M12 Natural Rubber Silent Block Shock Absorber For Air Compressor
Product Details
M8 rubber shock absorber for ac
,M10 natural rubber vibration isolator
,M12 silent block shock absorber
JNHQ shock absorbers can achieve a high degree of shock absorption in axial pressure and lateral pressure, especially in generators, engines and systems. The shock absorption effect is very good, and the application range is about 25Hz (1,500rpm). It is suitable for motors with frequency of 1500-3500Hz.
The surface is chrome-plated, anti-corrosion and anti-rust, with high thread strength
Oil-resistant and shock-proof rubber layer is used inside, which has strong impact resistance and better shock absorption effect
- Good Performance: This bell shaped shock damper can achieve a high degree of shock absorption effect in axial pressure and lateral pressure.
- Scope of Application: Used in generators, engines and systems, the shock absorption effect is very good.
- Good Shock Absorption Effect: The internal rubber and iron parts are full glued to provide the best shock absorption effect, in addition, safety lock parts are safety.
- Professional Products: The bell shaped shock damper can bear the pressure and shear force at the same time, and the rubber is firmly bonded through vulcanization and the bottom galvanized steel plate.
Rubber mounts are available in a variety of sizes and styles, to suit both heavy duty machinery and lighter weight precision applications.
Different designs of machine foot can be offered, either with or without rebound control and with a variety of fitment/installation configurations.
Some machine feet offer different stiffness characteristics in the three main directions of loading, thus allowing high flexibility to ensure good vibration isolation but minimising movement in other planes.

It designed for use in both static and mobile applications, typically as engine mounts, marine mounts, compressor mounts and genset mounts.
Shanghai Songjiang Jiufu Shock Absorber Co., Ltd. manufactures the silent block shock absorber shown here at its Songjiang District, Shanghai site. The business dates from 2003 and has never diversified away from rubber-to-metal bonded anti-vibration parts, which is why M8, M10 and M12 thread variants can be produced from a common mould family.
Compressor and engine mounts take punishment - oil mist, heat, continuous cycling - so compound choice drives service life more than geometry does. The plant formulates its own stock and tests hardness and deflection on each batch, an approach that supports turnover of one to ten million US dollars with forty to fifty percent of goods exported.
Minimum order quantity starts at 100 pieces, standard items ship in 5 to 8 working days and every enquiry is answered with a priced quotation inside 24 hours. For compressor and engine mounts that quick turnaround matters, because a machine sitting idle waiting for isolators costs more than the parts do. Custom hardness, thread and plating are handled on the same production line.

ISO 9001 certification covers the production quality system. Rubber compounds conform to RoHS and REACH and the supporting declaration can be issued with the shipment. Accredited laboratory reports are obtainable for project orders, and internal testing covers hardness, load-deflection, oil resistance and heat ageing throughout production rather than only at the end.
Send the compressor or engine mass, hole spacing and thread size - the plant will confirm compound and dimensions before quoting.
The complete certification pack for this plant is shown below: three ISO management system certificates, the RoHS certificate of conformity and an independent laboratory test report.
b. For custom products, sample fee is determined by the detailed sample requirements. Normally, it takes 7-15 days.
1. You can provide 3D drawing to us, then our engineers and production teams evaluate the design and quote you the precise cost.
2. If you don't have 3D drawing, you can provide 2D drawing or draft with features details with full dimensions, we can draft 3D drawing for you with fair charge.
3. You can also customize Logo on the product surface, package, color box or carton.
