TX-STE 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 recently developed the special product TX-STE made of a Stellite 6b metal-layer, which is a metal alloy made of Cobalt and Chromium, having:
- excellent mechanical resistance
- excellent wear resistance even at medium and high temperatures due to its high specific hardness
