NU 2244 ECMA Single Row Cylindrical Roller Bearing 220x400x108 Mm
NU 2244 ECMA Single Row Cylindrical Roller Bearing 220x400x108 mm
Cylindrical Roller Bearing, NU 2244 ECMA, 220x400x108 mm, Brass Cage, Single Row, No Seal, No Separable; No Snap Ring, Relubricatable, C0.
Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NU design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
EC: Optimized Internal Design Incorporating More And/Or Larger Rollers And With Modified Roller/End Flange Contact.
M: Solid Brass Cage, Two Piece, Roller Guided
