SKF double row cylindrical roller bearings are available in several designs with a cylindrical or tapered bore. The SKF standard assortment presented in this section includes:
NNU design bearings 
NN design bearings 
NNUP design bearings 

Bearing features
High load carrying capacity 
Because of their second row of rollers, double row cylindrical roller bearings are suitable for heavy radial loads.
Low friction (Roller end / flange contact area) 
The open flange design , together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
Long service life 
The logarithmic roller profile reduces edge stresses at the roller/raceway contact  and sensitivity to misalignment and shaft deflection.
Enhanced operational reliability 
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
Separable and interchangeable 
The separable components of SKF double row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
High speed capability 
The cage designs are suitable for high speeds, rapid accelerations and peak loads.
