Super slippery engineering polyamide radically reduces friction

Supplier: Cut to Size Plastics

A special friction-bearing internally lubricated polyamide from Cut To Size Plastics is specifically engineered to radically reduce friction, wear and downtime.

It involves highly loaded slide and wear parts in machines, conveyor and transport equipment and filling, labelling and packaging technology.

LiNNOTAMGLIDE, from Cut To Size's Wearlon range, is formulated with integrated lubrication and additives to achieve a sustainable lubricating effect for the engineering plastic's entire life cycle in applications such as bearings, guide and slide rails, actuators, feeder wheels, sprockets and chain guides.

Compared with standard polyamides, a 50 per cent reduction in friction is achieved, thus radically reducing frictional heat and offering considerably higher peak load capacity. Also, undesirable stick-slip tendency is reduced to an absolute minimum, says Cut To Size NSW Manager Pat Flood.  Cut To Size manufactures machinery components for applications across Australasia from its Head office in Sydney where facilities include CNC machining facilities coupled with GibbsCAM™ and Solidworks™ software.

"Standard polyamides already offer outstanding performance as metal component substitutes, but LiNNOTAMGLIDE is in another class again. Manufactured by the leading European producer and fabricator of engineering plastics, Licharz, the fine crystal microstructure of LiNNOTAMGLIDE offers extraordinary wear resistance," says Flood.

Compared with standard quality polyamides, the product's reduced frictional heat as well as the reduced friction coefficient makes application possible at higher speeds and surface pressures. This applies not only for dry running but also for running under emergency conditions, says Flood.

Wearlon's LiNNOTAMGLIDE meets the requirements of globally recognised food safety/chemical safety EU Regulation Nr. 10/2011, as well as the FDA requirement 21 CFR 177.1500 and can be used in the production of components which come into direct contact with food.


Benefits of the product's high crystalline molecular structure and special additives include lower moisture absorption and dimensional stability. The low moisture absorption leads better dimensional stability and less of a reduction in mechanical values due to moisture

The balanced composition of the material's formula results in a friction coefficient of just 0.15, which is exceptionally low. Additionally, the tendency towards stick-slip effect is reliably reduced to an absolute minimum, says Flood.

LiNNOTAMGLiDE Pro T – an extension of the range – is especially formulated for sliding and wear prone parts, particularly where lubrication of the component is difficult or not desired.

Wearlon LiNNOTAM cast polyamides can be produced as semi-finished products or near net shape components and are virtually free of internal stress. Cut To Size offers a large selection of shapes, weights and dimensions of the broader cast polyamide range, which offers.

  • High mechanical strength, hardness, stiffness and toughness
  • High mechanical damping characteristics
  • Good fatigue resistance
  • Very high wear resistance
  • Good slide and emergency running properties
  • Good machining properties
