DK-S Rubber Suspension Unit
The DK-S rubber suspension unit combines a light metal outer profile with an inner steel tube configured for plug-in connection, protected by a yellow finish. Manufactured by NOWARUN in Hangzhou, China, to customer drawings or samples, it delivers elastomeric suspension and damping functions across industrial machinery construction, food processing, agriculture, and material handling systems without requiring standard off-the-shelf assemblies.

Key Benefits
- Light metal profile outer body keeps overall assembly weight low while maintaining structural rigidity
- Steel tube core configured specifically for plug-in connection simplifies mechanical mounting and alignment
- Yellow protection paint provides an external barrier layer for extended service in industrial environments
- Internal rubber suspension mechanism accommodates torsional movement and dampens structural vibration effectively
- Manufactured directly to customer drawings or provided samples rather than supplied from fixed stock
- Produced under an ISO 9001 and ISO/TS 16949 certified quality management system
Problems It Solves
- Heavy all-steel suspension bodies adding excessive weight to dynamic or oscillating machinery assemblies
- Rigid mechanical joints transferring damaging structural vibration and shock directly into drive components
- Corrosion of exterior metal housings in exposed operating environments without protective paint layers
- Inability to source matching replacement suspension units when catalogue stock dimensions do not fit
Who It Is For
- Machine design engineers requiring a custom light metal rubber suspension unit with a plug-in connection
- Procurement managers sourcing contract-manufactured elastomeric damping units to tight drawing specifications
- Agricultural equipment OEMs seeking resilient mounting elements with painted protective finishes
- Industrial machinery rebuilders replacing worn rubber suspension assemblies that lack original supplier support
Application Scenarios
- Torsional oscillation and suspension mountings in machine construction requiring plug-in steel tube shafts
- Agricultural equipment linkages subject to repeated vibration, deflection, and shock loads
- Vibratory screens and feeder systems in mining and aggregate processing facilities
- Food processing conveyor supports needing low-maintenance elastomeric damping elements
- Wood processing machinery frameworks requiring continuous vibration isolation under light metal housings
Technical Features
- Light metal profile exterior housing for reduced tare weight
- Inner steel tube engineered specifically for plug-in mechanical connection
- Protective yellow paint applied to the exterior surface
- Internal elastomeric rubber cords providing torsion, damping, and self-centering
- Manufactured to client technical drawings or physical samples
Materials
- Light metal profile for the outer suspension housing
- Steel tube for the inner plug-in connection member
- Internal elastomeric rubber inserts for suspension and vibration damping
- Yellow protective paint coating on metal surfaces
How It Is Made
- 1
Drawing or physical sample analysis to verify profile geometry and plug-in fit
- 2
Extrusion or machining of the light metal outer profile
- 3
Preparation and sizing of the inner steel connection tube
- 4
Insertion and assembly of the internal rubber elements under controlled pretension
- 5
Application and curing of the yellow protective paint
- 6
Final dimensional inspection, packaging, and export preparation
Quality Control
- Dimensional verification of outer light metal profile against customer drawings
- Bore and fit inspection of the inner steel tube for plug-in connection tolerances
- Visual assessment of yellow protection paint coverage and adhesion
- Factory operating under audited ISO 9001 and ISO/TS 16949 quality standards
Customization Options
- Overall profile length and mounting features machined to drawing requirements
- Inner steel tube inner and outer diameters adapted to mating plug-in shaft dimensions
- Alternative packaging configurations arranged to customer specifications
- Manufactured from technical prints or reverse-engineered from customer-supplied samples
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Cast iron suspension unit | The light metal profile significantly reduces overall weight but offers lower maximum static tensile strength |
| Flanged bolt-on suspension unit | The plug-in steel tube allows faster modular insertion but requires an accurately sized mating shaft |
| Standard catalogue rubber unit | Custom manufacturing matches non-standard machine layouts but requires production lead time rather than off-the-shelf delivery |
Use Guide
- Provide a detailed 2D or 3D technical drawing indicating critical mounting and tube dimensions
- Ensure mating plug-in shaft fits the internal steel tube tolerances without excessive play
- Inspect the yellow protective paint before installation to confirm the coating remains undamaged
- Verify that operational torsional deflection remains within intended elastomeric limits
- Follow standard assembly procedures to prevent damaging the light metal housing during installation
