DMB Buffer, Ø125mm H100mm M16x36mm, NR 60 ShA Standard Steel
Polymax DMB High Deflection Buffers/Bump Stops or Feet - Round Plate Single Fixing Bolt.
They are extensively used as rubber bump stops on slow moving machinery and designed to give high deflection to reduce impact force at rest.
Applications
- Cranes
- Trains
- Heavy Goods Vehicles
- Boats
Can be made in alternative rubber compounds and stainless steel.
Natural rubber (NR) is a versatile and adaptable material characterised by its ability to accept and recover from large deformations. Unlike steel or other metals, it possesses some inherent damping characteristics and can store a larger amount of elastic strain energy per unit volume, making it ideal for use in dampers or as a rubber spring. Natural rubber compounds have a high tensile strength, long fatigue life, and excellent tear resistance.
Natural rubber compounds also exhibit low hysteresis compared with other rubbers. This results in lower heat buildup during repeated deformations, making it an ideal polymer for vibration isolation. Other mechanical properties such as resistance to fatigue, abrasion, tear, and flex are also generally superior in these compounds compared to synthetic elastomers.
NR compounds are not suitable for applications requiring contact with oil, kerosene, diesel, petrol, or solvents like benzene and toluene. These compounds also exhibit poor oxygen and ozone resistance, although this can be somewhat improved by adding antioxidants.
