NAST-ZZ-Cam Roller

Request Quote

The NAST-ZZ model is a separable type of roller follower, meaning its components (outer ring, inner ring, and needle roller cage) can be separated, facilitating easy handling and mounting. It features a shielded (ZZ) structure, incorporating a pair of side plates on both sides of the inner ring to form a labyrinth seal. This shield structure helps in preventing foreign substances from entering the bearing, though it is not a full-contact seal like the ZZUU (sealed type).
