Vibration / Isolation and Shock Absorption Mounts

Vibration / Isolation and Shock Absorption Mounts, also called rubber buffers, vibration dampers or rubber dampers are designed to prevent damage from strong vibration by absorbing kinetic energy and muffling or reducing noise. They are commonly used as end-stop buffers in transportation and automation and as buffers for elastically-bearing motors, pumps, and compressors.

Sanshi are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

• High quality, economically priced components also known as shock absorbing mounts, vibration mounts, anti-vibration mounts, vibration bobbins, rubber buffers, or rubber bumpers
• Inch and metric sizes
• Tapped and stud types
• Cylindrical and conical, styles to accommodate nearly every application
• Natural rubber with steel and stainless steel components

Materials used for vibration mounts

Vibration mounts are always made of an elastomer element. It is made from either natural rubber (NR), acrylonitrile-butadiene rubber (NBR) or from temperature-resistant and hygienically advantageous silicone rubber. The elastomer element is connected either on one side or on both sides by a retaining washer or threaded bushings and threaded bolts with cover plate. The elastomer elements and metal parts are firmly vulcanized together.

The retaining washers, threaded bushings and threaded bolts with cover plates are made of zinc-plated steel or stainless steel.

Attaching the shock absorption mounts

• Rubber buffer with retaining washers for mounting with any bolts and nuts, in other words, for bolting through
• Rubber buffer with threaded bushings with female thread for mounting with bolts of any clamping length
• Rubber buffer with threaded bolts for easy mounting with nuts for shorter clamping lengths

The following attachment options are available for mounting the shock absorption mounts:

Types of rubber buffers

• Cylindrical
• Parabolic
• Conical
• Tapered

Winco offers the following types of rubber dampers and elastomer buffers:

Cylindrical rubber dampers are extremely versatile, durable and in widespread use

Parabolic rubber dampers are the ideal impact buffer because of their special shape. The parabolic shape of these rubber buffers generates progressive spring characteristics, enabling them to very gently absorb the shock effects.

Conical rubber buffers are also extremely versatile and durable and are often used as rubber feet for devices.

Tapered rubber-metal buffers absorb side forces better compared with cylindrical rubber buffers. The rubber also does not swell past the nominal diameter under compressive loads.

Buying rubber buffers from Winco

Winco offers a wide range of different types of buffers as a standard part. They are available with internal thread or threaded stud from M3 to M16. The most common shapes are available from stock in 3 Shore hardness levels (40, 55 and 70 Shore). In addition to the black rubber buffers, Winco also offers some rubber dampers in gray as standard or on request. Discoloration through abrasion is effectively avoided with the gray buffers.

Re: Leaking Dampers (Shock Absorbers) : Can they be repaired?

Direct Answer - Piece of cake, its a famous business in most gujri markets. You will see colorful, shiny, bright shockers hanging like kebabs... thats the place that does the re-build of shocks

What they do:
The CUT the shock (with a VISE and HACKSAW), since it comes factory sealed. They take out the old oil (assuming India is still >75% old gen hydraulic ones) - see if any tiny bushes/parts/misc needs replacement, refill with oil of your choice (YES!, question is usually "sir, what setting you want, hard, soft, medium") thick grease like oil is super hard and shock hardly compresses! Re-Seal the opened shock with a hammer and chisel and Voila - costs usually 150-300 for a bike or a jeep shock!

Would I do it:
No, have seen it being done for NUMEROUS taxi/sumo/indicas - they care a damn about ride quality, damper equality on left Vs right, so on! Sometime in I did this on my Bajaj boxers rear damper - couldnt even ride for a week, got a sore back!

As GTO said - you got a car, spend like one

BUT:
No one said stick with T@$$ - they are too expensive - find the Automobile ROAD in your city, walk around for 2 hours, find the TATA spares stockist, bargain HARD since its all 4 shocks, you will save at least 20% compared to TASS. This is only half the effort - Then find a good local roadside mech, get the shockers fit with him, will charge max Labor (T@$$ will be more!)

Best part - go to a shock rebuilder and sell your old ones for scrap, at least will fetch you a dinner for two

cheers...
