1. Outside diameter: ring gauge pass (GO) and stop (NO GO) mode is adopted. The through end of ring gauge is the maximum size of outside diameter, while the end of ring gauge is the minimum size of outside diameter.
2. Inner diameter: press the shaft sleeve into the reference hole (H7 median tolerance) and test the shaft sleeve with cylindrical plug gauge. The through end of the plug gauge is the minimum size of the inner hole of the shaft sleeve, and the end end of the plug gauge is the maximum size of the inner hole of the shaft sleeve.The accuracy grade of the inner hole of the rolling shaft sleeve is H9.
Ring gauge and plug gauge size according to DIN1494 part I.
 

 
In the 1960's Glacier of the UK invented the steel-backed, sintered-bronze PTFE lined DU bearing. Like the DU bearings our VIIPLUS VSB Steel Backed Bushing are also used in dry, semi lubricated enviroments. It can substitute a conventional bearing where saving space is desired. The VIIPLUS VSB Steel Backed Bushing provides superior shock and impact load resistance. The Steel Backed PTFE Lined bushing maintains a low coefficient of friction and is usable without lubrication at high load, low speed operations with excellent wear resistance.

APPLICATION

It has a wide applicable temperature range from -319 degrees F to 518 degrees F. The thin walls and
lightweight construction enable a compact design of the product.The Steel Backed Bronze Bushing is used in a variety of applications in a number of industries. Below are a few of the more common uses:

How to choose the gear pump shaft sleeve bushes?

VIIPLUS Main production gear pumps shaft sleeve bushing sliding bearings.
Gear pumps in operation in the event of unusual noise, it should immediately check stands.
The gear pump sleeve bushings the selection principle is not high demand, for the occasion, but by experience, not to replace gear pump sleeve bushings timely selection.If the first gear pump operation, or long-term idle after use, preferably in small load or no-load circumstances running One hour.
At the beginning of operation, to gear pump within the shell filled with liquid to be delivered, for safety launch.The quality and capability of gear pump bushing affect the characteristics of gear pump machines directly.
The pump bushing out of the shackles of traditional design, making gear pump bushings in the design, production and use into a new area.By using viiplus gear pump bushings, production efficiency and product quality can be improved and production cost can be reduced in the processing and repairing. viiplus gear pump bushings Oil-free bearing maintenance-free
 

Detailed Information Boundary lubrication lead-free bearing is improved on the basis of VSB-20.

 
It has the same performance as the VSB-20, but the surface does not contain lead, and the field of use can be extended to areas with environmental requirements.

Self Lube Bearings Product Category SF-2 Boundary Lubricating Bearing

1. Marginally lubricated bushings for grease or oil lubricated applications

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

3. Optimum performance under relatively high loads and low speeds

4. Suitable for linear, oscillating and rotating movements

5. 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 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.
