Cylindrical bore type for 3.15 in. / 80 mm. shaft diametr, outer ring surface is cylindrical.
Made of hardened carbon chromium bearing steel, most widely used material for bearing rings and rolling elements.
Principal dimensions is 3.150х5.512х1.024 in. equal to 80х140х26 mm.
Without seals.
Machined brass cage.
Metric series product.
Single row cylindrical roller bearings with cage are designed to operate with high radial loads and speeds. The roller has a larger than ball contact area perpendicular to the bearing axis.
NU type bearings have two rigid ribs on the outer ring and no flanges on the inner ring. Axial displacements of the shaft relative to the housing are possible in both directions within certain limits.
Separable design provides easier mounting and maintenance, and enables the bearing components to be interchanged.
NU design bearings are used as non-locating bearings, they cannot guide the shaft axially in either direction. They can be combined with an L-section ring HJ to locate and use as semi-locating bearings.
