Description
The SKF NATV 12 PPA is a premium yoke-type track roller designed for demanding motion systems where durability and reliability are essential. Built on a single-row needle roller bearing with an inner ring, it provides a high radial load capacity while maintaining compact dimensions. Its crowned outer ring profile ensures smooth performance on tracks, compensating for minor misalignments, skew, or tilt.
To enhance operational life, the bearing is equipped with flange rings that guide the outer ring axially, allowing it to withstand axial loads caused by misalignment. The integral contact seals on both sides protect against contaminants, while the relubrication feature ensures consistent performance and extended service intervals. Factory-supplied with grease and sealed, the NATV 12 PPA arrives ready for immediate mounting, minimizing downtime.
With its robust bearing steel construction, thick-walled outer ring, and reliable sealing system, this support roller offers outstanding resistance to wear and long service life. It is well-suited for conveyor systems, cam drives, and track-type applications where high loads, consistent lubrication, and minimal maintenance are critical.
