This series of radial cylindrical roller bearings are especially thought for all those applications where self holder-up systems for axial loads are provided.
The main stud, on which they are mounted, is made of high strength steel with very good welding properties.
It is carefully manufactured and represents a big help for the end users of these bearings to make their application easier.
These radial bearings can be supplied both long life lubricated with water repellent, meral-oil-base grease, suitable for high pressure and low speeds and with labyrinth seals. This means that relubrication
has to be made through the lubrication hole in the middle of the stud to be welded.
These bearings are mainly used in the carriage of the masts in retractable lift trucks, in combination
with slides in antifriction material.
