Urethane Bumper Stops
Urethane Bumper Stops are cushioning stops made of Polyurethane. Their main function is to cushion and dampen vibrations in all kinds of equipment, machinery or transportation. At the same time, it can also be used as a positioning and limiting device to determine the exact position of the components, to prevent the components from excessive movement or shaking caused by damage or affect the normal operation of the equipment.

Advantage of Polyurethane Bump Stops
- Excellent cushioning performance
- Reduce the impact and noise
- Customizable shapes and Sizes
- Easy Installation and Maintenance
Application of Urethane Stopper
- Industrial and mechanical equipment- such as machine tools, injection molding machines, automated production lines.
- Automobile industry- like automobile chassis suspension system.
- Logistics and warehousing industry- installed in the corners of the shelves, forklift forks, the edge of the pallet and other positions, to prevent the goods from collision with the shelves, forklifts and other equipment in the process of handling, storage and damage to the goods, reduce logistics costs.
- Rail transportation industry- used in trains, subways and other vehicles, such as carriages, bogies and other parts of the platform protection facilities, highway and bridge construction, play a role in buffering shock absorption and limit.

High hardness polyurethane bump stopper is high strength and rigidity, it can withstand large impacts, and is suitable for occasions requiring strong cushioning, such as large industrial equipment, heavy vehicles, and so on.
Medium hardness polyurethane bump stop is combining a certain degree of elasticity and strength, not only can provide a better cushioning effect, but also has a certain degree of support, the scope of application is more extensive, covering a variety of industrial and civil fields.
Low-hardness polyurethane bump stop is soft texture, good elasticity, mainly used for the cushioning comfort requirements of higher, less impact scenarios, such as automotive interior parts of the cushioning, some of the precision instruments and equipment protection.
