Combine harvesters operate under extreme mechanical conditions—variable torque, crop dust, vibration, and oil temperature fluctuations. Gearboxes in these machines require advanced sealing to prevent oil leaks and maintain torque efficiency. COMBI radial shaft seals are specifically designed to meet these agricultural challenges.

These seals integrate oil and dirt lips into a single compact unit, delivering maximum sealing power with minimal space requirements. Their robust materials resist breakdown from bio-oils, synthetic lubricants, and external contaminants like husks and grit.

COMBI seals for harvesters also withstand shock loads and shaft deflections during field turns and heavy loads. Their flexible lips ensure a continuous seal even during misalignment or gear shifts.

Maintenance crews appreciate how COMBI seals extend gearbox service intervals, minimize lubricant top-offs, and reduce emergency repairs in peak harvest season. These benefits directly support operational uptime and yield efficiency.

For farmers and agri-equipment OEMs, investing in quality sealing like COMBI translates to smoother operations and fewer in-field failures.
