Yoke Type Track Roller NNTR55X140X70 2ZL 55x140x70 mm
Item number:
NNTR55X140X70-2ZL
Item features:
The full complement roller set yoke type track roller NNTR55X140X70-2ZL can support very high radial loads and continious axial loads due two its double-row design. Due to the profiled outer surface of the outer ring, it can compensate for axial loads from minor misalignments and skews.

Features
- based on full complement, double row cylindrical roller bearing; the two rows of rollers are guided separately from each other by the three ribs of the outer ring; two loose flange rings are used for axial support
- since the bearing does not have a cage, it is particularly stable due to the highest possible number of rolling elements and supports very high radial loads, in addition, the space between the roller sets, which is filled with grease, reduces friction, so relatively high, aslo constantly acting axial loads due to slight misalignment defects or skew, can be accommodated.
- with inner ring, can be used if the surface of the shaft is not suitable as a raceway
- with axial guidance
- the axial guidance is effected with the central rib and the rolling elements
- seal: sealing shields with lamellar ring on both sides for high sealing effect
- In addition to this article, we can also offer bearings of the brands FAG, KOYO, NSK, SKF, SNR, etc. on request.
