Rubber Shock Absorber Pad: Field Notes from the Floor and the Test Lab

If you’ve ever stood beside a generator skittering across a concrete slab, you already know why vibration control matters. I’ve been around factories long enough to say this with a straight face: getting rubber right is half science, half craft. As a rubber parts manufacturer, we obsess over the tiny variables—mix design, cure time, durometer—that turn a simple pad into a quiet, dependable workhorse.

What’s changing in the industry (and why it matters)

Electrification is pushing stricter NVH targets; construction sites are asking for faster installs with fewer anchors; maintenance teams want pads that shrug off oil and UV without cracking in a year. Materials are shifting too—more EPDM for weather, more NBR around hydraulics, and yes, recycled content where performance allows. Honestly, the winners are the teams balancing sustainability with hard data.

How we make it (short version)

- Compounding: polymer + carbon black/silica + oils + curatives, mixed to target durometer and damping.
- Molding: compression or transfer molding; vulcanization curve tuned to avoid under/over-cure.
- Finishing: deflashing, optional adhesive backing, metal-shim bonding, surface texturing.
- Testing: hardness (ISO 7619-1), tensile/elongation (ISO 37), compression set (ISO 815-1), aging (ASTM D573), salt spray for inserts (ASTM B117). Typical service life ≈ 5–8 years depending on load, temperature, and oils.

Where it’s used

HVAC bases, generators, compressors, CNC feet, pumps, packaging lines, vehicle lifts, rail cabinets, even under home treadmills (no shame in that). Many customers say the install takes minutes and the difference is immediate.

Advantages with data

In our lab (60 Shore A NR, 20 mm thick, 180 kg load), we measured transmissibility T ≈ 0.28 at 25 Hz, and a damping ratio ζ ≈ 0.12. Compression set came in at 18% after 22h @70°C (ISO 815-1). Field teams report noise drops of 10–18 dB around gensets—your mileage, as always, depends on the structure and load path.

Customization tips (from the field)

Outdoor gear? Pick EPDM. Oil on the floor? Go NBR. Highly dynamic loads (presses)? NR with a metal shim. If the machine “walks,” try a waffle texture and a slightly softer pad; surprisingly, 50–60 Shore A often beats 70A for real-world isolation. Our team at rubber parts manufacturer will model load/deflection and send a quick curve.

Case study (quick read)

A concrete batching plant reported cracked grout and operator complaints near a 45 kW compressor. We swapped in 8 pads (20 mm EPDM, 60A) under the skid. Result: floor RMS vibration dropped ≈ 42%, and the nearest workstation measured -12 dB(A). Six months later, no bolt re-tightening. Not bad, I guess.

Made where we can watch every batch: No. 228 North Street, Gaobeidian City, Hebei Province. If you need drawings reviewed, the applications team at rubber parts manufacturer can turn around recommendations within a day, usually.
