Description of  Long Serve Time Rubber Bearings          
       Long Serve Time Rubber Bearing is sulfurized and stuck gether by several layers of rubber sheet and thin steel plate. It has sufficient vertical rigidity, and can reliably transfer the counterforce on the upper structures to pier platform; it has fine elasticity, and can adapt to the rotation of beam end;  Long Serve Time Rubber Bearing has great shearing deformation capacity, and can satisfy the horizontal displacement of the upper structures.

     Adhere a layer of 1.5mm to 3mm thick polytetrafluoroethylene plate on the surface of the above Rubber bearing,
and polytetrafluoroethylene sliding Tetrafluoro plate Bearing is formed. Besides vertical rigidity and elastic deformation,
able to endure vertical load and suit to the rotation of beam end, the beam end can freely slide on the surface of the
tetrafluoro plate due to the low friction coefficient of the polytetrafluoroethylene plate, and the horizontal displacement is
not limited; it specially suit to bridges with medium or low load and large displancement.

      Long Serve Time Rubber Bearings not only has fine technical performances, but also has simple structure, low price, no maintenance, easy to change, buffering and shock is isolating, low building height, and other characteristics. Therefore, rubber bridge bearing is welcomed and widely used in bridges.

 Aplication of  Long Serve Time Rubber Bearings     
     1.  Long Serve Time Rubber Bearing suits to bridges with span less than 30m and small displacement. Different
flat shape suits to different bridge span structures: orthogonal bridges adopt rectangular bearing; curvilinear bridges, obique crossing bridges and cylindrical pier bridges adopt circular bearing.

      2.Tetrafluoro  Long Serve Time Rubber Bearing suits to bridges with large span, several spans in continuous,
with simply supported beam and continuous plates strutures, and large displacement. It can still be used as the sliding block in pushing of continuous beam and cross sliding of T-shaped beam. The application of rectangular and circular tetrafloro  Long Serve Time Rubber Bearings are the same with rectangular and circular general rubber bearing,separately.

Classification and representation methods of  Long Serve Time Rubber Bearings

     b.Tetrafluoro sliding plate type neoprene bearing

The operating principle of  Long Serve Time Rubber Bearings

       The main function of Neoprene bearing is reliably transfer the counterforce on the upper structures to pier platform,
and meet the need deformation of beam body ( horizontal displacement and rotation). It has sufficient vertical rigidity so
that can guarantee the lesser deformation of bearing in the effect of maximum vertical load. It has fine elasticity at
horizontal direction, and can adapt the horizontal displacement due to the effects of braking force, temperature,
contraction of concrete, creep and load, and at the same time, it can adapt the rotation of beam end.

Benefits:

• Strong and hardwearing construction, manufactured using quality rubber compounds.
• Quick and easy to install,
• Superior wear life, crack and cut resistance.
• Minimises operating surface damage with reduced impact levels.
• Excellent noise and vibration reduction.
• Increased traction.
• Enhances working life of steel tracks.
• Easy interchangeability between rubber and steel dependent on site conditions.
