Key Features:

1. Single-row tapered roller design for combined radial and axial load support. Tapered geometry ensures stable rolling contact and handles heavy radial loads plus thrust in one direction.
2. Precision-machined raceways and rollers for smooth operation and low vibration. Fine surface finish and accurate profiles reduce noise, friction, and bearing wear.
3. Hardened chrome steel construction for high wear resistance and long service life. Heat-treated bearing steel resists fatigue and maintains performance under continuous use.
4. Tight dimensional tolerances for easy installation and reliable alignment. Accurate dimensions simplify mounting, reduce rework, and ensure consistent fit on shafts and housings.
5. Robust cage design to maintain roller spacing at high speeds and under shock loads. Sturdy cage construction prevents roller skewing, improves stability, and extends service life in demanding conditions.
