Rubber discs and rubber sleeves, also called rubber buffers, are generally used for vibration damping and impact damping. Rubber sleeves are often used as stopper buffers in industry. Rubber discs are occasionally also used as seals.
Discs and sleeves made of natural rubber are offered in different materials and hardnesses.
While rubber discs are often used for sealing, rubber sleeves are increasingly used as rubber buffers, stopper buffers, or elastomer dampers. MISUMI already offers such a rubber sleeve as a rubber buffer with external thread or counterbore for fastening.
The rubber buffer is also available with a vulcanized metal collar, which not only allows for a firm assembly, but also sits in the anti-backlash rubber sleeve. These adhesives are also available separately. In addition to the material of the rubber buffer, the shape of the stopper buffer is also responsible for the damping characteristic. conical or rounded rubber buffers can also develop a progressive damping curve that generates increasing damping.
Depending on the application and environmental influences, MISUMI offers rubber discs and rubber sleeves in various basic materials with the appropriate resistance. An overview of the intended uses of the respective natural rubber can be found under Natural Rubber Properties as PDF .
The rubber buffers made of polyurethane rubber are also available in an antistatic version. The specific resistance of antistatic rubber discs and rubber sleeves prevents static charging. This can prevent damage to electronic components.
For high temperature applications, MISUMI offers heat-resistant polyurethane rubber, which can withstand temperatures of approx. +120°C (see Specifications for further information).
Vulkollan, on the other hand, is a very abrasion-resistant polyurethane, the abrasion resistance of which is six times higher compared to conventional polyurethane.
Ceramic polyurethane washers and sleeves contain ceramic particles. Despite a low Shore hardness, they can be machined to give them a smooth surface.
MISUMI also offers foam discs and foam sleeves. In addition to damping, these can also have sealing properties. This is achieved by the foam discs due to the closed or semi-closed pores (EPT sealer) inside the material. For semi-closed pores, the pores are sealed under load. Therefore, the type of pores must always be observed for foams in order to select the appropriate foam depending on the application. You can get help for your selection by following this link.
Further properties of natural rubbers and foams can be found in the Properties PDF.
In addition to the aforementioned basic materials, the MISUMI online shop also offers felt discs and felt sleeves. Felt has the properties of capillary action and can absorb and release liquids such as oil. In addition, felt is gentle on sensitive surfaces and is often used for polishing surfaces.
A antivibration materials can also be used for two-sided mounting to dampen vibration.
MISUMI also offers vibration damping and impact damping materials in the form of sheets.

What is Vulkollan?
Vulkollan is a highly abrasion-resistant polyurethane rubber that has high wear resistance. It is one of the high-performance rubbers that has little pressure deformation and can withstand high impact forces. In addition, Vulkollan has a high tear strength. However, over time Vulkollan may change its colour, but without losing its mechanical properties.
Which rubber is resistant?
Vulkollan is an abrasion-resistant material. It has an approx. six-fold higher abrasion resistance than conventional polyurethane materials. Vulkollan is particularly suitable for applications where high abrasion is expected.
Which rubber washer is oil-resistant?
A rubber disc made of nitrile rubber (NBR) is highly resistant to various oils. This material is often used as a seal due to its good heat resistance and abrasion resistance.
Can a rubber sleeve be glued?
A rubber sleeve or rubber disc can be stuck in or glued in. However, it must be ensured that the correct adhesive is selected in relation to the material of the elastomer. If this is not taken into account, the adhesive does not have the desired effect or even attack and degrade the elastomer. In addition, the adhesive should support the respective property of the material, e.g., antistatic or temperature resistance.
