NAU4909UU IKO

Part Number: NAU4909UU

Brand: IKO

Bearing Type: Caged Roller Bearing

Dimension(s):
Inside Diameter (d) = 45mm
Outside Diameter (D) = 68mm
Width (C) = 22mm
Radius (rs min) = 0.6mm

Other Dimension(s):
(J) = 51mm
(Ew) = 61mm

Load Rating(s):
Basic Dynamic Load Rating (N) = 24800
Basic Static Load Rating (N) = 32800

Speed Limitation(s):
Allowable Rotational Speed (r/min) = 3500

Additional Notes:
1). This bearing is supplied with pre-packed grease.
2). This bearing has an oil groove and oil hole on the outer ring.
3). The allowable rotational speed applies to grease lubrication. Considering that the axial load acts under practical operating conditions, up to 1/10 of this value is recommended for actual use.

More Information:
These bearings are suitable for high-speed rotations and fluctuating loads. Also, as the axial distance between the double-row rollers is comparatively large, large moment loads can be supported. Caged roller bearings with seals incorporate seals on both sides. Synthetic resin rubber seals are excellent in the prevention of dust penetration and grease leakage, providing an excellent sealing effect.
