350212X2 Double-Row Tapered Roller Bearing

Double-Row Taper Configuration: Delivers double the load density, managing severe simultaneous radial and bi-directional thrust loads.
Rigid Axial Locking: Prevents all axial play, ensuring precise positioning of wheel hubs or heavy industrial drivetrain shafts.
Advanced Fatigue Resistance: Forged from high-purity, vacuum-degassed bearing steel to prevent subsurface micro-fracturing under heavy loads.

Deep Application & Technical Narrative:

The 350212X2 is a massive double-row tapered roller bearing engineered for the drive axles, heavy-duty wheel hubs, and primary reduction gearboxes of large commercial trucks, buses, and industrial machinery. By incorporating two rows of opposing tapered rollers into a unified assembly, the 350212X2 provides extraordinary radial capacity while securely locking the shaft against intense axial thrust forces originating from both directions. This eliminates any possibility of shaft axial drifting. In our dedicated assembly workshop, we execute meticulous manual inspections on every 350212X2 unit. We physically verify the factory-set internal clearances and roller alignment across both rows to ensure perfect balance. This hands-on quality process delivers an ultra-reliable, high-rigidity component built for heavy commercial operations.

Targeted Technical Clarifications (FAQ):

Q: Does this double-row bearing require manual adjustment of clearance during installation?
A: No, the internal clearance of the 350212X2 is precisely preset at the factory, greatly simplifying installation and eliminating the risk of human error during setup.
Q: What type of grease is recommended for this bearing in heavy truck hubs?
A: A heavy-duty NLGI Grade 2 grease with extreme pressure (EP) additives and high thermal stability is strongly recommended.
