How are springs rated?
Firstly, springs are tested by cyclic compression in a hydraulic press to maximum compression.
Maximum compression is approximately 50mm. After several hours of successful testing, the spring is then rated.
- 4 Leaf 550kg
- 4 Leaf 550kg – Galvanised
- 5 Leaf 650kg – Galvanised
Center pinned means the centre bolt locates at the centre of the spring.
Sorry, there are no springs with extra leaves in the short shackle range.
Why some springs break prematurely or lose spring tension? Read about vibration fatigue here.
