Double row needle roller bearing with machined rings, with flanges and an inner ring
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.
