Overview
The Falk 0744996 is an exposed bolt coupling sleeve engineered by Rexnord for use with Falk Lifelign 1040G gear couplings. This component provides a full-flex connection suitable for demanding industrial applications requiring precision alignment and reliable torque transmission. The sleeve features a flanged design with AGMA-standard bolt holes, making it compatible with any standard gear coupling on existing installations.
Key Features
- Reduced head cap screws with non-turning locknut for one-wrench tightening
- Full-flex design accommodates angular and parallel shaft misalignment
- Steel construction ensures durability in harsh operating environments
- Gasket included for proper assembly and leak prevention
- AGMA bolt pattern ensures interchangeability with standard gear couplings
- Lubrication plug locations designed for effective grease application
