LE 306 2F Reinforced Cross-Section Insert Bearing 30mm Shaft 72mm Housing Heavy Farm Duty

The LE 306 2F is a heavy-duty insert ball bearing built with an enlarged 72mm outer diameter cross-section for demanding agricultural applications. While sharing the 30mm bore with standard-duty models, its reinforced housing interface delivers significantly higher load capacity — 28.1 kN kN dynamic rating.

Designed for equipment that subjects bearings to higher radial and impact loads, such as heavy tillage tools, large-diameter rollers, and high-throughput conveyors in grain handling systems.

The robust construction paired with the 2F seal with flinger makes this bearing ideal for the toughest field conditions where standard bearings would fail prematurely.

• Heavy-duty disc harrows and chisel plows
• Large-diameter grain auger support rollers
• High-capacity conveyor head and tail pulleys
• Rotary cutters and flail mowers
• Manure spreader beaters and agitators
• Industrial agricultural processing equipment

Suitable for high radial loads, moderate to heavy impact, and harsh dusty or wet conditions.

• Reinforced 72mm OD cross-section delivers 28.1 kN kN dynamic load — outperforms standard bearings in the same shaft size
• Wider 43.0mm inner ring distributes load over a larger shaft contact area, reducing wear
• Spherical outer surface handles ±2° misalignment in heavy welded structures
• Eccentric locking collar with deeper groove provides positive locking under shock loads
• 2F double-lip seal with flinger repels heavy dust, mud splatter, and pressurized water washdown
• Through-hardened Gcr15 steel withstands impact loading without brinelling
• Factory-filled with high-temperature lithium complex grease for extended service intervals
• Available in standard (2F) and heat-stabilized (2F.SH) variants for high-temperature use

Built for the hardest-working equipment on the farm — where downtime is not an option.

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.
