DR-A Rubber Suspension Unit
Type DR-A is a rubber suspension unit designed for machinery mountings, built using a light metal profile or steel housing depending on the unit size. For sizes starting from 60, both the housing and the inner core are constructed out of steel. The components are finished with a protective yellow print. NOWARUN supplies these units to customer drawings or equipment specifications from Hangzhou, China.

Key Benefits
- Light metal profile body keeps component weight low on smaller unit sizes
- Housing and inner core made out of steel from size 60 up for demanding loads
- Yellow protection print guards the exterior surfaces against corrosion and exposure
- Manufactured directly to customer drawings rather than sold as generic catalogue components
- Produced under ISO 9001 and ISO/TS 16949 quality management systems
- Custom crating and packaging options ensure safe arrival for overseas machinery builders
Problems It Solves
- Eliminates reliance on fixed catalogue dimensions by producing suspension units directly to customer prints
- Prevents structural failure under higher mechanical loads by providing all steel construction from size 60
- Reduces machine dead weight on smaller assemblies by using a light metal profile construction
- Protects external suspension unit surfaces from corrosion using an applied yellow protection print
Who It Is For
- Procurement engineers sourcing custom rubber suspension units according to design drawings
- Machine builders needing specific profile materials ranging from light metal to structural steel
- Equipment maintenance engineers replacing worn suspension mountings on operating machinery
- Industrial OEMs looking for suspension components manufactured under ISO 9001 and ISO/TS 16949 systems
Application Scenarios
- Rubber suspension mountings in machine construction requiring flexible vibration damping
- Agricultural equipment assemblies subject to shock absorption and continuous outdoor work
- Mining and aggregate processing machinery requiring heavy duty steel suspension from size 60
- Food processing equipment frames that require stable mounting profiles
- Wood processing machinery assemblies that call for custom rubber suspension units
Technical Features
- Light metal profile construction on smaller unit sizes
- Housing and inner core manufactured out of steel starting from size 60
- Protective surface finish featuring a yellow protection print
- Built to customer drawing and technical specifications
- Produced by NOWARUN under ISO 9001 and ISO/TS 16949 certified quality management
Materials
- Light metal profile used on smaller sizes for reduced assembly weight
- Steel used for both the outer housing and the inner core from size 60 upwards
- Internal rubber core elements providing suspension and damping characteristics
- Yellow protective surface print applied for component preservation
How It Is Made
- 1
Customer drawing review to verify unit size, core configuration and material profile
- 2
Forming or machining of the light metal profile or steel housing depending on unit size
- 3
Fabrication and machining of the inner core component out of steel for sizes 60 and above
- 4
Assembly of the internal rubber elements into the housing profile
- 5
Application of the external yellow protection print
- 6
Final inspection, tagging, and export packing according to customer specifications
Quality Control
- Material verification to ensure steel housing and core are used from size 60 onwards
- Dimensional check against the customer supplied assembly drawing
- Inspection of the yellow protection print for full surface coverage and adhesion
- Packaging inspection to ensure protection during international freight transport
Customization Options
- Custom dimensional geometry produced according to client equipment prints
- Housing material selection across light metal profile or steel based on size requirements
- Custom packaging including crates, boxes, cartons, or poly bags per order specifications
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Standard all-metal rigid machinery mountings | The DR-A rubber suspension unit provides flexibility and shock absorption, whereas rigid metal mounts transmit raw mechanical vibration into the machine frame. |
| Off-the-shelf catalogue suspension units | Custom manufacturing matches your existing assembly prints exactly, though it requires drawing sign-off rather than providing immediate off-the-shelf dispatch. |
Use Guide
- Review your machinery drawing to verify the required mounting size and profile cross-section
- Select light metal construction for lower mass requirements or specify steel construction for size 60 and above
- Provide specific interface dimensions for the inner core and housing when requesting quotation
- Inspect the protective yellow print before installing the unit into the machine housing
- Ensure mounting loads remain aligned with the internal rubber suspension axis during installation
