First, the introduction of products
Isolation ball bearing is composed of a top plate, bottom plate, spherical liner, concave spherical liner, wear plate, flat wear plate, shear, shear pins, shear bolts and other components. The structure and ordinary ball type bearing, bearing capacity for vertical bearing capacity of the level of 20%.
Two, product features
1) its spherical liner with hard chromium plating, it has high wear resistance and low friction coefficient, improves the performance of bearing;
2) shear block, composite shear pin and shear bolts used in the design of more than horizontal bearing capacity, shear pin and shearing bolt is cut off, the one-way bearing into multi support, to avoid further damage to bearings, shock absorption, isolation, without support replace, reduce losses;
3) wear resistant plate using modified ultra-high molecular weight polyethylene, to meet the needs of the large carrying capacity also has a good wear resistance;
4) the bearing inherits the good performance of the general ball type bearing, it is not limited by the use of the environment temperature, and is suitable for a wide range of application.
Three, product application
Isolation sphericalbearing strictly enforce the technical conditions of People's Republic of China national standard GB/T 17955-2009< ball type bearing ", also referring to the European Committee for Standardization Technical Committee CEN/TC 167 August 1993 promulgated draft structure support standard seventh" ball type and column type poly four vinyl fluoride bearing "and second" slide ", the British standard BS 5400< steel bridge, concrete bridge and bridge combined with the provisions of article ninth >" bridge bearings ".
Our company through independent R & D and production of NKQZ3000 ~ 75000KN isolation sphericalbearing. Has been successfully applied to the Benghe bridge, Xiangjiang bridge, Chongqi bridge, Nanjing bridge and other four large and medium-sized domestic bridge engineering.
