Falk Lifelign Gear Couplings
Falk Lifelign gear couplings from the Regal Rexnord portfolio. G20 series for high-torque industrial applications.
About Lifelign gear couplings
Lifelign gear couplings transmit torque through meshed external gear teeth on hub and sleeve halves, lubricated for high torque industrial service. The G20 series is a core Falk family within the Regal Rexnord coupling portfolio for mining, steel, pulp and heavy process industries.
Falk is a Regal Rexnord portfolio brand — not an independent Falk supplier relationship to Golden Bearing Company.
Close-coupled vs spacer
Close-coupled assemblies minimise overall length. Spacer designs provide defined distance between shaft ends for pump and compressor maintenance without relocating the driver.
G20 series overview
G20 designations indicate size and torque class in the Regal Rexnord catalogue. Bore, speed and torque ratings must be verified against published tables for the specific configuration. Designation display for catalogue review typically includes the G20 suffix where applicable.
Compared to Steelflex grid
Gear couplings suit the highest torque and shock loads; grid couplings offer a different maintenance and misalignment profile. See Falk Steelflex for grid-type duty.
Applications
Ball mills, kilns, crushers, marine drives, steel mill stands and heavy industrial gearboxes.

Send manufacturer part numbers, bore sizes or coupling designations for engineering identification and quotation support. This is an identification/interchange enquiry—not a live stock lookup or availability confirmation.
Common questions
Yes. Gear couplings use grease or oil per manufacturer specification. Maintenance intervals depend on speed, temperature and duty.
G20 identifies the Lifelign gear coupling size series within the Rexnord catalogue. Exact designation includes configuration (close-coupled, spacer, etc.).
