What is Supamide

Supamide is a specially formulated self-lubricating, super tough engineering plastic, developed to overcome specific challenges encountered with current engineering plastics available within the market.

Supamide offers improved properties over materials such as Phosphor Bronze and has a higher continuous operating temperature than alternative engineering plastics, within humid and wet conditions.

Industry engineers have found that our low shaft wear and high impact strength make us most suitable for demanding applications and is therefore widely accepted throughout multiple industries as a high quality and cost-effective solution to surface wear.

Why Supamide

Proven Performance

Supamide has two decades of proven performance throughout the industry.

Self-lubricating

Supamide is a true self-lubricating material. Whilst lubrication does lower friction, in many instances it is not necessary.

Super Tough

Supamide has a very high impact strength, preventing costly problems like cracking and flange breakage.

Low Shaft Wear

Controlled tests and filed applications have shown that Supamide bushes produce very little shaft wear, even without lubrication.

High Operating Temperatures

Supamide has a maximum operating temperature of up to 130°C. Supamide does not become hard, abrasive and brittle when run at 100°C in wet and humid conditions.

Popular Supamide Applications

Underground hopper door and trunnion bushes.

LHD diff trunnion bushes.

B6460 winch bearing inserts.

65 ton low bed walking beam bushes.

Underground loco motor axle bushes.

Crane slipper pads and sheaves.
