Introduction

Tungsten steel bush is mainly used for stamping and drawing aspect, the device is to protect a class of components, depending on the demand, the product will have a different approach. Use bush, can effectively reduce the wear and punch or bearing between devices, and to achieve a guiding role. In terms of stamping dies, tungsten steel bush because wear, good finish, without frequent replacement, so as to achieve a higher utilization of equipment and personnel, and is widely used; stretching terms, mainly because some pieces of copper, stainless steel stretching pieces, because the frequency is too high, easy to heat, resulting in wear bush so that the red needle moves, poor appearance of the product size product errors, and products. Customers are advised to try a selection of tungsten steel bush, to avoid the above-mentioned drawbacks. Zhuzhou tongda can provide high-quality tungsten steel liner sleeve, bore and cylindrical mirror surface finish are high dimensional accuracy, vertical well, enjoy a higher rating among customers.

Tungsten steel bush works:

Tungsten steel bush after use and it is in contact with the surface to wear bush, protection and its contact surface wear to a certain extent, be replaced. Tungsten steel bush using a wear-resistant material in contact with the surface friction bush is generally a soft material, the friction when there is a certain avoidance and wear bush wear-reducing materials, reducing the shaft and bore wear, is a sliding bearing. bush can be replaced several times, extend the life of the body.

select tungsten steel bush there are several issues to consider:

1, the contact material properties include: surface roughness, hardness, material itself Properties
2, bush work environment: load, temperature, velocity, etc. bushing wear and other requirements of life are relative, not only depend on the bush itself, but depends on the material properties and bushing contact, even the best bush material if it is in contact with the material and hardness is low, the surface is very rough, very easy to wear out, and the other is generally used for low-bush, after all, is sliding friction, unless carrying very small, the speed is too high will produce a lot of heat, and no one too much.


Superiority of Tungsten Carbide Bush

Superiority of tungsten carbide bush(OD/6~450, ID/8~400, H/2~225) :

1. Used for water pump, oil pump and other pumps, especially used for high pressure or corrosion resistance pumps. 
2. Good wear resistance 
3. Keeping operation precision, prolong the lifetime of rolling axletree. 
4. Good materials, perfect performance, high machining accuracy.
5. Various types and grades, supplied as required.

Material: Tungsten Carbide 
Feature: - Excellent abrasion and wear resistance
- Excellent corrosion resistance
- High thermal conductivity
- Low coefficient of thermal expansion and friction
- High hardness
- High quality

Specification of Tungsten Carbide Bush

Our tungsten carbide bush, which has good wear resistance, high machining accuracy and nearly perfect performance, are widely used in water, oil and other high corrosion and corrosion resistance pumps.

The specification we can make is OD 6~ 450, ID 8~ 400 and H 2~ 225 mm.We can make various tungsten carbide bushes with complicated shapes. Either blanks or finished products can be provided.

There are many tungsten carbide bush specifications and grades. Zhuzhou tongda may also supply according to your prints, but if we have no moulds you should prepay the mould charges, when you get to a certain quantity, we will return the charges as a payment.

Tungsten Carbide Bush Applications

Tungsten carbide bush applications is widespread, the high flexibility of use.Generally speaking tungsten carbide bush is a device to protect a class of components. It is in the actual work and the role and purpose of its application environment have a great relationship. Valve applications, bushings be installed in the valve stem cap trap, in order to reduce the valve leakage, to seal; bearing applications, the use of bush to reduce wear between the bearing and the shaft seat, avoid the gap between the shaft and the hole increases and so on.

Tungsten carbide bush production and processing of high-strength, can withstand prolonged load, with high chemical stability, alkali, alcohol, ether, hydrocarbons, acid, oil, detergent, water (sea water), and has no smell , non-toxic, tasteless, non-rust characteristics, its widely used in alkali corrosion, environmental health, food, textile and other aspects of mechanical components provides excellent conditions for use.

tungsten carbide bush role:
1. simplified maintenance of the machine, saving labor, excellent mechanical cutting performance, improve labor productivity;
2. good elasticity, can be bent without distortion, while maintaining toughness, resistance to repeated impact;
3. wear and self-lubricating, carbon steel provides superior cast bronze and phenolic laminate performance in the absence of oil (or butter oil) lubrication applications, reduce consumption, energy saving;
4. suction noise, vibration, MC nylon molding metal is much smaller than that of vibration attenuation, provides practical ways superior to metal to prevent noise;
5. compared with metal tungsten carbide bushings, MC nylon low hardness, no damage to the grinding parts;
6. low mc coefficient, provided its wide application in friction possible.
