Kinetic Shock Absorption
To stop lock bumping without altering master key bittings, high-security cylinders embed a floating steel dampening ball in the floor of the keyway.
Dampening Mechanics
- Floating Ball: A spring-loaded $\Phi 2.0 ext{ mm}$ stainless steel ball rests beneath the key tip.
- Impulse Dissipation: When a bump key is struck with a hammer, the spring-loaded ball absorbs and cushions the forward impact, dissipating the kinetic wave before it reaches the pin stacks.
Frequently Asked Engineering & Selection Questions
Q1: How does a floating keyway ball prevent lock bumping?
It acts as a mechanical shock absorber at the tip of the key, cushioning the hammer blow and stopping kinetic energy from bouncing the pins.
