HTB-31 is a new product inlaid with solid lubricant on the base of high-power brass, which breaks through the limit of ordinary bearings relying on oil film lubrication. It is suitable for use under high temperature and high load, corrosion resistance or failure to add oil. Its hardness is twice as high as that of ordinary copper sleeves, and its wear resistance is also twice as high. Currently widely used in metallurgical continuous casting machines, steel rolling equipment, mining machinery, ships, steam turbines, injection molding machines and equipment production lines.
HTB-32 is mainly suitable for low load, high temperature and medium speed applications, such as fireplace door hinges. Rim furnace raceway, light industry machinery, machine tool industry, etc.
The internal material of HTB-33 is the same as HTB-32. In addition to the function of HTB-32, it also reflects the cost savings, improves the compressive strength, and can be welded and installed on the end face and the substrate. It is suitable for construction machinery. Non-lubricated parts in metallurgical machinery and conveying machinery.
HTB34 is a typical material-saving product. In places where the mechanical performance requirements are not very high, it can be used as an alternative material for HTB-34, which can greatly reduce the cost and meet the requirements of use, such as: mold guide post, injection molding machine frame, etc.
HTB-35 is a reinforced product, which has extremely high compression resistance, and is especially suitable for the supporting parts of hoisting machinery, such as excavator support, hoist support, crane support, etc. However, because the substrate is made of steel, it is not suitable for use in water, acid or alkali.
