Cast Nylon 6 Oil - Omniamid Oil

Cast Nylon 6 with the addition of 6% of special lubricating oil which remains in solution in the material. The unique method of production results in a micro distribution of oil particles with a homogeneous dispersion. This produces a notable improvement in the self-lubrication property as well as the shock resistance. Machining is also much easier. 


FEATURES 

Self-lubricating: the friction coefficient is the lowest of all the cast nylons 
Wear resistance: better than PA6 natural  
Tensile stress and compressive strength is like Omniamid G whilst shock resistance is higher, the E-modulus is lower
Machining: excellent on machine tools
Colour: orange and black 


WEAK POINT
 
It is hygroscopic, even if to a lower extent than natural PA6 G. Because of the molecular structure, the large-sized cast pieces have better quality than those of small dimensions.


APPLICATION

Mechanical: thanks to its excellent self-lubricating property, high shock resistance and compressive strength, together with the possibility to produce large-sized parts, it is widely used to produce bearings and bushings of large diameters as well as pulleys, wheels and anti-wear guides. Because of its excellent abrasion resistance it is used for gear wheels, guide bearings, bearings, sliding bearings, etc. in the building of parts for construction machines, excavators and earthmovers. In the shipbuilding industry its better weather resistance makes it suitable for rollers, haulage, sliding guides, bearings. In cable-car systems its usage includes pulleys, wheels and sliding blocks. 

Food contact: it cannot be used in contact with food.
 
Electrical: usage in the electrical field is to be avoided as the electrical properties change with the change in moisture content. 

Chemical: it is resistant to alkali, inorganic compounds and solvents. 

Friction coefficient: steel with bearing made of Omniamid G - HR - OIL
The graph shows the friction coefficients of cast polyamides in function with the contact pressure.
On the ordinate: contact pressure.
On the abscissa: friction coefficient.
Note that Omniamid OIL has the lowest friction coefficient.
