Product Description

Introductions of spherical bearings:
 
Spherical bearing force transmission is reliable and rotation is flexible, it not only has pot rubber bearing capacity, allowable bearing displacement and better adapt to support angle, has the following advantages compared with the pot bearings: 
 
(1)Spherical bearing transfer force through spherical face, necking phenomenon does not appear, the reacting force in the concrete is relatively uniform. 
(2) Spherical bearing by sliding spherical PTFE plate to achieve the support of turning process, the small rotating torque, and rotational torque is only related to the friction coefficient of the spherical bearing and radius of spherical, has nothing to do with the rotating angle of bearing size. Therefore, it is especially applicable to the rotation angle, the design angle up to 0.05rad. 
(3) The rotation performance of the bearings is consistent, which is suitable for wide bridge and curved bridge. 
(4) Bearing without rubber bearing pressure, there is no effect on the performance of rubber aging rotating bearings, especially with the low temperature area.

Bridge bearings and expansion joint are important parts of whole bridge components,  but the amount money that spent on bridge bearing and expansion joint is only 2-3.5%, it is absolutely a wise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs.





Some typical spherical bearing types
QZ spherical bearing characteristic
QZ spherical bearing has great bearing capacity,large displacement and large turning angles, so it is more suitable for wide bridge and curved bridge.No rubber is used in the spherical bearings for bridge,so it never happen that brittle rubber caused by low temperature affecting the bearing rotation,and bridge spherical bearing is especially suitable for cold areas.

Advantage of QZ spherical bearing
1. The spherical rubber bearing can not force the shrinkage neck phenomenon, and the  reaction force on the concrete is relatively uniform;  
2. Spherical bearing by sliding spherical PTFE plate to achieve the support of turning process, the small rotating torque, and rotational torque and is only related to the coefficient of friction of the spherical bearing radius and Teflon plates, has nothing to do with the bearing angle, especially suitable for the requirements of high angle, corner design up to 0.05rad;
3. The QZ spherical bearing is consistent with the anisotropic rotation performance, which is suitable for wide bridge and curved bridge;
4. The bearing products do not have rubber bearing, and there is no influence of rubber aging on the rotation performance of bearings, especially suitable for low temperature regions.

Classification of QZ spherical bearing
QZ spherical bearing is subjected to vertical load and rotational kinetic energy, and the horizontal displacement characteristics are classified according to their horizontal displacement characteristics:
1. One-way movable QZ spherical type bearing: bearing the one-way horizontal load, with 
  the longitudinal displacement performance, code ZX;
2. Two way movable QZ spherical bearing: with multi direction displacement performance,  
  code DX;
3. Fixed bearing: under horizontal load, no displacement, code GD.

High Quality Spherical Rotating Steel Bearing to Leabanan

Technology performance
1. The rotation angle of the support is divided into 0.01,0.05 and 0.02rad, which can be increased according to the requirement.
2. The vertical bearing capacity of 1000-200000KN is divided into 16 levels, and the bearing capacity of the bearing is 10%.
3. Coefficient of friction: Normal temperature type μ≤0.03; Hardy type μ≤0.05.
4. Displacement of bearing design:
  a.bridge in axial direction: ±50,±100,±150mm
  b.transverse direction of bridge: ±20mm
  The design displacement can be changed according to the engineering requirements.



Function of QZ spherical bearing
QZ spherical rubber bearing is through the spherical force, has no force of the phenomenon of shrinkage, the role of the anti force in the concrete is more uniform;QZ spherical type bearing by sliding spherical PTFE plate to achieve the support of turning process, the small rotating torque, and rotational torque and is only related to the coefficient of friction of the spherical bearing radius and Teflon plates, has nothing to do with the bearing angle.So it is especially suitable for the requirements of large angle, the design of the rotation angle of up to 0.05rad above.The rotation performance of bearings is consistent, and it is suitable for wide bridge, curved bridge, and so on. The bearings do not have rubber bearing. There is no influence of rubber aging on the rotation performance of bearings, especially in low temperature regions.
