DR-C Rubber Suspension Unit
The DR-C rubber suspension unit uses a steel outer housing and an inner steel core separated by standard rubber inserts, designed with a steel tube configuration for plug-in connection. Finished in yellow protection paint, this torsional rubber spring assembly isolates vibration and absorbs mechanical shock through the elastic deformation of the internal rubber cords. NOWARUN supplies these units manufactured to customer prints and specifications for direct integration into industrial equipment.

Key Benefits
- Plug-in steel tube connection allows direct insertion and rapid mounting onto mating structural shafts
- Steel housing and steel inner core construction provides rigidity under continuous mechanical load
- Internal rubber elements absorb vibration and torsional deflection without requiring internal metal springs
- Coated in protective yellow paint to resist surface corrosion in exposed operating conditions
- Manufactured to customer specifications rather than restricted to fixed catalogue selections
- No internal metal-on-metal sliding contacts, eliminating routine lubrication requirements in service
Problems It Solves
- Complex mechanical mounting brackets eliminated by using a direct plug-in steel tube interface
- Premature suspension failure caused by unpainted metal housings corroding in harsh industrial plants
- Vibration transmission through rigid mounts damaging adjacent bearings and structural frames
- Difficulty sourcing replacement torsional rubber units when original suppliers discontinue drawings
Who It Is For
- Mechanical design engineers developing machinery with plug-in elastomeric suspension mounts
- Equipment manufacturers sourcing custom-made steel torsional rubber springs to drawing
- Procurement managers needing contract manufacturing for welded steel rubber suspension units
- Plant maintenance engineers replacing worn plug-in rubber suspension units on operating machinery
Application Scenarios
- Industrial machinery construction requiring plug-in torsional rubber suspension connections
- Agricultural equipment assemblies subject to constant oscillatory vibration and chassis shock
- Screening and conveying equipment in mining and aggregate handling installations
- Material handling transfers requiring elastomeric dampening through plug-in modular mounting
- Wood processing machinery where torsional rubber units absorb intermittent mechanical impact
Technical Features
- Steel tube geometry arranged for direct plug-in connection
- Inner core and outer housing both fabricated from steel
- Elastomeric dampening provided by high standard rubber inserts
- External surfaces coated with yellow protective paint
- Elastomeric torsional deflection without internal lubrication needs
Materials
- Steel housing providing structural rigidity under continuous mechanical vibration
- Steel inner core designed to transfer torque into internal rubber elements
- Standard rubber inserts engineered for elastic deflection and shock absorption
- Protective yellow paint applied across exposed external steel surfaces
How It Is Made
- 1
Review of customer engineering drawings and plug-in tube dimensional specifications
- 2
Forming and machining of the steel outer housing and internal steel core
- 3
Insertion and pre-stressing of the rubber dampening elements between core and housing
- 4
Assembly verification of the plug-in connection tube dimensions
- 5
Surface preparation and application of protective yellow paint
- 6
Final inspection, cleaning, and export packaging according to specification
Quality Control
- Dimensional verification of the steel plug-in tube to ensure proper mating fit
- Visual inspection of the rubber insert seating within the housing and core
- Paint coverage and adhesion checks on the yellow protective coating
- Packaging inspection to prevent transit damage prior to overseas shipment
Customization Options
- Plug-in tube diameter, wall thickness, and length manufactured to drawing
- Outer housing and inner core steel dimensions adjusted to load requirements
- Specific packaging configurations arranged in cartons, crates, or boxes
- Surface protection options provided to match specific environmental requirements
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Flanged rubber suspension units | Plug-in tube connections save lateral mounting space and install faster, but rely entirely on shaft engagement for axial retention |
| Helical steel coil springs | Rubber suspension units provide built-in dampening and resist lateral loads without guides, but offer less overall travel |
| Uncoated bare steel rubber mounts | Yellow protective paint prevents early atmospheric rust in exposed machinery, but can chip if struck by loose debris |
Use Guide
- Provide engineering drawings indicating exact plug-in steel tube dimensions and tolerances
- Ensure the mating plug-in shaft matches the inner profile without forcing misalignment
- Avoid exposing internal rubber elements to aggressive industrial solvents or direct flames
- Verify the yellow protective coating remains intact during mechanical assembly
- Fasten all connecting hardware securely to prevent unwanted axial shaft slip
