Detailed description
NNTR...-2ZL-TYPE SUPPORT ROLLERS
The internal design layout of the non-separable NNTR...-2ZL-type support rollers similar to that of double row cylindrical roller bearings.
Since the outer ring has three fixed lips these support rollers can accept high thrust loads.
The loose ribs on the inner rings are retained by incorporated lamellar rings which also act as labyrinth seal.
These lamellar ring seals act as efficient sealing system against harsh environment, i.e. under presence of dust and scale.
