Key Benefits:

1. High combined load capacity — L725349 – L725311 bearing handles heavy radial loads and significant axial (thrust) loads in one direction.
2. Robust tapered-roller geometry — offers reliable load distribution and strong shaft support under demanding conditions.
3. Separable cup-and-cone design — simplifies mounting, inspection, and replacement for faster maintenance.
4. Hardened bearing-steel rings and rollers — improve wear resistance and extend service life.
5. Steel cage for durability — maintains roller spacing under high speed and shock loads.
6. Precise dimensions and tolerances — ensure accurate fit, alignment, and consistent performance.
7. Flexible mounting options — pair in back-to-back, face-to-face (X/O) or tandem arrangements to control preload and stiffness.
