OvOn™ Bidirectional Live-Loading Disc Springs
型号
Internationally patented live-loading disc spring that works both ways: it can go downward to absorb a sudden pressure surge or temperature increase, and upward to compensate bolt relaxation, where conventional disc springs, stretching nuts and stretching bolts compensate upward only. Each spring is designed twice, with a first stage that reaches the standard bolt load required and a second stage that edges toward bolt yield strength. Made as 17-7PH for ordinary stainless steel or grade 4.6 bolts and H-13 for grade 8.8, A193-B7 or SAE 8 bolts, and both can be nickel plated against chloride-ion corrosion.
- Applications
- Ordinary stainless steel bolts or grade 4.6 bolts
- Temperature range
- -200 ~ 330°C
- Sizes
- M10 (3/8") to M76 (3")
- Design points
- Inflection point A: from one foot standing to two feet standing, OvOn™ reaches standard bolt load required; max point B: from two feet standing to total flat, OvOn™ edges toward bolt yield strength
- Surface treatment
- Oxidation for corrosion prevention
- Nickel plating
- Both models can be nickel plated against chloride-ion corrosion in chemical environment
