Technical Specification 
The M88043/M88010 tapered roller bearing is designed for maximum load-carrying capacity and durability in demanding applications. Its inch-series geometry allows for precise fit in automotive axles, construction machinery, and mining equipment. Manufactured from premium bearing steel, the raceways are hardened and ground to reduce friction, minimize heat generation, and extend operational life. The optimized roller arrangement ensures smooth load distribution, reducing wear and vibration under heavy stress. Easy installation and maintenance make this bearing cost-efficient for large-scale industrial use. DSBR’s quality control guarantees global-standard performance, making it a trusted solution for OEMs and distributors worldwide.
