TCT bushings are made from two layers:
A fibreglass epoxy resin structure which stiffens the bushing and provides rigidity
A self-lubricating sliding layer: a layer of PTFE and highly resistant synthetic fibres, impregnated with PTFE-based solid lubricant
Variant TC-FC
TC-FC bushings are wrapped with fibres and are impregnated with thermosetting resins. This light bushing has a PTFE layer which provides the bushing self-lubricating properties.
The bushing is characterised by its high load capacity and is particularly suitable for frequent starts and stops.
The TC-FC bushings have a dimensional range of 2.5 mm thickness. They can therefore be mounted instead of a wrapped bushing.
Advantages of TCT bushings
TCT bushings are self-lubricating, no need for oil grooves.
They are often used to replace bronze bushings for which maintenance and relubrication is required.
TCT bushings have an excellent load resistance such as metal bushings with the same lifetime.
Moreover, they can be set up in corrosive environment without damage thanks to their superior chemical resistance compared to other bushings.
Limitations of TCT bushings
TCT bushings have a specific dimensional range, especially in terms of thickness.
TCT bushings have a low resistance to steam
Applications
TCT bushings often replace bronze bushings in lifting equipment, construction machinery, transport and agricultural equipment. They are also preferred in marine equipment.
