materials uniflon® type e uniflon® is the registered trademark of the self-lubricating fabric fitted exclusively to unibal® self-lubricating spherical bearings uniflon® e self-lubricating fabric comes from a development for aerospace applications and complies with the sae-as81820 standard uniflon® e can be used in combination with different materials such as toughened steel aluminium and titanium in various environments and extreme temperatures from ­30°c to +175°c because of its composition uniflon® e is unique in the ptfe polytetrafluoroethylene fibre friction materials range composition the perfect composite uniflon® e brings you the following benefits a fabric fibres that is highly resistant to heat abrasion breaking and compression a high proportion of ptfe fibres which have superb slip properties a matrix chemically linked by a resin with a low coefficient of friction features spherical bearings with self-lubricating linings do not have a constant coefficient of friction for all applications if the applied loading increases the coefficient of friction decreases similarly if the temperature decreases the coefficient of friction increases the following figure shows how the in the coefficient of friction reduces as the temperature rises alternatives for applications at low loadings high temperature and/or higher velocity we suggest a self-lubricating lining with more suitable characteristics uniflon® type vv on request we make other maintenance-free formulas such as plastic materials self-lubricating bronzes 16 ed jan.2006 copyright © 2006 ­ schaublin-sa ­ all rights reserved
