Overview
The Falk 1025G10 gear coupling sleeve is a precision-engineered component designed for reliable power transmission between rotating shafts in industrial automation and heavy equipment applications. Falk 1025G10 sleeves accommodate inherent misalignment while maintaining high torque capacity and durability. Built with steel construction and flanged design, this sleeve integrates seamlessly into 1025G series coupling assemblies used in mixers, crushers, pumps, fans, and material handling systems.
Key Features
- Steel construction with flanged sleeve design for secure assembly
- Accommodates angular and radial misalignment without compromising performance
- Triple-crowned teeth for extended contact surface and improved load distribution
- Four-point seal design extends coupling life and reduces maintenance intervals
- Compatible with Falk Long Term Grease (LTG) for up to three years between relubrication
- Grade 8 fasteners included for added structural strength
