Plastic sliding bearings
OMC
OMC is an oil-impregnated nylon material. It is a high-strength and self-lubricating plastic made from a nylon monomer and which stores lubricant as a result of a catalysing polymerization reaction.
OMC is popular in hydroelectricity technology, metallurgical machinery, rubber roller machinery and vulcanisation machinery.

|---|---|---|---|---|---|---|---|
| 14 MPa | 20 MPa | -40°C | +80° | 0.12 | 0.16 | HRC R118 | 1 × 10 / °C |
GMC
GMC is a reinforced nylon material. It is filled with fibreglass, which gives it impressively high levels of stability and rigidity along with low stick-slip.
This material is commonly used in the mining industry, in shipyards and in the paper manufacturing industry.
