Product Overview
Rubber-metal bushings are composite components made by vulcanization bonding of elastomer rubber and metal inner/outer sleeves. The integrated vulcanized structure eliminates slipping between rubber and metal under dynamic load. This universal series adopts a shared base framework; only the rubber formula, bore size, flange layout, mounting holes, and limit grooves need adjustment to switch application scenarios, cutting new mold costs and shortening development cycles. It balances flexible damping and rigid load-bearing capacity for static and cyclic dynamic working conditions.
Core Features
- Firm vulcanization bonding between rubber and metal, resistant to delamination under repeated vibration
- Adjustable rubber hardness (Shore A range configurable) to tune stiffness, damping, and isolation effect
- Metal substrate provides stable positioning and high load capacity, anti-torque deformation
- Rubber compound options for oil resistance, ozone resistance, low temperature resistance, or aging resistance
- Modular design: modify inner sleeve, outer shell, flange, stop grooves and mounting holes for different assemblies
- Stable performance under continuous cyclic load, low noise transmission
- Batch vulcanization production with consistent bonding quality
Application
This universal rubber-metal bushing family covers multiple industries:
✅ New energy vehicle chassis & suspension assembly
✅ Energy storage equipment vibration isolation
✅ Transformer and power equipment shock cushioning
✅ Charging station equipment mounting damping
✅ Construction machinery & hydraulic system
✅ Industrial pump, motor, and reducer vibration isolation
✅ Rail transit auxiliary support
Manufacturing Process
Metal insert pretreatment (degreasing, sandblasting, adhesive coating) → rubber compound preforming → vulcanization molding under temperature & pressure → post-curing → deburring → bonding & dimension inspection → fatigue performance sampling test.
Customization
Inner metal sleeve OD/ID, outer metal shell shape, rubber thickness, Shore hardness, flange, limit groove, mounting counterbore, thread interface, and special anti-media rubber formulations are available on request. Special surface treatment for metal parts (zinc plating, passivation, powder coating) can be provided.
