Gear

Choosing the wrong gear coupling can be costly. Fortunately, Falk has designed a solution to save you money: Lifelign gear (G) couplings. With their low initial cost – along with the highest bore capacities and ratings available – Falk G couplings can save you as much as 35 percent over competitor brands.

Built to last longer, protect your equipment and save you money, Lifelign G couplings are ideal for a world of applications. They’re designed to AGMA standards and are interchangeable “half for half” with many other brands. With a wide variety of sizes and capacity ratings available, the durable G coupling gives users the broadest possible choice range – no matter the application or factory environment.

Longer Life

The Lifelign G coupling is built for a longer working life, with Falk’s superior Long Term Grease  lubrication and a four-point seal to extend its lifecycle and reduce maintenance. It comes with a 3-year warranty when Falk Long Term Grease is used.

Equipment Protection

Triple-crowned teeth are designed with crowns on all working portions of the teeth, so they can slide freely to accommodate misalignment and movement. As a result, connected equipment is protected from damaging loads.

Interchangeability

Because of their AGMA standard sizes, Lifelign G couplings are one-half for one-half interchangeable with other standard gear couplings, regardless of the difference in sleeve barrel, hub and bore dimensions.
