DF Type Heavy Duty
Face Seals
The DF heavy-duty duo cone seal consists of two diamond-shaped elastomer rings and a pair of metal rings. The metal ring’s contact surface with the rubber ring is L-shaped, which plays a crucial role in stabilizing the seal within its seat cavity. During operation, the torque generated by the elastomers provides the necessary transmission force, ensuring the face seal’s reliable performance and operational stability.

Application and Design Features
The L-shaped duo cone seal is primarily designed for heavy-duty equipment, commonly found in mining machinery prone to significant vibration and impact. It is typically used in mining equipment, screw conveyors, sprockets, and crop harvesters. This type of seal includes two L-shaped metal rings and two trapozoid elastomer rings, which are assembled within the L-shaped seal housing.
Similar to the DO-type seal, the DF type duo cone seal operates by utilizing the torque generated by the elastomer rings to stabilize its position within the seal housing. The diamond shaped elastomers, with greater deformation capacity compared to the regular O-rings, provide a larger floating range, which enhances the seal’s adaptability to varying operating conditions.
Moreover, the L-shaped design enables easier assembling and processing of the housing making it a practical choice for applications requiring robust sealing solutions in heavy-duty environments.
DF Type vs. DO Type: Installation and Design Considerations
The DF-type design offers advantages over the DO type, requiring less installation space and featuring groove shapes that are easier to process. However, precision in groove processing is crucial due to higher accuracy requirements for accommodating this series of seals.
Differences in compression deformation between DF-type and DO-type rubber rings necessitate strict adherence to specified compression sizes and clearances during installation.
At Decent Machinery, we not only deliver high-quality face seals but also specialize in tailored solutions designed to meet specific requirements such as cost considerations, material compatibility, operational environment, temperature constraints, and maintenance needs.
