Cylindrical roller bearings – Precision series

Single-row roller bearings can sustain high radial loads and are suitable for high speeds. These bearings are separable, making their assembly and disassembly easier. Both bearing rings can be fixed when required. The modified shape of their functional surfaces prevents harmful edge stresses at the ends of the rollers.

Types

N type – An inner ring with two integral flanges for roller guidance.
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.
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.
