NATR and NATV are designations for support rollers with flange rings and a relubrication feature. Here's what each term means:

NATR (support rollers with flange rings, and a relubrication feature ): NATR bearings are support rollers designed for applications where radial loads need to be supported.

The "NATR" prefix stands for "N" (needle roller), "A" (support roller), "T" (with flange rings), and "R" (with a relubrication feature). These bearings typically have a thick-walled outer ring with a crowned profile to support the roller and prevent edge stresses. They also feature flange rings on both sides of the outer ring to provide axial guidance for the roller.

NATV (support rollers with flange rings, and a relubrication feature, full complement ): NATV bearings are similar to NATR bearings but have a full complement of needle rollers without a cage.

The "NATV" prefix stands for "N" (needle roller), "A" (support roller), "T" (with flange rings), "V" (full complement), and "R" (with a relubrication feature). These bearings offer higher load-carrying capacity but may have lower operational speeds compared to NATR bearings.

support rollers with flange rings and a relubrication feature, such as NATR and NATV bearings, are commonly used in various applications, including cam followers, track rollers, and conveyor systems.

the relubrication feature allows for maintenance and prolongs the service life of the bearing by ensuring proper lubrication. the flange rings provide axial guidance for the roller and help prevent misalignment during operation.
