Floor Mounted Spring Vibration Isolator with Adjustable Height and Lateral Rubber Damping Spring Shock Absorber
Product Details
25 mm Load Deflection
,Corrosion-Resistant ED Finish
,Low-Frequency Spring Isolator
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.

About This JB Vibration Isolator
Chosen for medium-speed machinery, this JB mount combines a load-bearing spring with end-mounted rubber damping. The arrangement keeps the equipment stable while preventing the spring from amplifying vibration at its natural frequency.
- Bolt-on fixings top and bottom simplify replacement on existing bases.
- Adjustment nuts at the spring head allow fine levelling without extra plates.
- Reinforced nylon keeps the body light, which helps where access is tight.
Quick Q&A
Q: Can it replace an existing spring mount?
A: In most cases yes; share the old mount's load rating and fixing centres and we will match or improve on it.
