Description
ISB slewing bearings in the NBL standard series have one row of four contact point ball bearings with spacers in Nylon.
They are comprised of forged rings, which are machined to form a structure in which both rings are flanged, without gear teeth. ISB slewing bearings in the NBL standard series are supplied pre-greased.
ISB slewing bearings in the NBL standard series represent a good compromise between performance and rigidity, thanks to their high versatility and easy assembly due to the double flange.
Their double seal means they can also be installed in outdoor or dusty environments.
ISB NBL standard series slewing bearings can also rotate at high speed (30 rpm) under low loads.
ISB slewing bearings in the NBL standard series can be supplied in NBL.20 S and NBL.30 S versions for general applications,
or in NBL.20 P and NBL.30 P precision versions, with almost no clearance in cases where the application requires extreme
rigidity.
