Product Description
Product Overview

Rubber bushings, also known as silent blocks, are molded elastomer buffer components, often bonded with metal sleeves or metal inserts. Installed between two mechanical parts, they isolate vibration, absorb shock, reduce noise, and compensate for minor displacement.

We manufacture rubber bushings in NBR, EPDM, Silicone, and FKM materials. Custom sizes, hardness, and shapes are available according to drawings or samples for automotive and industrial vibration isolation applications.

Key Features & Benefits
  • Molded from premium rubber with optional materials: NBR, EPDM, Silicone, and FKM; select models feature metal insert bonding.
  • Excellent vibration isolation, shock absorption, and noise reduction performance.
  • High elasticity and flexible deformation to absorb impact and compensate for small positional deviation.
  • Good aging resistance and abrasion resistance for a long service life under proper working load.
  • Custom dimensions, hardness, and shapes supported; OEM and prototype orders accepted.
  • Reduces metal-to-metal friction and protects mechanical components from impact damage.
