Belzona 1131 (Bearing Metal)

A 2-part epoxy metal repair composite with self-lubricating properties for creation of low friction surfaces and protection of lubrication systems from wear and seizure in the event of lubrication loss. This solvent-free repair composite has a unique microporous structure which allows it to trap and hold lubricating oil, minimising friction at start-up and improving the efficiency of mechanical equipment such as pumps. It has outstanding chemical resistance and will bond to almost any rigid surface without the need for hot work.

Key benefits:

Protection of equipment from wear and seizure

Reduction of friction at start up

Reduced health and safety risks as it is solvent-free

Simple mixing ratio

Application and cure at room temperature - no hot work involved

No shrinkage, expansion or distortion

Can be easily applied in thick or thin sections in one operation allowing rapid return to service

High mechanical strength and heat resistance

Excellent bonding to almost any rigid surface including steel, aluminium, copper, stainless steel, brass, cast iron and many more

Applications for Belzona 1131 (Bearing Metal) include:

Rebuilding of worn shafts at bearing locations

Repair and efficiency increase of mechanical equipment including pump rotating elements

Repair and creation of plain bearings

Creation of bushings

Sliding low friction wear layers for pipe supports
