This code identifies a line of bearings that are specially manufactured to allow the bonding of a filled PTFE coated fabric (lead free, in accordance to the European Parliament “ELV” directive 2000/53/EC) on four types of backing metal layers, like carbon steel, bronze, stainless steel and Inconel 625.
The Sliding Surface is primarily composed of filled PTFE coated fabric, and other elements to guarantee the high wear resistance. The TX products find their best usage in slow-moving applications, with heavy loads, and where dry operation is required. Thanks to the thick self-lubricating layer up to 0,4 mm, this product has a high wear resistance, and can work in dirty or abrasive environment.
For this product it is not recommended the use of oil, while the use of special grease, such as silicon or lithium soap, is only possible during the assembly.
The TF type is a composite multilayer material used in the manufacture of dry self-lubricating Sliding Bearings.
The main parts composing this product are a filled modified 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 four 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 due to 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.
