CRC Distribution offers Orkot® greaseless marine bearings, made from a proprietary composite solution. Engineers use these marine bearing solutions in hydroelectric projects, shipbuilding, offshore oil and gas, and other industrial applications.



Tubes, Sheets, Custom Shapes

Orkot® is offered in tube, sheet, or custom shapes. Standard tubes are 24 inches long and available in a variety of wall thicknesses. Standard sheets are 24 inches x 48 inches, with larger sizes available. Sheets can be produced up to 6 inches thick or bonded for custom designs. CRC can provide finished parts, raw tubes, or raw sheets.



Benefits include:

Dimensionally Stable
Orkot materials have an almost 0% swell in extended underwater use.

public

Environmentally Friendly
Orkot is ideal for water-lubricated applications, or it can run dry without needing external lubricants.


build

Easy Installation
Orkot can be press-fit, bonded, or mechanically fastened. The material can be freeze-fitted without danger of shattering.

restore

Exceptional Wear Resistance
Orkot bearings withstand edge loading and misalignment.



Easily Machined
As a general guide, methods used for brass, aluminum, or lignum vitae will apply to Orkot® materials.

Low Friction
Orkot’s low-friction bearing surface extends dry running capabilities and reduces friction and wear rates.

Tested and Certified
Orkot’s low-friction bearing surface extends dry running capabilities and reduces friction and wear rates.



How Orkot® Marine Bearings Work

Orkot® incorporates unique synthetic composites that work at the molecular level, incorporating long chains of chemically cross-linked polymer molecules in a dense three-dimensional network. This construction ensures the integrity of the solid material. Once the polymer has cured and solidifies, the material is processed into either tubes or flat sheets.

Orkot does not melt at high temperatures, and extensive testing shows no brittleness or chatter in extreme cold or even cryogenic conditions. The laminated structure withstands extremely high pressures perpendicular to the laminate. In all forms, Orkot has dimensional stability in either arctic or tropical seas.

Solid Lubricants

Orkot uses solid lubricants for dry running to ensure outstanding wear life. Components in seawater show negligible swell. In any form, the material used for Orkot machine bearings maintains a high degree of mechanical and chemical stability and has excellent water-lubricating qualities.

How is Orkot® Manufactured?

The drawing below illustrates how Orkot® thermoset composite materials are made. The manufacturing process incorporates a woven fabric and solid lubricants within a thermosetting resin matrix.





Orkot® TXMM is a type-approved product by the American Bureau of Shipping for use in marine bearing applications.
