What is a  drop axle  on truck? A dropped axle is the axle of a vehicle that is bent upwards towards the ends, i.e. the centre is ‘ dropped ‘. Besides, what is a tag axle on a truck? A lift axle , or tag axle , as it is often called, is a  heavy truck axle  that is designed to be lifted off the road’s surface when not needed. A lift axle can be mounted on the truck , the trailer or both and is commonly found on tanker-style trucks as well as trucks used to haul over-sized loads. Secondly, which  axle  is the drive axle on a semi? The three axle truck tractor most commonly seen on US highways Has two rear drive axles and in normal conditions, the front drive axle is providing the force to drive the truck. In fact, only one wheel of that axle is actually moving the truck and trailer down the road. Secondly, how much does a drop axle weight? the axle assembly weights about 1500 lbs dead weight if your not going to be using it. Why do some trucks have wheels that don’t touch the ground? Th

A limit switch is a device that uses the collision of mechanical moving parts to make contact action to turn on or off the control circuit, thus achieving certain control purposes. It works in conjunction with other devices to form more complex automation equipment in industry. Therefore, choosing a more appropriate limit switch will make the whole automatic control system more reasonable and efficient. How to set limit switches Setting limit switches depends on the type and location of the limit switches you are using. The first thing you need to do is to determine where your limit switch will be located and what it will be used to detect. This will give you an idea of what size and what type of switch is needed. Once you have the correct  industrial limit switch , you will need to secure it in its position. A standard limit switch will have pre-drilled holes where the switch can be held in place by fixings. If you are installing a limit switch for the first time, you may need to dril

 High bulk density  graphite block  refers to block high-purity graphite, and high-density graphite is also called molded graphite. The specifications and physical and chemical indicators of the above products can be customized. High bulk density graphite block adopts advanced vibration forming process, after roasting or secondary roasting and graphitization process, the internal and external structure of the product is uniform. The products are widely used and can be used in mold processing, chemical heat exchanger processing, lithium battery cathode material preparation and so on. The production cycle of the product is 95 days. Characteristics of high-density graphite blocks The performance of high-density graphite blocks is relatively excellent. High-purity graphite, a material, has made an indelible contribution to the development of the chemical industry. 1. Corrosion resistance 2. High temperature resistance, the melting point of graphite is 3850 degrees, and the boiling point is

  Power Steering Oil Seal   Power steering system is one of the major and indispensable systems in automobile. Power Steering Oil Seal can prevent pressure loss in the power steering gear and maintain normal pressure. Make sure that the steering of the power steering wheel works normally, and the reciprocating crankshaft operates normally. Furthermore, with the value-added power steering seals in use within the steering system, it provides prevention of leaking steering fluids and retains fluids inside the machine so the steering system can operate properly and avoid malfunction.   Types of Power Steering Oil Seal   We provide power steering seal for reciprocating rack shaft and rotary steering shaft both with high quality and excellent performance in sealing hydraulic fluids to keep the system running.   1.Rotary Power Steering Oil Seal   Rotary power steering oil seal is installed on the rotating shaft to prevent oil leakage and maintain lubrication and ensure normal steering functio

  Bone china The basic process is to use animal bone charcoal, clay, feldspar and quartz as the basic raw materials, after high-temperature firing and low-temperature glaze firing twice to produce a porcelain. Bone china has two basic characteristics, one, a bone charcoal content of 36% or more (national standard), and two: it is made by a second firing (plain firing, glaze firing). According to the British standard for bone china, it contains 30% tricalcium phosphate from animal bones and the finished product is translucent before it can be called bone china. New Bone China Unlike bone china, the word china is not usually added to the name. By adding calcium oxide, a mineraliser with a similar composition to bone powder, to the traditional firing temperature, deformation, water absorption and translucency of porcelain, a new material is formed that is similar in appearance to bone china and better in quality than bone china. Thus, the astute manufacturers gave a name to the  new bone

    Infrared lenses have low power supply and use two types of infrared rays: near-infrared or short-wave infrared, with a wavelength of 0.76-1.5 microns, which penetrates deeply into human tissue, about 5-10 mm; far-infrared or long-wave infrared, with a wavelength of 1.5-400 Microns are mostly absorbed by the superficial skin, and the depth of penetration of the tissue is less than 2 mm. Enhanced nighttime image capture. Therefore, most users need infrared cameras to pursue strong camera effects. The basic principle of infrared lens: Ordinary film cameras can also take infrared photography, but they must be equipped with special infrared sensitive film and infrared lenses. The CCD/CMOS sensor used in the infrared lens can sense infrared rays. In order to ensure normal shooting without color shift due to infrared interference, camera manufacturers are equipped with ICF in front of the CCD to block infrared rays and pass visible light; the opposite of ICF, infrared The role of the lens
