Product Description
DP4 Flange Bushings RED PTFE BUSHING, Sliding Bushings, Metal-Polymer Composite Material, Copper Plating or Tin Plating
Metal-Polymer Anti-Friction Bearings
Quality Plain Bearings and Sleeve Bearings and Material Handling Solutions, Lead-free material compliant to RoHS specifications
Bushing Type
Sleeve; Flanged
Type (PTFE coated sliding bushing) Steel + porous bronze sinter + PTFE
Lead-free flange bushings have PTFE sliding surfaces and tin-plated steel bodies, making them an effective substitute for places that cannot or must not be lubricated. Select this type for low speed, high load applications, or low speed and high load applications. This sleeve is suitable for applications where friction and heat should be avoided. The sleeve can also be used, for example, in oil or water, and has good corrosion resistance. In addition, the model can withstand very high and very low temperatures and has a low coefficient of friction. For example, in fitness equipment.

PTFE CDIN 1494 Flange sleeve bushing, Flange Size Bushing, ROHS Approved
Sliding surface made of PTFE in tinned steel frame
Especially suitable for places where lubrication is not possible or desirable.
DP4 flanged bearing Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication.

Structures
1. PTFE/Fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-Fibre mixture.
3. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
Characteristics
- DP4 flange bushing has low friction bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
- Very good performance in lubricated applications
- Good performance in greased applications
- Suitable for linear, oscillating and rotating movements
- Lead-free material compliant to ELV, WEEE, and RoHS specifications
- Approved to standard DIN EN 1797: 2002-02 and ISO 21010: 2004-04 (Cryogenic Vessels – Gas/Material Compatibility) for piping, valves, fittings and other components in both gaseous and liquid oxygen for up to maximum temperature of 60°C and oxygen pressure of 25 bars.
- Approved to standard FAR 25.853 and FAR 25.855 - Federal Aviation Regulations – making it suitable for interior aircraft applications
