Track Roller Bearings Scroll mode down

Crawler roller bearings are a kind of rolling bearing, the spherical alloy steel ball is installed in the middle of the steel ring and outer steel ring, rolling way to reduce the power transmission process of friction and improve the mechanical power transmission efficiency. Crawler roller bearings can not withstand the heavy load, more common in light industrial machinery. Crawler roller bearings also ball bearings.

  The track roller bearing consists of four basic elements: a ball, an inner ring, an outer ring and a cage retain retainer, as shown. General industrial crawler roller bearings meet the AISI52100 standard, the ball and the ring is usually made of high chrome steel, Rockwell hardness (Rockwell C-scale hardness) between about 61-65.

  (Such as: medium carbon steel, aluminum alloy) or non-metallic (such as: Teflon, PTEF, polymer materials), and the hardness of the retainer is lower than that of the ball and the ring. The rolling bearing is smaller than the rotational frictional resistance of the journal bearing, so that the temperature at which the friction is generated is relatively low at the same speed.

Crawler roller bearings are generally used in low-load mechanical transmission equipment. Because the crawler roller bearing bearing area is small, in the case of high-speed operation is prone to serious mechanical damage, so the heavy load of mechanical transmission often take the needle roller bearings to increase the bearing surface, improve the mechanical transmission efficiency, While reducing mechanical damage.

Crawler roller bearings change the friction of the bearing, the use of rolling friction, this way more effectively reduce the friction between the bearing surface phenomenon, to enhance the life of the fan bearings, and therefore the radiator life extension. The disadvantage is that the process is more complex, cost-effective, but also bring higher work noise.

 When the surface of stainless steel pipe appears brown rust (point) when people were surprised: that "stainless steel is not rusty, rust is not stainless steel, steel may be a problem." In fact, this is a lack of understanding of stainless steel a one-sided error view. Stainless steel under certain conditions will be rusty. Stainless steel has the ability to resist atmospheric oxidation --- that is, stainless steel, but also in the acid, alkali, salt medium is the ability to corrosion - that is, corrosion resistance. But its corrosion resistance is the size of its steel chemical composition, plus the state, the use of conditions and environmental media type and change. Such as the 440c steel pipe, in the dry and clean atmosphere, there is absolutely excellent resistance to corrosion, but it moved to the beach area, in a large number of salt containing sea fog, will soon rust, and therefore not any Stainless steel, in any environment can be resistant to corrosion, not rust. Stainless steel is the surface of the formation of a thin layer of thin and strong and stable stable chromium oxide film (protective film), to prevent the continued infiltration of oxygen atoms, continue to oxidize, and the ability to obtain corrosion resistance.
