing, but with an O-ring mounted in 2 grooves provided on the outer diameter of the outer ring.
[Features]
·Ideal for use when creep may occur in places where the outer ring cannot be squeezed due to the action of the outer ring rotational load.
·Since it can move in the axial direction, it can be used as a free-side bearing that allows elongation due to thermal expansion of the shaft.
[Application]
·Ideal for parts where creep is likely to occur, such as bearings for motors.
