For the steel work should include: water should always be exposed to bearing surface, fouling, etc. to be cleared, and check bearing loose and corroded anchor bolts and appropriate effective rust treatment, the surface of steel parts paint, rollers and the rotating part of the rocker shaft from the top scrub and smear oil, basin-type spherical bearing stainless steel surface cleaning and inspection skateboard tetrafluoroethylene surface exists grease lubricants to dry and so on. Only jacking inspection and maintenance to ensure the seat is in proper working condition. The purpose of bearing maintenance work is required in order to maintain the bearing function, plan and implement maintenance management division bearing important daily work, bearing inspection work must be carried out according to plan in accordance with the purpose and frequency of inspection to check the contents of . By examining changes in seismic ball bearing supports, if necessary for repair and replacement to make timely and appropriate judgment, alongside perfusion will do from design to construction and other treatments Party shall maintain detailed management plan. Supports bi-directional sliding detect seismic design and production of ball bearings, bearing accurate information applications simultaneously detect changes in their performance and to put forward opinions change according to its causes, is to keep the bearing grace to your normal work important daily work. Inspection generally include routine testing, periodic inspection and found a detailed inspection of the railway bridge bearing change the type and cause of deterioration, bearing deterioration classification, according to railway standards, bearing deterioration of steel grade is divided into four seismic abcd ball bearing manufacturers, railway bridge bearing deterioration rating, according to railway standards, deterioration of steel bearing ball bearing seismic rating grid finished, laminated rubber bearing deterioration rating shows, pot bearings deterioration rating. Assessment methods railway bridge bearing deterioration, according to railway standard provisions bearing deterioration evaluation method made two provisions, to determine the type of bearing deterioration and degradation level, should be bright jumped ah fiber with the naked eye and under appropriate detection equipment inspection. How to deterioration of the project, at the time of rating, one of the most serious deterioration should be assessed. Deterioration and repair of the seat is determined, the deterioration or damage to the holder and the urgency of the inspection method of repair and the like. Word has different requirements for all countries, as a reference to the poor quality of determining the relevant standard bearing deformation and repair information, bearing a bridge interchangeable parts, especially the rubber bearing, due to the aging of its life than material concrete, steel side, at the discovery of the fault and the damage be repaired or even worse turn. Establish regular replacement refers again. Hao-engineered rubber, steel ball bearings seismic grid finished, seismic steel ball bearings provided by Hao-engineering rubber.
