Overview
Falk 1020G exposed bolt sleeve 0744992 is a flanged coupling sleeve assembly designed for use with Falk Lifelign Type G20 gear couplings. Manufactured from steel with a 7-inch outside diameter and 12-inch overall length, this component features exposed bolt design with reduced head cap screws and non-turning locknuts for single-wrench installation. Rexnord Falk Lifelign gear couplings are engineered with triple-crowned teeth, allowing the coupling to articulate freely and minimize wear caused by misalignment.
Key Features
- Reduced head cap screws and non-turning locknut allow one-wrench tightening
- Exposed bolt sleeve design with lubrication plug locations for effective grease application
- AGMA bolt pattern makes Falk Lifelign couplings easily interchangeable with any standard gear coupling
- Steel construction for durability in high-speed and high-torque applications
- Three-year warranty on Falk Lifelign couplings when lubricated with Falk LTG Grease and used with other genuine Falk Lifelign components
