CY series super nut

Product catalog summary

Overview: The document provides technical specifications and guidelines for the CY series Super Nut, a hydraulic bolting solution suitable for high-strength machine tightening, particularly in large hexagonal nuts used in gears, crushing machines, military machines, etc.

Specifications:

Operating Temperature: -60 to 200 degrees Celsius.
Bolt Stress: 410-890 MPa under standard load.
Suitable for high-strength applications and large hexagonal nuts.

Model Specifications: The document includes a detailed table listing various models of the CY series Super Nut, specifying bolt size, nut dimensions, tightening force, torque, and weight. Key parameters include:

Outside Diameter (D), Thickness (T), Center Distance (C), Length (L), Number of Push Bolts (n), Diameter (J), Across Flats (A/F), Outside Diameter of Gasket (Dw), Thickness of Gasket (t), Tightening Force (KN), Torque (Nm), and Weight (Kg).

Recommended Bolt Tightening Force: A chart is provided for recommended bolt tightening forces, suitable for bolt tensioners and hydraulic nuts, based on different strength grades (4.8 to 12.9) and materials (e.g., general structural steel, chrome molybdenum alloy steel). The chart lists minimum breaking strengths and corresponding tightening forces for various bolt sizes.

Attention: The data in the chart is measured under 60% yield limit of the bolt. The recommended tightening torque is 70-80% of the chart data. For example, for an M42 grade 10.8 bolt, the tightening torque is calculated as 423.5-484 KN.
