DP4 Red PTFE Bushing Part 0040-3024

DP4 Red PTFE Bushing, PTFE composite bearings,Metal-Polymer Composite Material, Copper Plating or Tin Plating

Metal-Polymer Anti-Friction Bearings

Sliding bearing
Plain bearings are bearings that work under sliding friction.
Sliding bearing works stably, reliably and noiselessly.
Under the condition of liquid lubrication, the sliding surface can be separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has certain vibration absorption ability.

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.
