ZTQZ Series Spherical Rotation Bearings

The upper hinge of the bearing adopts a super-large spherical surface with hard chrome plating, providing high wear resistance and low friction coefficient, thereby enhancing the performance of the bearing. The lower hinge combines a super-large spherical surface with a spherical wear-resistant plate, allowing for a vertical curve rotation of 0.04 rad and a horizontal curve rotation of 360 degrees, ensuring flexible rotation. The wear-resistant plate is made of modified ultra-high molecular weight polyethylene, meeting the needs of high load capacity and excellent wear resistance. The bearing is not limited by environmental temperature, making it widely applicable. The lower hinge is equipped with a vibration hole to meet the needs of large-volume concrete construction. The pin shaft and wear-resistant plate work together to prevent the "jamming" phenomenon during beam rotation construction. It can meet the needs of various cross-line bridges and interchange bridges for cast-in-place beam prefabrication construction, without closing or stopping the crossed lines, providing high social and economic benefits.

Other Products

Lasso shock-absorbing support

In normal use, the support moves within the range of designed displacement, the cable does not play a limiting role, and the cable damping support is the same as the conventional support.

LRB highway bridge lead core seismic isolation rubber bearing

The highway bridge lead core seismic isolation rubber bearing is a standard bridge component product developed in accordance with national and industry-related standards, while also referencing European standards. This product is available in two types: rectangular and circular, suitable for various highway and municipal bridges in seismic zones of 8 degrees and below.

GKPZ(Ⅱ) Seismic Rubber Bearing

The GKPZ type bowl rubber support consists of an upper seat plate, a lower seat plate, a middle steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, an SF-1B composite plate, a stainless steel plate, a damping rubber ring, and a shock-absorbing plate. The supports are divided into 31 specifications based on vertical load capacity, ranging from 0.8MN to 60MN. Its structure is consistent with that of ordinary bowl rubber supports, with the addition of damping rubber rings and shock-absorbing plates, providing good seismic and shock-absorbing performance. The horizontal load capacity of the unidirectional movable support and fixed support is 20% of the vertical load capacity.
