How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Standard DIN chain connector | The flat sawtooth design offers better engagement and wear resistance in mining applications but may not be interchangeable with standard DIN parts |
| Spiral toothed connector | The flat arc tooth provides more consistent contact and easier installation, while spiral teeth may offer higher engagement force in specific configurations |
| Welded chain link | The connector allows for modular chain assembly and replacement without welding, reducing downtime and field maintenance complexity |
| Cast steel connector | Forged alloy steel offers higher strength and impact resistance compared to cast steel, especially under dynamic loading |
Use Guide
How To Use And Inspect Mining Chain Connectors
- Match the stamped working load limit to the calculated chain load, not the equipment rating
- Ensure the tooth profile engages fully with the mating chain link to prevent slippage
- Inspect the connector for deformation or wear before each use, especially after heavy operation
- Apply the correct torque to any fasteners if the connector includes bolts or pins
- Replace the connector if the tooth is worn flattened or the marking is no longer legible
- Use only with chain types and systems specified in the product documentation

Answers
Mining Chain Connectors FAQ
What is the difference between flat sawtooth and spiral toothed mining connectors?
The flat sawtooth design provides consistent engagement and easier installation, while spiral teeth offer higher engagement force but may require more precise alignment
Can this connector be used on standard conveyor chains?
It is designed specifically for mining ring chains and twin outboard systems. Use only with chains that match the specified tooth profile and size
What safety factor do these connectors have?
A standard 4:1 design factor applies, meaning the minimum breaking load is four times the stated safe working load
Are Material Test Certificates available?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order on request
Can you customise the finish or marking?
Yes. Custom tonnage stamping private label marking and surface finishes including zinc plating powder coating or electrophoretic black are available
How are the connectors packed for export?
Standard carton and pallet packing. We can configure the carton count and pallet pattern to match your warehouse or retail requirements
What standards do these connectors follow?
Manufactured to ISO DIN BS and MT standards with tight tolerances and material selection for mining service conditions
