Features

• Provide for load capacity requirements in smaller space than coiled spring types.
• Provide locking of screws and can suppress abnormal sound, looseness and unsteadiness by pressurizing retained parts at specific levels.
• Absorption of vibrations where dynamic load is applied.
• For Curved and Dish Springs, different spring characteristics can be obtained by combining (stacking) them in the same direction and/or in the face to-face direction.

Dimension

• Material = Carbon spring steel
• Hardness = 40 through 50HRC
• Finish = Phosphate coating (ACP)
• Notes:
  1. The value d is the diameter of inscribed circle. The value D is the diameter of circumscribed circle.
  2. The value H is a dimension when three threads are flush with each other with parallel two planes compressed (see Fig. 1).
