TX-T1 Type
The TX code identifies a family of self-lubricating bearings and washers that are specially manufactured with a bonding of a filled PTFE coated fabric (lead free, in accordance to the European Parliament “ELV” directive 2000/53/EC) to various baking metal layers like: carbon steel, bronze, stainless steel and Inconel 625.
In addition to the standard metal-layers, Slib Italy has developed the special product TX-TI1 made of a Titanium metal-layer, and suggested for applications requiring:
- high resistance to corrosion
- excellent mechanical resistance
- low specific gravity
This product is suitable also for medical applications.

Also the TX-TI1 types can be produced as PLUS model, which is an enhanced type of lubrication treatment to reduce even more the coefficient of friction.
