🛡️ Structural Advantages & Heavy-Duty Performance

• Relubricable System: Outer ring features integrated grease lubrication holes, allowing routine field maintenance flushing to purge contaminants and significantly extend bearing service life.

• Heavy-Duty Multi-Lip Sealing: High-performance multi-lip contact rubber seals create a solid barrier against moisture, mud, abrasive soil, and fertilizer residue during continuous tilling.

• Extended Inner Ring Support: 44.45mm wide inner ring offers maximum shaft contact surface, reducing shaft wear, fretting corrosion, and deflection under high field torque.

• Vacuum-Degassed GCr15 Chrome Steel: Premium high-carbon chromium steel construction provides excellent fatigue strength and high dynamic load capacity under extreme radial stress.
