No Lubrication Required: The chain does not require additional lubrication, preventing the spread of lubricating oil and reducing maintenance needs.
Cost Saving: Eliminates the cost associated with purchasing lubricating oil.
Productivity Improvement: Maintenance-free operation enhances productivity.

Technical Specifications

Effective for Pitch Elongation: The chain features lubrication between the pin with an oil groove and the bush with a special seal, preventing pitch elongation due to wear.

Features of Oil Sealed Chain Point １ What is Oil Sealed Chain? Due to lubrication between pin with oil groove & bush with special seal, no additional bush link plate lubrication is required and it is effective for pitch elongation occurred by worn out pin and bush. Multiple combinations of sealing materials are installed between bush link plate and pin link plate. The assembled seals contribute to the oil sealed in the gap between pin and bush and prevents the ingress of dust and other contaminants from the outside. In addition, they are designed to follow the axial chain movement of the pin....
