THE CONNECTING LINKS

• Outer link to be riveted

This link is composed of 2 riveted pins on an outer plate. The other plate is fitted by force on the pins which extremities are riveted after assembly of the plate.

• Spring clip connecting link

2 pins are riveted on an outer plate. The loose plate is maintained by a special spring clip. The unopened part of the spring clip must be oriented in the rotation way of the chain. For BS chains, these links are supplied with Delta® pins for a better resistance to wear.

• Cottered connecting link

Used from 1” pitch (25,4mm) for Delta® chains and from 1.1/4” pitch (31.75mm) in Alpha Premium version. It can be “loose-fit” or “press-fit” type for type B chains.

• Connecting link with self-locking nuts

The pins’ extremities are threaded to fit a self-locking nut. The play on the loose plate is suppressed by the pin conic ambit (SEDIS specificity).

THE CRANKED LINKS

• Single cranked cottered link

Used to obtain a chain with an odd number of pitches from ½” (12.7mm) pitch. These links have removable pins.

• Single cranked link self-locking nuts

Used to obtain a chain with an odd number of pitches. The play on the loose plate is suppressed by the pin conic ambit. The assembly is more reliable than the 216 crank link.

• Double cranked link

Used to obtain a chain with an odd number of pitches. It is composed of an inner link and a cranked link linked by a riveted pin. For BS chains, these links are supplied with Delta® pins for a better resistance to wear.
