NU 332 ECM/C4VA301 Cylindrical Roller Bearing 160x340x68 Mm For Railway Vehicle Traction Motors
NU 332 ECM/C4VA301 Cylindrical Roller Bearing 160x340x68 mm For Railway Vehicle Traction Motors
Cylindrical Roller Bearing, NU332ECM/C4VA301, 160x340x68 mm, Brass Cage, Single Row, No Seal, Inner Ring - Both Sides Separable; No Snap Ring, Relubricatable, C4.
The NU332ECM/C4VA301 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.
M: Two-Piece Machined Brass Cage, Roller Centered
C4: Bearing Internal Clearance Greater Than C3.
