Cone 687 / Cup 672, Timken 687/672, 6-Inch Bore Tapered
The 687/672 is the definitive "limit pusher." It represents the absolute maximum inner diameter—a perfect 6.000 inches (152.40mm)—that can be paired safely with the 7.625" (193.67mm) OD 672 cup. Sourcing this exact assembly allows mechanics to utilize the thickest possible driveshaft in their existing housing. It delivers extreme structural rigidity, totally eliminating bending forces in the most aggressively overloaded industrial and mining operations.
