Overview
The Martin 11SC48 is a Quadra-Flex flexible coupling flange engineered for industrial power transmission systems. This robust cast iron component is part of Martin’s extensive line of flexible couplings designed to connect rotating shafts while accommodating misalignment and reducing vibration transmission between equipment.
Key Features
- Cast Iron Construction: High-strength cast iron provides durability and extended service life in demanding industrial environments
- Flexible Elastomeric Element: Two-piece flange design with elastomeric tire accommodates shaft misalignment and absorbs shock and torsional vibration
- Quick Installation: Two-piece flange design enables rapid assembly and removal without disturbing connected equipment
- Bored-to-Size Options: Available with slip-fit boring on standard shafting, stocked in a wide range of bore sizes
- Proven Reliability: Built to Martin’s manufacturing standards for consistent performance across industrial applications
Technical Specifications
The Martin 11SC48 Quadra-Flex flange is engineered to deliver stable performance in continuous-duty power transmission applications. The coupling accommodates angular misalignment to 4 degrees and parallel misalignment compensation through its elastomeric sleeve element. The two-piece flange design facilitates easy maintenance and installation without full equipment disassembly.
Typical Applications
- Electric motor-to-pump connections
- Conveyor drive systems
- Fan and blower installations
- Compressor and pump drives
- General industrial machinery power transmission
- Equipment requiring vibration isolation
Compatibility & Replacements
Compatible With
- Quadra-Flex elastomeric sleeve elements and spider inserts
- Martin standard shaft bores and keyways
- Electric motors, engines, and prime movers
- Industrial pump and compressor applications
- Standard metric and imperial bearing systems
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The Martin 11SC48 may replace similar-sized Quadra-Flex coupling flanges, but specific model interchangeability requires confirmation based on your application’s bore, torque rating, and misalignment requirements.
Works With
- Martin Quadra-Flex elastomeric sleeves (multiple compound options: TPR, EPDM, Neoprene, Hytrel)
