Overview
The Falk 1020G sleeve exposed bolt (part number 0744992) is a flanged coupling sleeve component for the Rexnord Falk Lifelign G20 gear coupling series. This sleeve assembly features exposed bolts and is engineered for use in industrial mechanical power transmission applications where shaft misalignment tolerance and high-torque performance are required.
Key Features
- Triple-crowned Lifelign tooth design minimizes wear and articulates freely under misalignment
- Exposed bolt configuration for straightforward assembly and maintenance
- Steel construction rated for operating temperatures from −30°F to +200°F
- Reduced head cap screws and non-turning locknuts allow single-wrench tightening
- AGMA bolt pattern ensures interchangeability with standard gear couplings
- Includes gasket and lubrication plug locations for effective greasing
