LL639249 is an inch-series tapered roller bearing cone designed for combined radial and axial loads. It is paired with the LL639210 cup to form a complete single-row tapered roller bearing. The cone has a 7.7500-inch bore (196.85 mm) and a 0.9062-inch inner ring width (23.017 mm). The complete bearing set measures 7.7500 × 9.5000 × 0.9375 inches (d × D × T).

Heavy-Duty Performance

The tapered roller design provides effective load distribution and reliable support under combined loads. The separable cone and cup structure makes installation and replacement more convenient. The complete LL639249/LL639210 set has a dynamic load rating of approximately 160 kN and a static load rating of 330 kN, according to NTN specifications. It is suitable for heavy-duty transmissions, industrial machinery, and large equipment.

Inch Series Replacement Market

LL639249 belongs to the LL639200 bearing series. Its inch dimensions make it relevant to customers maintaining imported machinery and equipment designed around imperial bearing standards. The matching cup number is LL639210. Distributors can offer the cone and cup as individual components or as a complete bearing set. Confirming both part numbers helps avoid mismatched components.

Product Sourcing and Order Coordination

For replacement inquiries, customers should check the cone number, cup number, total width, and mounting requirements. We can assist with comparing original part numbers and technical drawings. This is particularly useful for distributors handling large industrial bearings and less common inch-series models. OEM packaging and bulk packing can also be discussed according to purchasing requirements.
