LE 322 2F Extreme-Service Spherical Insert Ball Bearing 110x240x117.0mm for Intensive Industrial Farming

The LE 322 2F represents the pinnacle of insert ball bearing engineering for agricultural and industrial applications. With a massive 110mm bore paired with an imposing 240mm outer diameter and 117.0mm inner ring, it delivers an extraordinary 203 kN kN dynamic load rating — the highest capacity in the insert bearing class.

This bearing is designed for the most extreme rotating equipment in agriculture and related industries: the main shafts of the largest harvesters, industrial-scale grain processing systems, heavy material handling equipment, and specialized agricultural machinery operating at the limits of mechanical engineering.

Every component — from the vacuum-degassed Gcr15 bearing steel to the reinforced cage design and heavy-duty seal system — is specified for maximum reliability under conditions that test the limits of bearing performance.
