Advantages over traditional bearing materials
- Load capability comparable to metal bearings
- Extend intervals between greasing
- TXM Marine offers the option for maintenance free, dry running operation
- Tolerant to misalignment and shaft/structure deflections
- Low friction upon movement after long stationary periods
- Withstands permanent loading
- Particularly effective where grease lubricants tend to be squeezed away
Fitting method
Freeze fitting using liquid nitrogen is a fast and efficient assembly method for an Orkot® Marine bearing. The thermal properties of the material allow a good clearance between the bearing and housing when frozen and the material does not become brittle at cryogenic temperatures. Freeze fitting using dry ice and alcohol will only provide the required clearance when using very light interferences. As such it is rarely a viable method in its own right and will often require press fitting as well.
