Tubes, Sheets, Custom Shapes

Orkot® marine bearing material 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 of Orkot®:


format_color_reset

Dimensionally Stable

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

public

Environmentally Friendly

Orkot® is ideal for water-lubricated bearing applications, or it can run dry without 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® TXMM is a type-approved product by the American Bureau of Shipping for use in marine bearing applications.



How Orkot® Marine Bearings Work

Orkot® marine bearings incorporate 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® marine bearings maintain a high degree of mechanical and chemical stability and has excellent water-lubricating qualities.

How is Orkot® Manufactured?

The illustration below shows the manufacturing process of Orkot® thermoset composite materials. The process incorporates a woven fabric and solid lubricants within a thermosetting resin matrix.
