The cheapest QZ Spherical Bridge Bearings

  QZ spherical bearing Description QZ spherical type bearing is by the upper support plate, lower support plate and spherical plate, PTFE slide board (F4, spherical PTFE) and rubber ring is composed of a special basin type rubber bearing products.It will be pot bearings of the rubber board change for spherical PTFE hence the name, because QZ  spherical bearings in the middle plate and the bottom basin also correspondingly changed into a spherical, reducing the friction coefficient.The displacement is realized by sliding between the upper support plate and flat PTFE.In the upper support plate, a guide groove or a guide ring is arranged to constrain the one-way or multi direction displacement of the supporting seat, and the spherical one-way movable bearing and the fixed supporting seat can be made.In order to meet the needs of bearing angle by sliding between spherical plate and spherical PTFE.   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 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.   Applicable temperature range a.Normal temperature type bearing: suitable for -25℃ ~+60℃ b.Cold resistant bearing: applicable to -40℃ ~+40℃   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 1000-20000KN 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.
