Construction and operating principle

Cable deformation and strand friction work together with elastomer damping to control vibration and shock response.

Applications and selection

Equipment vibration isolation and transport protection. Specify the supported load, mounting direction, available travel and shock environment.

Select HGGN by load direction, travel and shock conditions

All 24 listed models have separate compression, roll and shear ratings. Compression static-load ratings span 62–23,800 N across the catalogue models; this is a family envelope, not one mount’s adjustable range. The initial table shows compression data. Use Columns to view roll and shear values.

1. Confirm the installed direction

Choose the compression, roll or shear table that matches the installation. These HGGN tables do not establish a 45° rating. Combined or angled loading requires application review.

2. Read the ratings together

Check maximum static load and available deflection for that direction. Kv is the catalogue vibration stiffness; Ks is the shock stiffness. Neither is a universal constant for every displacement, and maximum deflection is not the normal static operating point. 1 kN/m equals 1 N/mm.

3. Prepare the application data

Send equipment mass, centre of gravity, mount positions, direction, available travel and installation space. Include excitation frequency and the shock pulse, acceleration and duration where known. A load-only match does not confirm isolation performance.

HGGN selection questions

Should I choose HGGN or HGGS?

Start with the load, required shock travel and mounting direction. HGGN adds elastomer damping and support stiffness to wire-rope isolation; HGGS uses all-metal wire rope. Higher stiffness alone does not mean better vibration isolation. Compare the exact model response and environment.

Can HGGN replace another brand’s isolator?

A similar size or load rating is insufficient. Send the existing part number, drawing, load–deflection data, installation and shock requirements. Interchangeability, bolt pattern and dynamic response require confirmation; no original-brand approval or guaranteed drop-in replacement is claimed.

What temperature can the elastomer withstand, and what about ageing?

The reviewed HGGN tables do not give a verified elastomer grade, temperature range or replacement interval. Provide temperature, oil/chemical exposure, outdoor conditions and service history. Confirm material compatibility and inspection criteria before ordering; do not apply an all-metal isolator’s environmental rating to HGGN.

Can you select it from total equipment weight and the number of mounts?

That is enough to start a review, not to confirm a model. Equal load division only applies to an appropriate symmetric layout with a centred centre of gravity and comparable support conditions. Off-centre loads, torque and shock can load the mounts differently.

Dimensions and curves are available in the linked Chinese PDF; independent CAD files are not currently listed for these 24 models. Do not extrapolate the curves or infer unlisted temperature limits. Final selection requires the actual application and installation review.
