ML-2 Self-Lubricated Bearings
ML-2 bearings stand out for their unique composite design. They combine a woven stainless steel mesh embedded in PTFE (polytetrafluoroethylene) to deliver a range of benefits:
- Eco-friendly and Lead-Free: Solid lubricants within the PTFE comply with the European Parliament's "ELV" directive (2000/53/Ec), making them a sustainable choice.
- Low Friction, High Chemical Resistance: Much like pure PTFE, ML-2 bearings offer exceptionally low friction and impressive resistance to various chemicals.
- Strength and Versatility: The metallic backing layer reinforces these bearings, providing the necessary strength and formability to tackle diverse applications
- Superior Heat Dissipation: The composite structure of ML-2 bearings allows for efficient heat transfer.
To meet your specific needs, ML-2 bearings come in various forms, including: Cylindrical bearings; Flanged bearings; Washers.
These bearings are available in thicknesses ranging from 0.75 mm to 1.50 mm (0.029 to 0.059 inches).

Structure of the composite material
| Layer | Average analyses of the material | Thickness of layer |
|---|---|---|
| Sliding layer | PTFE impregnated Stainless steel AISI 316L woven mesh | 0,50 mm |
| Supporting shell | Stainless steel AISI 316L | 0,250 ÷ 1,000 mm (Depending on final thickness required) |
| Protective layer | Sn or Zn (as per customer requirement) | > 1 μm |
Characteristics
- Extra-thick sliding layer with woven/expanded metal mesh support embedded with PTFE helps in edge loading
- High calibration / sizing assembly to compensate higher tolerances of hinge hole and pin
- Electrically conductive to enable EDP (Electro-Phoretic Deposition), also available with notches
- Right fit according to requirement to achieve desired torque value
- Noise-free / smooth operation in assembly
