🛡️ Structural Advantages & Heavy-Duty Performance

Maintenance-Free Sealed Unit: Pre-lubricated at the factory with wide-temperature agricultural grease, eliminating daily greasing routines while preventing lubricant washout.

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

Extended Inner Ring Stability: The 39.52mm wide inner ring offers maximum shaft contact surface, reducing shaft wear and fretting corrosion under heavy torsional field stress.

Vacuum-Degassed GCr15 Chrome Steel: Manufactured from premium high-carbon chromium steel for high dynamic load capacity and maximum fatigue resistance under severe radial stress.
