The NATV20-X-PP-A INA is a track roller or support roller with needle rollers. These rolling elements combine high load capacity with a compact design. 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 NATV20-X-PP-A 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.
