LE 309 2F Severe-Service Insert Ball Bearing 45x100x57.0mm Reinforced Design 2F Seal Agricultural

The LE 309 2F is an extra heavy-duty insert ball bearing purpose-built for severe agricultural service. With a 45mm bore and an oversized 100mm outer diameter — substantially larger than standard bearings in the same shaft class — it delivers an exceptional 52.7 kN kN dynamic load rating for the most demanding rotating equipment.

The maximized cross-section, reinforced inner ring (57.0mm width), and premium sealing system are engineered for continuous operation under combined high radial loads, shock impacts, and aggressive environmental contamination that would destroy standard bearings within a single season.

Specified by equipment OEMs and maintenance professionals for critical driveline and processing applications where bearing failure means costly downtime.

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.
