COMBI Seal Premium Reinforced Dust-Proof Protection for Rotary Cultivator Axles and Bearings

Rotary cultivator axles work close to soil, roots, sand, and crop residue, so the sealing zone is exposed to continuous abrasive contamination. Once dust reaches the bearing, grease becomes contaminated and axle wear accelerates. This premium reinforced COMBI seal is designed for cultivator hubs, axle ends, and gear-drive positions where a stronger external dust barrier is needed. NBR or HNBR main sealing materials can be selected for lubricant and temperature requirements, while an optional PU dust-deflector lip adds abrasion-focused protection. The reinforced structure helps maintain stable fit under vibration and shock, supporting longer bearing life, lower grease loss, and fewer field repairs. Custom replacement and OEM sizes are available.

Premium Reinforced Dust Contamination Proof COMBI Seal For Rotary Cultivator Axles

Rotary cultivators run directly in the contamination source. Soil and sand attack axle seals continuously, making bearing protection a critical maintenance issue.

Problem Solved

When cultivator bearings fail early, the problem often begins at the axle seal. Stronger dust exclusion helps keep soil out before it damages grease, bearings, and shaft surfaces.
