Self-Lubricating Bronze Bushing grease-lubricated composite bearing

VIIPLUS BUSHING MADE IN CHINA is similar to foreign made DS bush,and may be operated without lubricant or under an trace of oil.It is of low friction,anticorrosion and is of long life.This is now applied in machines under oscillating motion and in open field or in corrosive environment such as hoisters,bulldogger,tower cranes,andprinting or dyeing machines for textiles.

If your business is in sliding bearings PTFE composite bushings, please inform us of your project situation and strips sizes requirements in the inquiry. We will efficiently provide you with product selection solutions and quotations.

Rolling bearing is a kind of rolling bearing, which is made of high quality cold rolled steel plate, sintered porous spherical bronze powder in the middle, and then rolled on the surface of porous spherical bronze powder with modified polyformaldehyde and rolled.
This type of bearing is required to be coated with lubricating grease during assembly due to its regular surface rolling arrangement and oil storage holes with helical Angle. It is especially suitable for the occasions where it is difficult to form fluid lubrication under high load and low speed. The oil storage holes on the surface can ensure the optimal oil distribution, and long-term maintenance is unnecessary.

VIIPLUS 20 series POM BUSHINGS has good physical & mechanical properties, also has certainly chemical properties. This material has good machining performance if required.tri-layer low maintanence plain bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after rolling process completed. Lubrication indents are stamped into this layer.

POM composite plain bearings are available as straight bushings, washers and strips

Advantages of VIIPLUS POM composite plain bearings

include:

• maintenance-free operation

• very good frictional properties

• high load carrying capacity

• high sliding velocity

• small operating clearance

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.

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.

• 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.

1. POM thickness 0.30~0.50 mm. It provides high wear resistance 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.
