Key Features:

1. Single-row tapered roller design supports heavy radial loads and one-direction thrust — delivers stable shaft support under combined loading.
2. Conical raceways and tapered rollers distribute load evenly and increase stiffness — reduce edge stress and improve running accuracy.
3. Separable cone 2558 and cup 2523 simplify mounting, inspection, and replacement — service each component without dismantling the whole assembly.
4. Hardened bearing-steel rings and rollers resist wear and extend service life — heat treatment improves fatigue strength for continuous duty.
5. Robust cage keeps rollers evenly spaced at speed and under shock — prevents roller skew and uneven wear at high RPM.
6. Suits gearboxes, axles, and heavy machinery with combined loads — performs reliably in demanding industrial environments.
