Customizable Industrial Floor Mounted Spring Vibration Isolator and Spring Shock Absorber for Vibration Reduction
Product Details
Corrosion-Resistant ED Finish
,Low-Frequency Spring Isolator
,Heat-Treated Anti-Rust Springs
Built to absorb vibration energy and reduce noise in industrial machinery.
The JB adjustable low-frequency damping spring shock absorber has upper bolts for equipment fixing and lower bolts for floor anchoring, so it suits a wide range of installations.
- Aluminum and Steel Construction: High-strength materials ensure durability for heavy-duty service.
- Heat Treated Springs: Specialised heat treatment enhances shock absorption and extends service life.
- Height Adjustment Bolts: Precise levelling and alignment keep installation optimal.
- Lateral Rubber Damping: Improved vertical and horizontal stiffness add stability and safety.
The body is available in reinforced nylon or spheroidal cast iron; nylon offers excellent strength and light weight, while cast iron suits heavier duty.
Screws and screw holes at both upper and lower ends, plus height-adjustment nuts at the spring's upper end, make installation flexible.
Lateral rubber damping at both ends raises the vertical damping coefficient and improves longitudinal and lateral stiffness.
Springs are heat-treated, ED anti-rusted and baked to enhance damping and extend life.
- Load Deflection: 25 mm or 40 mm deflection effectively eliminates mechanical-structure vibration.
- Corrosion Resistance: ED and baking-paint treatment improves oxidation and corrosion resistance.
- Special Rubber Pressure Pads: Rubber pressure pads at both ends raise friction and equipment stability.

Notes on This JB Spring Isolator
This JB unit suits machinery in the low-to-medium speed range, where a steel spring gives deeper deflection than a plain rubber pad. The spring carries the static load while rubber elements at each end provide the damping that stops the spring from ringing.
- Height bolts allow the machine to be levelled after installation, which matters on long pump trains and fan bases.
- Nylon or spheroidal cast-iron bodies let you trade weight against load capacity.
- The anti-rust ED finish resists condensation in plant rooms and basements.
Quick Q&A
Q: Which deflection should I specify?
A: A 25 mm deflection suits most fans and pumps; 40 mm is chosen for lower-speed machines needing deeper isolation.
