Caterpillar 1M-7912 Tapered Roller Bearing Cone

The Caterpillar 1M-7912 is a single tapered roller bearing cone with a 47.63 mm bore (about 1.875 in), designed to pair with the matching 1M-7911 cup in drive rotor assemblies. Crafted from alloy steel for strength and durability, this cone serves as one half of a two-piece bearing set used in a range of Caterpillar heavy equipment drive trains. Typical applications reference prominent Cat machine families and D-series tractors, including 561C, 583T, 587R, 587T, 951B, 955C, 955H, 955K, 977D, and D5, D6C, D8N, D8R, D8R II, D8T, as well as PL83 and PM-201/PM-465B configurations. To complete the bearing assembly, use it in conjunction with the 1M-7911 cup. This cone supports precise shaft alignment and efficient load distribution, contributing to reliable rotational performance in demanding off-road, mining, and heavy-duty construction equipment scenarios.
