NU 313 ECJ Single Row Cylindrical Roller Bearing 65x140x33 Mm
NU 313 ECJ Single Row Cylindrical Roller Bearing 65x140x33 mm
Cylindrical Roller Bearing, NU 313 ECJ, 65x140x33 mm, Steel Cage, Single Row, No Seal, No Separable; No Snap Ring, Relubricatable, C0.
The NU313ECJ is a single-row cylindrical bearing with NU design. The outer ring of this bearing has two rigid ribs, while the inner ring has none. As a result, NU bearings are only capable of supporting radial forces. This bearing type is commonly used as a floating bearing. Floating bearings allow axial displacement of the shaft relative to the housing in both directions. This is necessary in applications where the shaft material shrinks or expands due to temperature changes (thermal expansion). NU bearings can also be used as support bearings by combining them with HJ angle rings (available separately). Support bearings can support radial forces and also axial forces in a single direction.
EC: Optimized Internal Design Incorporating More And/Or Larger Rollers And With Modified Roller/End Flange Contact.
J: Pressed Steel Cage, Roller Centered, Unhardened
