NNTR90X220X100-2ZL track roller bearings, Support rollers, with flange rings, with an inner ring
Get high-quality NNTR90X220X100-2ZL track roller bearings with flange rings and an inner ring from our factory. We provide reliable support rollers for various needs.
Support rollers with flange rings are non-separable units
This bering have different flange designs: 1.pressed-on flange rings (NATR and NATV designs) 2.loose flange rings (NUTR, PWTR and NNTR designs) 3.accommodate axial loads that can occur because of skew or tilting NNTR ...2ZL design support rollers are based on double row full complement cylindrical roller bearings. NNTR...2ZL Series bearing have an outer ring with three integral flanges, which guide the roller sets axially. NNTR...2ZL Series bearing have an inner ring with two loose flange rings, which guide the outer ring axially via the roller sets. This bearing have a relatively large grease quantity between the two roller sets and fitted with a lamellar seal on both sides, inserted into recesses in the shoulders of the flange rings and the outer ring, making the support roller non-separable. It accommodate very heavy radial loads and relatively heavy axial loads that can occur because of skew or tilting.
