Suspension & Industrial Rubber Bushes
Precision-moulded rubber bushes, silent blocks, and bonded sleeves designed to absorb shock loads, allow multi-directional joint oscillation, and prevent metal-on-metal mechanical wear. At Sarthak Industries, we engineer bushes with outstanding load bearing capacity.

Material Selection Guide
Choosing the right rubber polymer compound is essential to ensure longevity and prevent seals from failing under pressure.
Polyurethane (PU)
Extremely high load bearing, superior tear strength, and abrasion resistance. Perfect for performance off-road vehicle suspension arm pivots.
Natural Rubber (NR)
Outstanding dynamic fatigue life and shock-absorbing flexibility. Highly resilient compound offering smooth, quiet machinery operations.
EPDM
Outstanding resistance to environmental weathering, UV rays, ozone, steam, and glycol-based coolants. Ideal for outdoor hinges.
Nitrile (NBR)
Excellent resistance to petroleum, lubricants, hydraulic oils, and grease. Recommended for bushes in heavy industrial machinery joints.
Applications & Custom Capabilities
- Suspension Pivots: Effectively absorbs torsional, axial, and radial forces in steering and control arm linkages.
- Precision Lathe Turning: In-house machining of inner and outer metal sleeves to achieve precise interference fits.
- Hydraulic Assembly: Pressing and assembling services to supply drop-in metal-rubber suspension bushes.
- Custom Compounds: Stiffness tuning (50 Shore A to 90 Shore A) to control deflection rates and vibration absorption.
