High radial capacity for compact assemblies

Practical benefits

Robust double row Skf design: You achieve high radial load carrying capacity within compact machinery thanks to the engineered double row roller arrangement.
Separable rings simplify installation: You can mount the inner and outer rings independently to allow precise shaft fits and easier maintenance inspections.
Convenient relubrication features: Built-in lubrication holes in the outer ring let you apply fresh grease efficiently, ensuring smooth and lasting operation.

In a nutshell

The right choise for

Equip compact industrial machinery and gearboxes for heavy radial demands with the Skf na 6911 double-row needle roller bearing. Thanks to its engineered double-row roller configuration, you can support high dynamic and static radial loads within tight installation spaces. The included solid inner ring allows reliable operation directly on standard shafts that are not hardened or ground. Featuring a separable design, it lets you mount the inner and outer rings independently onto the shaft and housing for easier fitting and maintenance checks. Built-in relubrication features in the outer ring ensure simple maintenance and long-lasting operation.

Product description

Double row needle roller bearings incorporate cylindrical rollers that are small in diameter relative to their length. Owing to their large number of rollers, the bearings have a high load carrying capacity. The outer ring includes flanges to guide the roller and cage assemblies and has features to facilitate relubrication. It is possible to assemble the inner and outer rings separately, permitting interference fits for shaft and housing and enabling easy maintenance inspections.
