SF-TEX is a high performance self-lubricating sliding material with a glass fiber reinforced carrying layer.
Kevlar Bearings are steel-reinforced, self-lubricating plain bearings with a layer of low-friction PTFE fabric. They are custom manufactured bearings across a wide range of applications requiring oscillating and rotating motions.

Kevlar, originally known as Kevlar in English, is also translated as Kevlar or Kevlar. It is the brand name of a kind of aramid fiber material product developed by the United States DuPont Company. The material was originally called "poly (p-benzoyl-p-phenylenediamine)", and the repeating unit of the chemical formula is -[-co-C6H4-CONH-C6H4-NH -]- the amide group attached to the benzene ring is the para-structure (the interposition structure is another trademark product named Nomex, commonly known as the fireproof fiber).
Self-lubricating plain bearings have such excellent characteristics as impact resistance, corrosion resistance, small vibration, low friction coefficient, wide application temperature range, large bearing capacity, long life, maintenance-free, no lubricating pollutants and so on. They are widely used in aerospace, light industry, railway machinery and other fields. As the core component of self-lubricating plain bearing, the performance of self-lubricating material determines the service performance and life of the bearing to a great extent. The excellent friction and wear properties of PTFE/KEVLAR fabric liners make them very popular self-lubricating materials for bearings. In order to make the fabric gasket play a role, it must be bonded on the friction surface of the inner and outer ring of the bearing. The stability of the bonding directly affects the performance of its own performance, and ultimately determines the performance of the self-lubricating plain bearing. However, PTFE fiber and Kevlar fiber are very difficult to bond, so it is necessary to properly treat the bonding surface and select the appropriate bonding parameters, so as to obtain a better bonding strength.
