Description

These needle roller bearings are particularly suitable for applications requiring ability to stand heavy loads and a very accurate axial placing. Radial needle roller bearings ZARN..L consist in caged radial needle bearing supplied with an outer ring having a big thickness, its lateral surfaces are used as raceways for two thrust needle bearings or roller bearings; the inner ring of radial needle roller bearing is holded sideways between the ring of the thrust bearing and it works as a spacer for the axial bearing. A ZARF..L bearing has the same characteristic of a ZARN..L type, but it’s different from it because these bearings have the outer ring of radial bearing that is higher, creating in this way a flange provided with fixation holes. They are suitable for applications requiring low speeds and lighter loads. Under request for these needle roller bearings special oil seals can be supplied : their special duty is to protect them from external factors. It is very important to carefully follow assembling operations, as these bearings have to be mounted on very rigid parts: the outer ring has to be locked against one housing step, avoiding in this way any kind of axial movement while loading.
