ONE of the versatile families of thermoplastics from Dotmar EPP is the Nylatron range, the self-lubricating properties of which makes it suitable for applications where there are large open gears in operation, especially cast iron or steel gears that are open to the atmosphere.

Because Nylatron gears don't have exposed lubricant - lubricant is built into the material from which the gears are made - they don't attract dust, dirt and grime onto any of the moving parts.

This unwelcome grime can act as a grinding paste, damaging gears and decreasing their longevity.

Gears engineered from Nylatron MC901 also contain a built-in heat stabiliser. This permits longer usage in temperatures of up 120°C, as well as low noise output, fatigue resistance and dimensional stability.

Dotmar EPP engineering director Bruce Armstrong says the use of Nylatron MC901 in this type of application means the lifespan of gears may be up to five times longer than the metal compound it has replaced.

"Added to this, the better shock resistance of Nylatron MC901 compared with metallic gears translates into a vastly improved tolerance to misalignment, as well as higher resilience. Benefits include much lower levels of vibration transmitted to the bearings,” he added.
