The vertical support of the roller shaft consists of an upper seat plate, a lower seat plate, rollers, a base, rubber plates, sliding plates, bushings, shafts, rocking seats, upper and lower pressing plates, and fixed plates. It has the functions of large displacement, large rotation angle, and vertical anti-lateral characteristics, making it suitable for bridge projects across large rivers, canyons, and seas.

The marine anti-corrosion spherical bearing is composed of an upper plate, a lower plate, a spherical crown lining plate, a spherical wear-resistant plate, a flat wear-resistant plate, shear blocks, shear pins, shear bolts, and an internal dustproof device. Its structure is consistent with that of ordinary spherical bearings, and the horizontal bearing capacity is 15% of the vertical bearing capacity.

The rotating support is composed of upper hinge, lower hinge, positioning framework, pin shaft, spherical wear-resistant plate, support system, etc. It is suitable for various types of cross-line bridges and cast-in-place beam construction on site for interchange bridges.

LYQZ spherical bearing is composed of upper seat plate, lower seat plate, self-aligning slider, concave liner, spherical crown liner, spherical wear-resistant plate, flat wear-resistant plate, pull-out bolts, upper and lower pressure plates, etc. It has the functions of large displacement, large angle, and vertical anti-lift characteristics, suitable for bridge projects across large rivers, canyons, and seas.

The wind-resistant bowl-type rubber support consists of an upper plate, a lower plate, a middle steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, a disc spring, a stainless steel plate, an adjustment plate, a retaining ring, and a transition plate. Its structure is consistent with that of a regular bowl-type rubber support, with the addition of a disc spring, adjustment plate, retaining ring, and transition plate, allowing for adjustable support height and excellent seismic and shock absorption performance.

The seismic isolation spherical bearing is composed of an upper plate, a lower plate, a spherical crown liner, a concave liner, a spherical wear-resistant plate, a flat wear-resistant plate, shear blocks, shear pins, shear bolts, and so on. Its structure is consistent with that of ordinary spherical bearings, and the horizontal bearing capacity is 20% of the vertical bearing capacity.

The highway plate rubber bearing uses a vulcanized combination of an intermediate steel plate and rubber, fully utilizing the energy absorption and dissipation properties of rubber. It has the advantages of high bearing capacity, significant shock absorption and isolation effects, and is easy to maintain and replace. It provides significant economic benefits while meeting the corner requirements of bridges. The application of plate rubber bearings has promoted the advancement of bridge technology in our country and has now become one of the main types of bearings for medium and small span highways in China.

The highway bridge plate rubber bearings strictly implement the provisions of JT/T4 - 2019 "Highway Bridge Plate Rubber Bearings" and JT/T663-2006 "Specification Series of Highway Bridge Plate Rubber Bearings." This product further optimizes its design parameters and structural types after summarizing the experience of various designs, manufacturing, and applications of plate rubber bearings in the past, and the comprehensive performance of the product has been further improved.

The GPZ (KZ) series seismic-resistant pot bearings strictly adhere to the JT/T 391-2019 "Pot Bearings for Highway Bridges" standard and are designed in accordance with the provisions of the European standard EN 1337.

The GPZ (II) type bowl-shaped rubber bearing 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, and a stainless steel plate. The bearings are divided into 31 specifications based on vertical load capacity ranging from 0.8MN to 60MN, with the horizontal load capacity of unidirectional movable bearings and fixed bearings being 10% of the vertical load capacity.

The GPZ (II) series pot bearings are designed according to the Ministry of Transport industry standard JT 391-2019 "Pot Bearings for Highway Bridges". This product is based on over twenty years of research and production application of highway pot bearings, referencing the standards and technologies of European and American pot bearings, and optimizing the GPZ series pot bearings.

JT/T391-2019 "Highway Bridge Pot Bearings", GPZ (2019) series pot bearings are the supporting drawings for this standard.
