Product Description

Solid Bronze Metallic Self-lubricating Spacer Plug Graphite Flang  | VSB-50W

Cast Bronze Gasket Bearing Solid Bronze Washer

Copper Bronze alloy inlaying solid self-lubricating bearing lubrication, combined with copper alloy wear resistance and self-lubricating properties of solid lubricants, in the use process without refueling maintenance.

 

 

Products are widely used in high load, swing or intermittent movement, such as vehicle production lines, water turbine, reservoir work/accident door, plastic machinery, etc. According to the using condition, VIIPLUS can provide various types of copper alloy.

 

Oilless bearings have been developed for high load, low speed applications and are made of rotational cast high-strength bronze using a specially formed graphite plug as lubricant.

 

Plain Bearings bearings have been developed for high load, low speed applications and are made of rotational cast high-strength bronze using a specially formed graphite plug as lubricant.

 

Our VIIPLUS plain bearings are available in metric and imperial sizes from stock. Our in-house machining service is able to produce non-standard sizes to suit specific customer requirements.

 

VIIPLUS range of oilless bearings are the perfect solution for projects where lubrication cannot easily be provided or where conventional lubricants may carbonise. The design of oil feeding systems is time consuming and expensive

- The use of our oilless bearings can greatly reduce costs of maintenance and oil as it removes any need for such a system.

TYPICAL APPLICATIONS

  • Kilns

  • Dryers

  • Injection moulding machines

  • Dust collectors

  • Louvres

  • Hot conveyors

 

CHARACTERISTICS



VSB-50W WASHER Thrust washers PAW

 

1. May work without any ol for long period

2. Extremely high load capacity, good anti-wear and lower friction

3. Particularly appropriate for low speed and high load

4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed

5. Good chemical resistant and anti-corrosion characteristics

6. Can b€ used in wide range of temperature from -40℃-+300℃

STRUSTURE

 

VSB-50W WASHER material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.

Bearing forms made to order: standard forms in special dimensions, thrust washers, flanged thrust washers, half-bearings, special shapes obtained by stamping or deep drawing, customized bearing designs

 

VIIPLUS  oilless bearings benefit from outstanding chemical and corrosion resistance. The lubricant used in these bearings is formed from abrasion resitant materials (such as graphite, PTFE etc) and has a stabilised molecular structure.

These oilless bearings are suitable for dry environments where contamination is a risk, wet applications where there is high humidity and applications where the bearing is in an inaccessible location. VIIPLUS Oilless bearings are lubricated for life!

Please feel free to get in touch with our technical to ascertain which would be the most suitable combination to suit your application.
