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 spring clip, 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:

• Spring Clip (Standard): Quick and easy installation, ideal for most applications, recommended for chain sizes #25 through #50
• Cotter Pin: More secure than spring clips, available for all sizes, recommended for higher-load applications
• Riveted: Permanent installation for maximum strength, available for all sizes, 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
• Install with closed end of spring clip facing direction of chain travel
• Inspect spring clips regularly and replace if damaged or loose
• For cotter pin style, ensure pins are properly spread after installation
• Consider using offset link if odd number of chain links is required

Common Applications:

• Heavy-duty conveyors and material handling equipment
• Agricultural equipment requiring maximum strength
• Industrial drives and transmissions with high loads
• Any application requiring periodic chain removal for maintenance
