Cylindrical bore type for 4.724 in. / 120 mm. shaft diametr, outer ring surface is cylindrical.
The bearing rings are made of through-hardened carbon bearing steel. Ceramic rolling elements, made from silicon nitride.
Principal dimensions is 4.724х7.087х1.102 in. equal to 120х180х28 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.
The ceramic rollers protect bearings from electrical damage, extending their service life and improving performance, even in harsh conditions.
