Tufnol Bearing Materials
Tufnol bearing materials are widely used where tough, wear resistant components are needed. They give good service under a very wide range of operating conditions, including continuous temperatures from cryogenic levels to well over 100°C and in a wide variety of situations where resistance to corrosion is needed.
Although Tufnol laminates are used dry in a great many less demanding wear applications, Tufnol bearing materials are used generally self lubricating and it is preferable to used a lubricant to develop their full bearing potential. Properly designed and lubricated, Tufnol bearings give excellent service for many years and are frequently a cost-effective choice.

Bear Brand Tufnol
A cotton fabric grade specially formulated for use as a lubricated bearing material
- Enhanced wearing properties and dimensional stability
- Excellent performance in a multitude of bearing applications, using water as a lubricant, or more conventional oils of greases
- The low water absorption properties allow reduced clearances in bearings
- Enhanced electrical insulation properties
Bear Brand is used for a wide range of wearing and bearing applications, e.g. oil or grease lubricated bearings, slideways, water lubricated marine bearings, pump sleeve bearing, seal rings, mixer bearings, slipper pads, rolling mill bearings, guide bushes and a wide variety of components which are lubricated by water based process fluids in which they operate.
Tufnol Grade CBM 2008
Composite Bearing Material Synthetic fibre fabric laminated plastic bearing material
Tufnol CBM 2008 is a high performance laminated composite bearing material specially developed to give excellent results in a wide range of bearing applications. It is made from a synthetic fibre fabric, bonded together with a specially formulated thermosetting resin. The material also contains special friction-modifying compounds, including molybdenum disulphide, to enhance performance and reduce wear in bearing applications.
- Reduced wear rate
- Low friction
- Excellent dimensional stability
- Good mechanical strength
- Resistant to a wide range of working environments
- Easily machined
Suitable for a very wide range of wearing and bearing applications with water or other lubricants, and in situations where lubrication is limited or intermittent. In addition to rolled laminated tubes for cylindrical bearings and bushes, CBM 2008 is available in sheet form, which is ideal for a wide range of flat surface bearings, such as pads, slideways and thrust washers.
Tufnol Grade 2F/3/PTFE
A medium weave cotton fabric grade with its own internal PTFE dry lubricant incorporated into the resin
Tufnol Grade 2F/3/PTFE is a unique, dry-bearing material. It is a cotton fabric reinforced laminate, internally lubricated by very fine particles of PTFE uniformly distributed throughout the material. This dispersion of the PTFE right throughout the material ensures that, whatever shape of component is machined from it, PTFE is always present at the bearing surface, modifying and improving the dry friction properties.
- Self-lubricating material
- Cost-effective operation
- Reduced wear rate
- Minimizes maintenance
- Eliminates stick-slip motion and running-in periods
- Longer working life
- Easily machined
- Good mechanical strength and dimensional stability
This high performance dry bearing material has many applications in the manufacturing industries where non-contaminating, silent running, long-life dry bearings are required.
