Overview
The Rexnord 1110T Steelflex Tapered Grid Coupling (part number 0758254) is a grid coupling replacement element engineered for industrial power transmission applications. Known for durability in critical applications, proven performance and versatile design, these couplings are the most frequently specified grid coupling in North America. The tapered grid design connects motor and driven shafts while absorbing shock, vibration, and minor misalignment.
Key Features
- Tapered T-Grid Profile: Tapered T-Grid profile fits smoothly into hub for easy installation and maintenance.
- High-Strength Material: High-strength alloy steel grids are tempered to spring hardness and precision shot peened for increased fatigue strength, providing reserve strength for longer life or allowing a smaller size coupling to be selected.
- Extended Lubrication Intervals: No need to re-lubricate for 5 years when using Falk Long Term Grease (LTG).
- High-Speed Operation: Operating speeds up to 10,000 RPM, even in high shock and vibratory conditions.
- Replace-in-Place Design: Replace-in-place design eliminates the need to move hubs or re-align shafts, reducing element change out time.
- Durable Sealing: Durable nitrile seals prevent lubricant leaks and entrance of water, dust, or other particles.
Technical Specifications
The 1110T size coupling accommodates various bore configurations when paired with tapered bushings or reborable hubs. Maximum bore capacity reaches 4½” in reborable hub versions. Gap specifications for installation are .188″ for the 1110T size. The coupling operates reliably under normal and shock load conditions, providing flexible accommodation to changing load demands typical in industrial drive systems.
Typical Applications
- Industrial motor-to-driven-equipment transmission
- Pump, blower, and compressor coupling
- General machinery power transmission in manufacturing
- High-speed rotating equipment requiring shock absorption
- Systems requiring minimal maintenance and extended service intervals
- Applications with minor shaft misalignment compensation needs
