LEF213-2F 4-Bolt Flange Bearing, Eccentric Lock, Double 2F Mud-Proof Seals

1. Product Overview

LEF213-2F four-bolt square cast iron flange bearing unit, matched with YEL213-2F double extended inner ring eccentric lock insert bearing. Double-sided 2F composite seal adopts metal flinger + NBR lip two-stage barrier to block mud, crop debris and cooling water splashes. Eccentric locking collar tightly clamps double extended inner ring for stable single-direction rotation under long heavy vibration. Spherical outer ring offers ±2.5° self-alignment to compensate shaft assembly misalignment. Side grease nipple supports periodic supplementary lubrication. Widely used for large grain harvesters, heavy belt conveyors, grain sorting equipment and textile heavy transmission rollers.

2. Key Advantages

• Dual 2F anti-fouling sealing system: Outer metal flinger throws mud clumps via centrifugal force; inner rubber lip blocks fine dust and water mist, far better anti-mud performance than single 2S rubber seals.
• Eccentric collar delivers uniform full-circle clamping force, anti-loose under continuous vibration, no scratch on shaft surface, ideal for fixed single rotation equipment.
• HT200 grey cast iron square flange housing, high structural rigidity, quick bolt mounting & disassembly, compact size saves equipment layout space.
• ±2.5° self-aligning spherical outer ring eliminates assembly offset stress, reduces abnormal bearing wear and running noise.
• Reserved grease fitting for regular lubrication, extend service life and cut equipment maintenance downtime.
• GCr15 fully heat-treated bearing steel, stable heavy radial load capacity, excellent wear & impact resistance for long-hour heavy-duty operation.
• Standard unified metric dimensions, fully interchangeable with single-seal LEF213 for direct mud-proof sealing upgrade.

Reduce maintenance workload and guarantee stable operation of heavy agricultural & industrial machinery
