Custom Rubber Spring Solutions
A rubber spring is a rubber buffer molded with a ribbed, coil-like profile instead of a smooth or tapered body. The ribbed shape is what sets it apart from our other buffer styles: each rib compresses in sequence, giving it a longer, more progressive compression travel than a solid buffer — closer to the smooth curve of a coil spring, without the corrosion, lubrication, or resonance issues that come with steel.
At Flexiparts, every rubber spring is custom-molded to your drawing — we build the rib profile, rib count, and durometer around your target load-deflection curve, not pull it from a stock range.
Custom Options at a Glance：
| Attribute | Customization |
|---|---|
| Geometry | Custom shape selection: conical, cylindrical, tapered |
| Load curve | Custom-matched to your existing spring rate |
| Compound | Custom selection for temperature/environment |
| Mounting | Custom: bonded, threaded, or bolt-through |
Typical Use Cases：
Applications currently using metal coil springs where corrosion resistance, built-in damping, or electrical insulation is needed instead.
Why Manufacture With Flexiparts：
Engineering review to match geometry to your existing spring rate, prototype and compression testing before production.
See Conical Buffer, Cylinder Rubber, and Tapered Buffer for shape-specific customization options.
FAQ About Custom Rubber Spring
1. What rubber material do you use?
We select the compound based on what your part will face in service — oil exposure, temperature swings, outdoor UV, that kind of thing. Tell us the operating environment and we’ll spec the material and durometer for it, not the other way around.
2. What’s the difference between a rubber spring and your other rubber buffers?
Shape and travel. Tapered and waisted buffers are solid-bodied and built for shorter, harder-stopping compression. The ribbed profile on a rubber spring lets each rib compress in sequence — we tune that profile to give you a longer, more gradual compression curve, closer to what a coil spring feels like.
3. How much compression travel can it handle?
There’s no fixed figure — travel is a function of the rib count, rib height, and durometer we mold in for your part. Send your stroke requirement and we’ll engineer the geometry around it.
