Medias description
Yoke type track roller NNTR..-2ZL, CRB, full complement roller set, two-row, with inner ring, 3 ribs on outer ring, not pallet changer
The NNTR90X220X100-2ZL INA is a track roller or support roller with cylindrical rollers. These rolling elements combine a high load capacity with reasonable shock resistance. Track rollers are designed for use with various types of tracks. Thanks to a thick-walled outer ring, they can withstand high radial loads. Axial loads due to alignment errors or misalignment can be absorbed in both directions. Yoke type track rollers are suitable for mounting on a shaft. They are not mounted in a housing bore, but a flat (counter) track provides support.
The NNTR90X220X100-2ZL INA has a full complement design. The absence of a cage allows for a greater number of rolling elements, making this track roller radially highly loadable. Full complement track rollers are also more shock-resistant than track rollers with a cage. However, the maximum rotational speed is lower than that of caged variants. Common applications of track rollers include conveyor systems, linear guidance systems, and cam mechanisms.
