Heavy-Duty Box-Type Cassette Oil Seal

This integrated Cassette Oil Seal combines multiple core functions in one compact unit, including high-performance sealing lips, a multi-channel labyrinth dustproof structure, and long-lasting lubricating grease—all engineered to deliver reliable performance for axles and drive shafts of construction machinery, agricultural equipment, and commercial vehicles. Its spring-loaded sealing lip design effectively compensates for shaft runout and eccentricity during operation, while the multi-layer labyrinth structure forms a strong barrier against external contaminants like mud, water, and dust, preventing premature wear of internal components.

Notably, this seal eliminates the need for additional shaft hardening or precision grinding processes, simplifying pre-installation preparation and reducing overall processing costs. It also minimizes the number of components requiring management during storage and assembly, lowering the risk of accidental damage. Even in harsh working environments such as construction sites, farmlands, or rough road conditions, it consistently maintains excellent sealing performance, significantly extending the service life of the equipment it protects and cutting down on frequent maintenance expenses.
