2. Structural Features
Square bore design (1.5 inches) Standard square bore allows direct mounting on square shafts without keys, ensuring anti-slip, stable drive and easy installation/removal.
Heavy-duty triple-lip sealing ouble-sided triple-lip contact seals effectively block mud, straw, dust and water, providing long-term protection in extremely contaminated environments.
C3 large internal clearance Larger radial clearance prevents bearing seizure under heavy load, high temperature and severe vibration.
Maintenance-free long service lifePre-filled with high-viscosity, water-resistant and anti-wear grease, requiring no regreasing during service life, reducing field maintenance cost.
Heavy load capacity Deep groove ball design supports radial and bidirectional axial loads with high shock and misalignment resistance and smooth running.
3. Typical Applications
Disc harrows, combined tillage machines
Disc shafts and ground wheels of planters and cultivators
Agricultural machinery working under high dust, heavy load and strong vibration
