Overview
The Falk 1025G10 coupling sleeve is a precision-engineered gear coupling component manufactured by Rexnord for industrial automation and mechanical power transmission. This steel sleeve assembly is designed to connect rotating shafts while accommodating minor misalignment and transmitting high torque loads with minimal backlash.
Key Features
- Steel construction for durability and long service life
- Lubrication ports for easy maintenance with Falk Long Term Grease (LTG)
- Triple-crowned gear teeth for superior load distribution and extended wear life
- Interchangeable with other standard AGMA gear coupling brands
- Accommodates angular and parallel shaft misalignment
- No periodic maintenance required when lubricated with Falk LTG at installation
