Ball bearings are usually divided into non-drinking stiffening stiffening bracket bearing two kinds. Only one non-stiffening rubber bearing, although under horizontal force horizontal deformation of rubber bearings to meet the needs of shearing, but bearing in vertical loads tend to produce vertical deformation. At this point, the ball bearings due to constraints is relatively small, and because the rubber ball grid incompressibility steel bearing, ball bearing deformation only sideways expansion, there will be a large convex around the drum at its elongation greater rubber oil, thereby generating stress aging. Such ball bearing on our roads and bridges is not recommended. In order to withstand large vertical loads can also meet the needs of horizontal displacement, the bridges are generally used stiffened laminated rubber bearings, ball bearings stiffening stiffening material can be steel, glass fiber, cotton, nylon and other fixed ball steel bearings, single use of the bridge stiffening material for steel, other materials not recommended, since as a stiffening plate rubber under vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation correspondingly reduced, thus greatly improving the vertical stiffness of rubber bearings. Then the bridge steel ball bearings, ball bearings for vertical deformation of the total deformation of each thin rubber sheet combined. Currently in the domestic market can be seen as a type of repair grouting agents used more in the domestic manufacturers are also a large number, ball bearing supply should fully meet the needs of the project, in the purchase of a single ball bearing should be based on its key performance indicators and major requirements, purchase the actual needs and technical requirements for each type of product engineering is appropriate, ball bearings and such products are also constantly updating and development, and for the highway bridge support repair materials are constantly dedicated perfusion research and development, more and more species will be present such products, it is available for reference. Ball bearing walls BY series non-shrink grout. BY series of non-shrink grout walls, its main performance indicators steel ball bearings, used as anchor value tendons should pay attention to the major issues of the requirements of the hole quickly. Ball bearing technical specification of the product is to follow the former Ministry of Metallurgical Industry of construction requirements, so using BY series grout used products.
