Rigid coupling, strong torsional rigidity, no rotational clearance under load, rigid transmission of torque. Suitable for occasions where the two shafts need high centering accuracy and no relative offset.
rigid shaft coupling Detail
| Product Name | rigid shaft coupling |
| Product Material | Medium carbon steel or alloy structural steel such as 45 steel and 40Cr are mostly used, and stainless steel is used in some high-precision scenarios. |
| Product Process | It is formed by forging or cutting from bars, then turned, milled, drilled, etc., and finally assembled and inspected. |
| Surface Treatment | Usually black, zinc or chrome plating |
| Application | Suitable for machine tools, servo motors, pumps and automation equipment. |

How to choose the corresponding model of rigid coupling for equipment with different shaft diameters?
You need to provide the diameter, speed and installation space of the two shafts. We will match the inner hole size according to the shaft diameter range and recommend the corresponding specifications based on the working conditions.
How much torque can the rigid coupling withstand? Will it break under heavy load?
Different models have different torque tolerance ranges. When selecting, you need to match the actual load. Under compliant use, it can withstand a short-term impact of 1.5 times the rated torque without breaking.
What is the approximate service life of the product? What maintenance is required on a daily basis?
Under normal working conditions, the service life is more than 5 years. You only need to regularly check the tightness of the connecting bolts and keep the surface clean. No complicated maintenance is required.
