Practical answers for vibration-isolation selection

Start with machine weight, number and position of mounting points, operating speed or frequency, direction of movement, expected shock or impact, and the installation environment. The load on each mount—not only total machine weight—should be considered.

Machines rarely distribute weight equally. Motors, gearboxes, tooling and material feed can place more load on one side. Centre of gravity and the actual reaction at each mounting point help prevent uneven compression and unstable installation.

Static equipment mainly needs stable support and isolation. Dynamic equipment adds cyclic forces and operating frequencies. Mobile or impact-driven equipment may need restraint, higher shock capacity or a design that controls movement in more than one direction.

Compression mounts carry load through vertical compression and are common for many machines. Shear designs can provide greater flexibility for a given size. Some products combine both behaviours; the correct choice depends on load direction, movement and available space.

No. Some installations use free-standing or levelling mounts, while high-impact, tall or safety-critical machines may need positive fixing or a prepared foundation. The machine manufacturer’s installation requirements should always be checked.

Available clearance, machine alignment, service access, centre of gravity and allowable movement all matter. Thread size, bolt projection, base footprint and levelling range should be confirmed before ordering.

Tell us about oil, coolant, outdoor weather, ozone, heat, chemicals, wash-down, dust or food and pharmaceutical hygiene requirements. These conditions affect rubber compound, metal finish and protective treatment.

No. Isolation performance depends on the relationship between forcing frequency and the supported system’s natural frequency. Pipe strain, rigid connections, structural resonance, imbalance or a weak floor can also transmit vibration and may need separate correction.

Share clear photographs, overall dimensions, hole or thread details, equipment data and the old part if available. A drawing or sample helps us compare envelope, load path and fixing before suggesting a replacement.

Machine make and model, total weight, number of mounts, operating speed, mounting layout, existing mount details, environment, desired outcome and clear photographs. A base drawing is especially useful for custom or retrofit work.

Yes, subject to technical review, tooling feasibility, quantity and validation requirements. Provide a drawing, sample, material expectations, load or movement conditions and the intended service environment.

Inspect during routine machine maintenance and after abnormal impact, relocation or alignment work. Look for cracking, permanent compression, separation, corrosion, loose fasteners, oil attack and contact between parts that should remain isolated.

Vibration isolation reduces the transmission of dynamic force between a machine and its supporting structure, or protects equipment from vibration entering through the structure. The isolator must be selected as part of the complete supported system.

Shore hardness indicates indentation resistance, while tensile strength and elongation describe behaviour under a controlled tensile test. They help characterise a compound but do not alone predict finished-mount stiffness, life or isolation performance.

They describe different directions or modes of rubber loading and movement. A design suitable in compression may not be appropriate for tension or rebound restraint. State the expected movement direction, amplitude and shock condition.

They determine whether the product fits the machine base and transfers load correctly. Provide hole count and diameter, pitch-circle diameter where applicable, bolt or thread details, available height and the mounting orientation.

Unless otherwise agreed in writing, the standard warranty is six months from dispatch for manufacturing defects. Warranty duration is not the same as service life. Rubber and rubber-to-metal products should preferably be installed within approximately 3–6 months after dispatch and stored appropriately. Application-specific performance or service-life warranty requires evaluation and written agreement.

Yes, subject to drawing review, process feasibility, tooling, inspection and commercial agreement. Clearly identify controlled dimensions, material expectations, revision status, annual or batch quantity and required customer approvals.
