Product Description

 

Maintenance-free, self lubricating bearing polyacetal Coted Strips

 

The structure of this prelubricated yellow bushing strip material consists of spherical powdered bronze sintered onto a steel backing and polyacetal resin impregnated into the surface.

Metal-polymer-composite material Polyacetal-Copolymer bearing material (POM)

 

Cylindrical bushes Flanged bushes Thrust washers Flanged washers Strips

 

VIIPLUS POM Coted bushing based sliding bearing also similar Dx bushing, boundary lubrication bearing,SF-2 oilless bearing,dry bearing, POM lined plain dry bush. It has similar material structure with DU bushing. The difference is the layer with POM coated. We are leading exporter of POM Coated Bushing,sliding bearing,boundary lubrication bearing,Dry Bearing in china.

Wrapped POM Lined Bearings   Steel + Bronze Powder + POM(DX) Strips

 

Our POM range of wrapped acetal lined bearings are suitable for rotary and oscillating movement applications.

The VIIPLUS plain bearings are available in metric and imeprial sizes as standard.

Our in-house machining service is able to offer non-standard sizes to suit customer specific requirements.

Characteristics

 

VIIPLUS range of wrapped POM lined bearings are suitable for rotary and oscillating movement applications. They benefit from long re-lubrication intervals, no absorption of water, outstanding damping behaviors and have a low suceptibility to edge loading.

 

Strips PAS are available as an even material section. This material section can be used to make sliding elements in a variety
of shapes.

 

Metal - Polymer Composite Bearing With POM Material 

 

The VIIPLUS range are ideal for the automotive, machine building and agricultural industries and indeed any application where lubricant cannot be supplied continuously.

Material Information

  • Low-maintenance standard solutions

  •  

Plain Bearing Production

 
Sliding elements in a great variety of designs are produced from the composite material in cutting, stamping and shaping processes.
 
 

Standard designs are:

  • Cylindrical bushes

  • Thrust washers

  • Strips

 

If these material sections are used to create slide paths, they have the following main functions:

 

  • Absorbing and transferring forces acting vertically to the running surface

  • Fixing moving components to each other

  • Ensuring guidance accuracy for axial movements over the entire service life


 

Strips are available in two material groups:

  • Material group P1 for maintenance-free, dry-running applications

  • Material group P2 for low-maintenance, lubricated applications


For the advantages of each group and help deciding which material group is best for the relevant use, please refer to the information provided in the section cylindrical bushes, flange liners and thrust washers.


VSB-20 Flange liners PAF

  • Marginally lubricated bushings for grease or oil lubricated applications

  • Standard parts contain grease indents in the sliding layer; plain sliding layer available by request

  • Optimum performance under relatively high loads and low speeds

  • Suitable for linear, oscillating and rotating movements

  • Wide range of parts available from stock

 
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.


Strusture

 

Our wrapped POM lined bearings have a high wear resistance and low friction even with very small quantities of lubricant
The surface carries a pattern of circular indents which should be filled with grease on assembly
Low carbon steel gives exceptionally high load carrying capacity and excellent heat disspation

 

1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
