FAQ's of SIT Couplings & Locking Devices:
Q: How do SIT Couplings & Locking Devices accommodate misalignment during operation?
A: SIT Couplings & Locking Devices are designed with a flexible structure that compensates for angular, axial, and radial misalignments. This flexibility reduces vibration and mechanical stress on connected shafts, promoting smooth power transmission and prolonging equipment life.
Q: What are the main applications for SIT Couplings & Locking Devices?
A: These devices are primarily used for shaft connection and power transmission in industrial machinery, where precise alignment and high torque capabilities are critical. Their design makes them ideal for various industries including manufacturing, automation, and material handling.
Q: When should I choose a flange mounting type over a set screw for installation?
A: Flange mounting is recommended for applications needing stronger, more robust shaft connections and easier alignment, especially with larger diameters. Set screw mounting is suitable for smaller shafts and less demanding installations, providing a compact and straightforward setup.
Q: Where are SIT Couplings & Locking Devices manufactured and exported from?
A: SIT Couplings & Locking Devices are manufactured in Italy and distributed, exported, and supplied globally through an extensive network of distributors and traders, ensuring reliable access to various industries worldwide.
Q: What process is involved in customizing the bore size or outside diameter?
A: Customizations are made according to customer specifications, with precision engineering to match the required bore size (20 mm to 120 mm) or outside diameter (up to 250 mm). This ensures optimal fit and compatibility with diverse machine shafts and applications.
Q: What are the benefits of SIT's zero-backlash design?
A: Zero-backlash design eliminates play between connected shafts, ensuring accurate torque transmission, reducing wear and tear, and improving the response of machinery in high-precision and dynamic applications.
Q: How do I maintain SIT Couplings & Locking Devices for optimal performance?
A: Regular maintenance includes periodic inspection for wear, checking and replenishing lubrication (grease or oil as recommended), and verifying mounting integrity. Following SIT's guidelines ensures continued high performance and extends the service life of the couplings.
