Overview
The Falk 1070T10 grid coupling is a double-flexing, close-coupled grid coupling designed for reliable power transmission in four-bearing motor/driven equipment systems. Manufactured by Rexnord (Falk Steelflex), this T10 series coupling features a horizontally-split aluminum cover with an integrated grid assembly, allowing field replacement of grids without moving connected shafts or equipment.
Key Features
- Horizontally-split design – Grid replacement without disconnecting shafts
- Double-flexing capability – Accommodates parallel, angular, and axial misalignment
- Aluminum cover construction – Lightweight with excellent corrosion resistance
- Close-coupled configuration – Minimal shaft spacing for compact motor/pump installations
- High torque rating – 8,800 in-lb (994 Nm) for robust industrial duty
- Grease-lubricated – Compatible with Falk Long Term Grease (LTG) for extended service intervals
