Glacier Style Bushes – DU Type

Innovative and quality bearing custom design

Teflon Sleeve Bushing- PTFE Bearing Supplier

Du Bearing DefinitionSelf Lubricating PTFE Material

Tailored Solution

Du bearing definition: The structure of the bushing bearings consists of a rigid steel DU bushing or corrosion-resistant bronze backing (DU-B), which provides mechanical strength, while a porous sintered bronze interlayer impregnated with a homogeneous mixture of PTFE and lead provides low friction and high wear resistance.

DU self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions.

DU – Self lubricated plain bearing. Carbon steel shell with sintered bronze layer filled with PTFE. Sometimes referred to as a ‘Wrapped Bush’ or ‘Glacier Bush’

The high performance self-lubricating bearing material

DU Type bushes consists of three bonded layers: A steel backing strip and a porous bronze matrix, impregnated and overlaid with the PTFE/ lead bearing material.

1. PTFE           0.01~0.03mm

2. Porous bronze 0.2~0.3 mm

3. Steel / Bronze backing 0.7~2.3 mm

4.Tin-plating 0.005mm or copper plating 0.008mm

DU sliding dry bearing gives you the widest application range of any self-lubricating bearing.

A unique, composite bearing material

Characteristics and application of modified polytetrafluoroethylene

PTFE is one of the best corrosion resistant materials in the world, so it is known as “the king of plastics”.Because of its high and low temperature resistance, resistance to chemical corrosion and weathering resistance, low friction coefficient, excellent electrical insulation, self-lubrication and non adhesive and so on the excellent properties of other materials can not replace in compressor oil chemical industry, aerospace, automobile, electron, semiconductor, medical, architecture, textile industry, food industry and other industry plays an important role.

But pure PTFE itself also has some limitations, can not fully cover a variety of application conditions, so the modification (filling) treatment of PTFE to improve its performance, to meet a wider range of industrial needs.

The filling medium usually includes: glass fiber, barium sulfate, carbon fiber, copper powder and lubricant (graphite, molybdenum disulfide), etc., generally filling modified with high compressive strength, wear resistance, good thermal conductivity and low thermal expansion, lower friction coefficient, cold flow resistance and creep resistance and other properties.But because the filling medium is different, the number is different, its characteristics will also change to some extent, can be customized according to the actual needs.

Widely used in the production of gaskets, valve seats, bearings, sliders, piston rings, insulation sleeve, oil-free lubrication seals, etc.

Viiplus as self-lubricating bearing industry brand, has always been committed to become the world famous self-lubricating bearing solution and its suppliers, rely on independent research and development advantages, key development, expansion of the application of new material and new focus to the study of fluorine plastic material production, better expanded the product line, providing customers with solutions of various kinds of industrial demand.

To provide customers with bearing solutions to various industrial needs.

The modified PTFE products developed and produced by VIIPLUS have the characteristics of good creep resistance, chemical corrosion resistance, cold flow resistance and chemical corrosion resistance.

PTFE thrust washer, sleeve bearing bushings

  • By adding different medium fillers to improve the bearing performance of some aspects of the thrust washer, so that it can be applied to a wider range of fields.
  • By adding different medium fillers to improve the performance of bushings & bearings material, it can be reprocessed into a variety of products to meet the actual needs.
  • The polytetrafluoroethylene resin and a variety of fillers (carbon fiber, copper powder, molybdenum dioxide and other lubricating materials) after mixing by molding, sintering, turning, and then through the single side of the nano treatment.It has the advantages of high strength, wear resistance, good thermal conductivity, reduced thermal expansion, good sliding action and so on.

We have always been customer-oriented, and always adhere to the mission of becoming a high-quality self-lubricating bearing and its solutions supplier and strive for it.We can further customize bearing solutions according to the specific needs of customers to meet a wider range of industrial needs.

PTFE lined wrapped bearings are suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the mating metal surface.

  • DU requires no lubrication
  • Provides maintenance free operation
