Double-row cylindrical roller bearings (NN…)

Double-row cylindrical roller bearings are suitable for heavy radial loads, because of their high rigidity and load capacity. These bearings are designed for spindles which are subject to high rigidity requirements, most often lathe spindles.

Types:

NN type – Two ribs on the inner ring, no rib on the outer ring

NNU type – Two ribs on the outer ring, no rib on the inner ring

E44 – Bearings with the lubricating groove and lubricating holes on the outer ring

Two types of cages: Brass (MB), special plastic PPS cage (TB)

These bearings are also produced with the tapered bore (K or KR).

Accuracy: P5, P4, P2 according to ISO, P4Y special accuracy class. Narrow tolerance field: At the lower limit of the tolerance field according to ISO.

Radial clearance: CC1, standard for bearings with cylindrical bore, CC0, standard for bearings with tapered bore, CCG, special radial clearance.

The resulting radial clearance can be adjusted to the requested value by axial displacement of the inner ring on the conical seat of the pin.

Sealed double-row cylindrical roller bearings are also produced and are resistant to very high and shock load.

Bearing series: NN 30.., NN39.., NN49.., NNU49..,
