300‑Series mounted ball bearings are engineered for applications that exceed the limits of traditional 200‑Series designs. Larger rolling elements deliver higher load capacity while maintaining the high‑speed performance ball bearings are known for. This makes the 300‑Series a solid choice for air‑handling, agricultural, and other applications with moderate‑to‑heavy loads at elevated speeds; especially when spherical or tapered roller bearings add unnecessary cost.

With reduced surface contact compared to mounted spherical roller bearings, they generate less friction and heat, helping extend lubrication life and reduce maintenance. Backed by more than 80 years of Dodge® mounted ball bearing expertise, 300‑Series bearings are stocked for immediate delivery and built to keep your equipment running when uptime matters most.
