LE 314 2F Reinforced Heavy-Duty Insert Ball Bearing 70X150mm Spherical Outer Surface for Demanding Ag Use

The LE 314 2F is a reinforced heavy-duty insert ball bearing designed for the most demanding positions in large agricultural equipment. With a 70mm bore, an enlarged 150mm OD, and a 78.0mm inner ring, it achieves an impressive 104 kN kN dynamic load rating — significantly exceeding standard large-bore bearings.

The reinforced cross-section and premium internal geometry are engineered for applications where bearing loads fluctuate between heavy static loading during transport and high dynamic forces during field operation. The 2F seal system with heavy-duty flinger provides uncompromising contamination protection.

Selected by professional equipment engineers for critical bearing positions where standard bearings have proven inadequate under intensive agricultural use.

Q1: Can you provide custom bearings?
Yes, we support OEM and custom production based on your drawings, samples, or technical requirements.

Q2: What is the delivery time?
Standard models: 7–15 working days. Custom products: depending on specifications and order quantity.

Q3: Do you provide samples?
Yes, sample orders are welcome for quality evaluation before bulk purchase.

Q4: What is the difference between 2F and 2F.SH?
2F is the standard version suitable for operating temperatures -20°C to +100°C. 2F.SH is the heat-stabilized version for applications up to +150°C.
