INA NNTR55X140X70-2ZL - Yoke type track roller NNTR..-2ZL, CRB, full complement roller set, two-row, with inner ring, 3 ribs on outer ring, not pallet changer.
NNTR55X140X70-2ZL INA is ready-to-fit cylindrical roller bearings of double row design. It have particularly thick-walled outer ring with a crowned outside surface . NNTR55X140X70-2ZL INA can support high radial loads and tolerate axial loads which are due to small misalignments, skewed running or temporary contact running impacts.
