- Available with cotter pin or riveted attachment
- Heat-treated components for maximum strength and durability
- Precision manufactured for proper fit and smooth operation
- Enables quick chain assembly and disassembly
- Sold individually
ANSI Specifications:
- Chain Size: 100H-1 Heavy Duty
- Pitch (P): 1.250″
- Roller Width (W): 0.750″
- Pin Diameter: 0.375″
- Plate Thickness: Heavier than standard 100 for increased strength
What is a Connector Link?
A connector link (also called a master link or connecting link) is a special removable link used to join the two ends of a roller chain loop. Unlike standard chain links that are permanently assembled, connector links feature a removable side plate secured with either a cotter pin or rivet. This design allows you to connect and disconnect chain without special tools, making installation, maintenance, and repairs much easier.
Attachment Options:
- Cotter Pin (Recommended): Secure attachment for high-load applications, pins must be properly spread after installation
- Riveted: Permanent installation for maximum strength, use when connector link will not need removal
Installation Notes:
- Connector links are slightly weaker than standard links – position away from high-stress areas when possible
- For cotter pin style, ensure pins are properly spread after installation
- Inspect cotter pins regularly and replace if damaged or loose
- Consider using offset link if odd number of chain links is required
Common Applications:
- Heavy-duty agricultural equipment and machinery
- High-load conveyors and material handling systems
- Industrial drives requiring increased strength over standard chain
- Any application requiring periodic chain removal for maintenance
