Product Description

Turntable bearing, also calls the pivoting support, is one kind can simultaneously withstand the big axial loading, the radial load and the overturning moment large-scale bearing. The turntable bearing has the installment hole, the annular gear or the external gear, the oil passage and the packing assembly generally, can thus cause the main engine structural design to be compact, the guidance is reliable, the maintenance is convenient. turntable bearing whether there is teeth-formula, external tooth type and internal tooth-like four contact ball bearing, two-row angle contact type ball bearing, overlapping cylindrical roller bearing, overlapping circular cone roller bearings and three row of cylindrical roller combination bearing and so on many kinds of structure patterns. And four contact ball bearings have the high static load capacity; The overlapping cylindrical roller bearing has high moves the load capacity; The overlapping circular cone roller bearings through pre-full have been able to enable the bearing to have the big supporting rigidity and the high rotation precision. the turntable bearing widely applies in the hoisting machinery, the mining machinery, the construction machinery, the harbor machinery, the ships machinery as well as the high accuracy radar machinery and the missile launcher and so on the large-scale turning gear.
