Bump Stop Functions in Industrial Air Spring Systems

Function	Explanation	Risks Without It
1. Prevent Structural Impact	Avoids metal-to-metal contact between mounting structures when air spring completely deflates	Deformation of mounting points, bolt shearing, or damage to surrounding equipment
2. Maintain Minimum Safe Height	Supports load after pressure loss, preserving essential clearance for equipment and operation	Sudden drop may snap pneumatic lines or electrical wires, or cause ground contact
3. Limit Over-Extension	Prevents rubber bellows from being over-stretched and torn during rebound conditions	Permanent damage to air spring bellows, rendering it unusable after re-inflation
4. Control Lateral Movement	Provides lateral restraint at travel limit, preventing excessive tilting or misalignment	Equipment may become highly unstable or experience significant misalignment after deflation
5. Provide Failure Warning	Frequent contact indicates insufficient system pressure or chronic leak in air spring system	Problems remain undetected until complete system failure leads to an incident
