Product Introduction

The AK544090/116 is an extra-large diameter, heavy-duty imperial tapered roller bearing crafted for the most extreme industrial duty cycles. Precisely sized at 228.6 x 295.275 x 33.338 mm, this high-capacity cup and cone set provides immense structural support for massive radial payloads and severe thrust forces. Forged from vacuum-degassed chrome alloy steel, the AK544090/116 features crowned rollers that perfectly align under heavy torque, eliminating destructive edge pinching. Through strict enterprise quality control, this bearing guarantees prolonged fatigue life for large-scale mining equipment, steel manufacturing infrastructure, and heavy commercial drivetrains.

Applications

Large-scale mining crushers and heavy off-highway trucks.
Steel mill rolling equipment and rotary kilns.
Heavy-duty marine gearboxes and propulsion shafts.

FAQ

Q: Does the 'AK' prefix indicate a specific modification?
A: Yes, 'AK' and similar prefixes generally denote specific OEM modifications or internal geometry optimizations (like specialized radii or cage designs) tailored for high-stress applications.
Q: Are material test certificates available for bulk orders?
A: Absolutely. We provide comprehensive Certificates of Analysis (COA) detailing material composition and dimensional accuracy with every bulk shipment.

OEM & Custom Service

We partner directly with heavy equipment OEMs to supply specialized anti-corrosion surface treatments, heavy-duty custom packaging, and guaranteed volume fulfillment for aftermarket rebuild programs.

Packing & Delivery

Bearings are heavily coated with industrial-grade rust inhibitors, sealed in heavy-gauge VCI polymer barrier bags, and packed into reinforced wooden export crates designed to withstand rough port handling.
