Summary

• KLQZ range of spherical bearings are a new type of support suitable for large-span spatial structures. This type of spherical bearing has added tensile bearing capacity on the basis of GQZ series spherical bearings, has a compact structure, is easy to install, and can work well with the upper structure.

• Laser cutting / CNC machining /painting/ Assembly /pressure testing

• Very high producing rate

• Professional team & exquisite workmanship

• Considerable after sale service

• Excellent dimension rate

• Very competitive price

Application

KLQZ tensile ball bearings are mainly used in large bridges and large-span spatial structure engineering that require extremely high structural safety and stability.

Large span and special bridge types: widely used in large-span bridges, wide bridges, curved bridges, cable-stayed bridges, and ramp bridges. The structural stress of such bridges is complex, and the bearings need to adapt to displacement and rotation in multiple directions simultaneously

Large span and extra large span spatial structures: such as roof structures of large sports venues, exhibition centers, airport terminals, and other buildings. These structures have a large span, light weight, and are sensitive to wind and earthquake loads. KLQZ bearings can well meet their requirements for universal bearing and universal rotation

Features

Pulling resistance: able to withstand huge vertical pulling forces, which is crucial for solving negative reaction problems that may occur in curved bridges or large-span structures

Excellent seismic performance: Its strength and ductility are designed to be higher than the structure itself, making it a "safety valve" in strong earthquake zones, ensuring that "large earthquakes do not collapse"

Adapt to complex deformations: universal rotation and sliding ability, able to adapt well to structural displacement and rotation caused by temperature changes, vehicle loads, etc
