Spherical bearing is composed by top plate, base plate, convex middle plate and two Teflon plates of
different composition. Opposite the top plate, it is a concave spherical in the base plate, and the PTFE
plate between them. Beam rotation through spherical surfaces and PTFE plate sliding; stainless steel
plate on the top plate and another PTFE plates on the intermediate steel plate perform the second
sliding surface, realized beam stretching displacement produced by temperature factors.
Spherical bridge bearing transfers force reliably and rotation performance is consistent. Spherical bridge
bearing has great bearing capacity, large displacement and large turning angles, so it is more suitable
for wide bridge and curved bridge. No rubber is used in the Spherical bearing so it never happen that
brittle rubber caused by low temperature affecting the bearing rotation, and Spherical bearing is
especially suitable for cold areas.
1. spherical rubber bearing with spherical force, there will be no force of necking phenomenon, the effect on concrete reaction was homogeneous;
2. Spherical Bearing
by spherical teflon plate of the sliding bearing of the rotation process, rotational torque is small, and rotational torque and pedestal only spherical radius and friction coefficient of ptfe plate, has nothing to do with bearing Angle size, especially suitable for large Angle requirement, the design Angle of 0.05 rad.
3. QZ ball bearings to the same rotation speed, is suitable for wide bridge, curved bridge;
4. this kind of bearing products without rubber pressure, there is no rubber aging effect on the properties of bearing rotation, especially suitable for low temperature regions.
Features of Spherical Bearings
1.Allows for large displacement.
2.Accommodate larger rotations than pot bearing in excess of +/- 0.03 radians.
3.Unlimited movement capability in any directions.
4.Excellent self-alignment capability.
5.Minimum sliding friction coefficient.
6.Dimpled PTFE disc is fitted in 1/2 depth of the concave steel plate for higher load bearing capacity.
7.PTEF disc with cavities for containing lubricant to reduce sliding friction.
8.Complying with BS EN-1337, KS4424, AASHO, ISO or other custom standards.
9. Easy installation.
10. Low cost maintenance.
