Double row cylindrical roller bearings

Description

Double row cylindrical roller bearings are available in various designs with cylindrical or tapered bores. Standard products available in this section include:

NNU type bearing

NN type bearing

NNUP type bearing

Bearing characteristics:

High load carrying capacity

Due to their second row of rollers, double-row cylindrical roller bearings are suitable for larger radial loads.

Low friction (roller end/rib contact area)

The open flange design, along with the roller end design and surface finish, promotes a lubricant film that reduces friction and results in a higher basic load rating.

long lasting

The logarithmic curve profile reduces edge stresses at the roller/raceway contact and reduces sensitivity to misalignment and shaft deflection.

Improve operational reliability

The surface treatment of the roller and raceway contact surfaces is conducive to the formation of hydrodynamic lubricating oil film.

separable and interchangeable

The separate components of double row cylindrical roller bearings are interchangeable. This facilitates installation, disassembly and maintenance inspection.

High speed capability

Cage design is suitable for high speeds, rapid acceleration and shock loads.
