Our roads and bridges using a ball bearing hinge experienced during the execution of the standard, in 2007 began to standard technical specifications were revised again, the ball bearing hinge series of specifications have to do some changes, from our roads and bridges pot bearings The development, its adaptability corner from the maximum angle position 0.001rad GPZ development GPZ (II) the maximum angle position 0.02rad, ball bearing hinge maximum carrying capacity also increased from 50000KN to 60000KN, the situation is also true of China's railway . Here is the client in order to understand the use of the GPZ and GPZ (II) Basic Specifications Series listed for reference purposes only. Ball bearing hinge damping according to the current standard fixed ball bearing hinge finished, press the bearing temperature range of adaptation into room temperature type and cold type two, by the use of performance is divided into two-way bearing activities, southeast bearing activities and three types of the fixed bearing. Ball bearing hinge series of specifications, technical performance GPZ, the ball bearing hinge vertical angle of not less than 0.001rad, vertical bearing capacity of 1000 ~ 50000KN divided into 28 horizontal bearing capacity of the non-slip surface is vertical 10% of the friction coefficient in the desired pattern classification. Matters must be special attention before painting before painting the basic surface to be coated must be processed to reach the ball joints smooth surface fixed bearing manufacturer, is the key to ensure the coating quality. Otherwise, due to the substrate surface is not smooth, retained harmful substances, ball bearing hinge will seriously affect the adhesion of the coating, the coating peeling off prematurely and lose its protective effect. That is carried out prior to painting to perfect surface treatment, to enhance coating adhesion, better play the role of coatings to protect fixed ball joint bearing, extend its life, plays an extremely important role. Ball bearing hinge protective effect is good or bad, it was considered one-third coatings, construction of six points, the extent of the visible surface treatment and fine construction directly affects the protective effect, according to the experiences, the basic surface treatment include the following. General use of organic solvent degreasing degreasing, chemical degreasing fixed ball joint bearing manufacturers, ball bearing hinge electrochemical degreasing and emulsifying cleaning degreasing and other methods. The most commonly used organic solvents and degreasing chemical degreasing. Ball bearing hinge is the use of chemical degreasing grease saponification occurs in alkaline medium were removed by saponification oil, it is also called hot alkaline degreasing method, this oil works best grid fixed ball joint bearing, fixed ball Hinge Bearing manufacturers provide free design deepen by Hengshui HaoTong Engineering Rubber Company.
