Detailed Description

National 14130 is a taper bearing cone engineered for differential pinion use where consistent rolling contact and stable load handling matter. The cone is manufactured from premium-grade steel and uses crowned raceways and rollers to promote even load distribution across the bearing surface. With a 1.3125-inch cone bore, 0.7710-inch cone length, and 0.1400-inch cone radius, this bearing cone is specified for service applications that require accurate dimensional matching. It fits 1953-1956 Ford F-100 front inner, 1953-1956 Ford F-250 front inner, and 1953-1955 Ford F-350 front inner positions. This part cross-references SKF BR14130 for the same application.

What It Helps Address

• Excessive differential pinion bearing wear
• Rough or noisy driveline operation from a worn bearing cone
• Improper bearing surface contact caused by damaged raceways or rollers
• Service replacement needs on classic Ford front inner applications
• Fitment matching for National 14130 differential pinion bearing service

Installation Notes and Tips

Verify cone bore, length, and radius against the original bearing before installation. Clean and inspect the mating surfaces, races, and pinion components for scoring, pitting, or heat damage before assembly. Proper bearing preload and setup are important for differential service, so follow the vehicle service manual for the correct procedure on 1953-1956 Ford F-100, F-250, and F-350 front inner applications.

Quality Assurance

National manufactures this bearing cone with premium-grade steel and crowned raceway geometry to support consistent load distribution in driveline service. National 14130 is built for dimensional accuracy and bearing performance in differential pinion applications.
