China Professional SZ Type Elastic Diaphragm Shaft Coupling Manufacturer
Product Description
Our SZ Type elastic diaphragm shaft coupling with locking device is an excellent choice for those who want a high-quality coupling that is durable and precise. Made with high-quality stainless steel sheet as elastic material, this coupling has high torsional rigidity and is perfect for the rapid response of automatic control transmission. There is no backlash or hysteresis, and high-precision repetitive positioning can be performed with ease. The low inertia design gives full play to its excellent durability for CHINAMFG and reverse running, braking, etc. This is why it is the most suitable coupling for the feed shaft and spindle of CNC machines. Compared with the expansion sleeve connecting elastic diaphragm coupling, our SZ Type coupling has a smaller moment of inertia. Under the same outer diameter, the applicable shaft hole is larger, the assembly, and disassembly are more convenient, and the price is lower.
Advantages
- High-quality steel sheet
- Precision positioning
- More durable
