Feature conical rollers arranged at precise angles to handle heavy axial loads and moderate radial loads. Provide high rigidity and alignment capability through matched raceway geometry. Require precise mounting and adjustment to maintain optimal preload conditions.

Common Types:
Single direction (AS series); Double direction (ASD series); With flat washers (ASNU series); Aligning seat washers (ASU series); Special coatings (Suffix C).

Typical Applications:
Heavy-duty gearboxes, industrial presses, machine tool spindles, crane slewing rings, marine propulsion systems, wind turbine pitch controls, and mining equipment.
