Overview
The Falk Rexnord 0729505 is a 1025GL gear coupling sleeve manufactured by Falk, a trusted name in power transmission for over 100 years. This steel sleeve assembly is engineered to provide reliable torque transmission in industrial machinery and power transmission systems. As a modular component of flexible gear couplings, the 1025GL sleeve mates with flex hubs to create a complete coupling assembly capable of accommodating shaft misalignment while transmitting high torque loads.
Key Features
- High Torque Capacity: Rated for 66,150 in-lbs (7,470 Nm) enabling use in demanding applications
- Steel Construction: Durable steel material with internal spur teeth for reliable engagement
- Compact Design: 8-3/8″ outside diameter fits standard 1025GL coupling sizes
- Speed Rated: 3300 RPM maximum operating speed suitable for industrial motors and drive systems
- Flexible Coupling Technology: Accommodates axial, radial, and angular misalignment while protecting connected equipment
Technical Specifications
The 1025GL sleeve assembly provides precise dimensional and performance characteristics for critical power transmission duty.
