FDA PTFE Bush Manufacturer

Applications

Where FDA PTFE Bush is used

Plain bearing carrying radial load without grease, relying on the polymer’s low friction where oil lubrication is unwanted or impossible.

Specified where FDA 21 CFR 177.1550 listed resin is required for direct food, dairy and beverage contact, with cleanability and no taste transfer.

The bush form is specified where a food or pharmaceutical machine needs a dry-running bearing; the same FDA-listed resin in sheet form would be cut for gaskets instead.

Common in dairy, brewing, edible-oil and bottling lines, and on filling equipment that is washed down between batches.

Process

Manufacturing process

HEMSUN ENGG. INDUSTRIES produces FDA PTFE Bush using matched punch-and-die compaction of PTFE fluoropolymer resins. Green preforms are sintered in digital PID-controlled ovens with multi-point thermocouple logging, followed by precision CNC lathe turning to achieve micron-level concentricity and smooth surface finishes.

Material

Material selection notes

The PTFE fluoropolymer material utilized in FDA PTFE Bush exhibits exceptional dielectric insulation (up to 80 kV/mm) and zero moisture absorption (<0.01%). It withstands thermal cycling between cryogenic temperatures and +260°C without embrittlement or dimensional degradation in demanding industrial environments.

Selection

How to specify your order

When requesting a proposal for FDA PTFE Bush, please provide 2D/3D component drawings with dimensional tolerances, material resin grade (virgin or specific filler ratio), operating pressure/temperature conditions, and required batch quantities. Our engineering team reviews manufacturability and returns quotes within 24 hours.
