Overview
The Falk 1020G exposed bolt sleeve (0744992) is a LifelignĀ® flanged coupling component designed by Rexnord for reliable gear coupling assemblies in industrial power transmission applications. This sleeve accommodates the 1020G coupling size and features exposed bolt construction for straightforward installation and maintenance in production environments requiring high torque delivery and rotational precision.
Key Features
- Exposed bolt design enables one-wrench tightening with reduced head cap screws and non-turning locknut
- Triple-crowned tooth geometry minimizes tip-loading, backlash, and wear caused by shaft misalignment
- Steel construction with gasket included for sealed operation
- AGMA bolt pattern ensures interchangeability with standard gear couplings on retrofit applications
- Lubrication plug locations positioned for effective grease application and maintenance
- Three-year warranty when lubricated with Falk LTG Grease and used with genuine Falk Lifelign components
