TF - F51 TYPE
The TF code identifies a family of self-lubricating bearings and washers made by a composite multilayer material. The main parts composing this product are a modified filled PTFE layer (lead free, in accordance to the European Parliament “ELV” directive 2000/53/EC) for the sliding self-lubricating surface, and a special primer used to allow the sintering of the PTFE layer to various types of baking metal layers like: carbon steel, bronze, stainless steel and Inconel 625. Thanks to its structure, the TF type provides an excellent match between the mechanical strength of the steel and the low coefficient of friction of the modified PTFE sliding layer.
This is a product that can be used in applications with medium loads and in a clean environment with low levels of abrasive elements such as metal powders. It can also be used with special mineral oils and specific greases such as silicone compounds or lithium soap.
