JQZ(III) 10DX Spherical Bearing JQZ Seismic Spherical Steel Bearing Contact Me for Quote

The JQZ series spherical bearing consists of an upper plate, lower plate, spherical wear plate, planar wear plate, spherical plate, rubber seal ring, guide rail assembly, and anchoring components. The bearing is available in 33 specifications with vertical load capacities ranging from 1.0MN to 70MN. Its structure, based on the conventional spherical bearing, utilizes modified ultra-high molecular weight polytetrafluoroethylene for the wear plates, offering excellent wear resistance and self-lubrication, thereby extending the bearing's service life and reducing maintenance and upkeep costs.

JQZ(I) Type: For fixed bearings and unidirectional movable bearings, the horizontal load capacity in the non-movable direction is 10% of the vertical load capacity. JQZ(III) 10DX Spherical Bearing JQZ Seismic Spherical Steel Bearing Contact Me for QuoteGenerally suitable for bridges in regions with peak ground acceleration Ag ≤ 0.10g;

JQZ(II) Type: For fixed bearings and unidirectional movable bearings, the horizontal load capacity in the non-movable direction is 15% of the vertical load capacity. Generally suitable for bridges in regions with peak ground acceleration 0.10g ≤ Ag ≤ 0.15g;

JQZ(III) Type: For fixed bearings and unidirectional movable bearings, the horizontal load capacity in the non-movable direction is 22.5% of the vertical load capacity. Generally suitable for bridges in regions with peak ground acceleration 0.15g ≤ Ag ≤ 0.20g;

For bidirectional movable bearings in all directions and the movable direction of unidirectional movable bearings, the horizontal shear check is designed at 5% of the bearing's vertical load capacity.

II. Product Features

1) The spherical crown liner plate uses a hard chrome plating process, providing high wear resistance and low friction coefficient JQZ(III) 10DX Spherical Bearing JQZ Seismic Spherical Steel Bearing Contact Me for Quote, enhancing the bearing's performance;

2) The bearing's vertical curve internal rotation angle is 0.02rad, while also adapting to any rotation angle within the horizontal curve, ensuring flexible rotation;

3) The wear plates are made of modified ultra-high molecular weight polyethylene, meeting the needs of high load capacity while offering excellent wear resistance and self-lubrication, extending the bearing's service life and reducing maintenance and upkeep costs;

4) Suitable for environmental temperatures ranging from -40℃ to +60℃, making it applicable in a wide range of regions;

5) The anchor bolts used in the bearing employ a Dacromet surface treatment process with high corrosion resistance, improving the bolts' anti-corrosion performance;

6) The bearing's friction coefficient is less than 0.03, and when combined with lubricating silicone grease, it significantly extends the bearing's lifespan.
