Moulded PTFE Bushes

Moulded PTFE bushes are hollow fluoropolymer sleeves formed as near-net stock or finished bearings for rotary and linear support. Their low-friction, chemically resistant surfaces suit equipment where external lubrication is undesirable, while fillers can improve wear, load support and dimensional stability.

Questions about moulded ptfe bushes

What should I send to identify moulded ptfe bushes?

Send inside and outside diameters, length, flange or groove details, PTFE grade, load and motion. Provide finished running clearance and housing fit separately from the free bush dimensions. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select moulded ptfe bushes?

Choose grade and wall section from shaft material, load, speed, temperature, chemicals, clearance and lubrication restrictions. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
