Free bearing allows rotation, longitudinal movement & transverse movements. The main components of a free bearing are the same as those of a fixed bearing, but are able to provide two-direction movements.PTFE is a well known polymer which possesses some remarkable properties. The coefficient of friction when sliding against a polished surface can be as low as 0.01 which compares with ice sliding on ice. In addition, its coefficient of friction is the lowest at highest specific pressures which make it particularly suitable for use in structural bearings.In order to minimize space requirements, Pot Bearings are designed for relatively high contact pressures against the structure. This also ensures lowest friction values. Most elastomers cannot sustain such pressures in their free state and must be effectively contained to prevent over straining. When constrained in this way, the elastomer behaves as a semi-viscous fluid and can safely accommodate useful degrees of angular displacement. All BEARING TECHNOLOGIES Pot Bearings can safely accommodate 0.01 radians rotation about any axis.

For railway bridges with spans in excess of 30.5m, where open web through girders are generally provided, the amount of movement needed and the vertical load transmitted through each bearing is too large to be catered by the sliding bearings. It is common, on Indian Railways, to provide rocker & roller bearings at the free end of open web through girders, and rocker bearings at the fixed end.

Our Spherical bearings designed in accordance with Bridge Design Specifications.The basic spherical bearing design is comprised of a convex base with a mating concave element for rotation. On expansion bearings, an upper sliding plate is added for translation. All contact surfaces are polytetrafluoroethylene (PTFE) to stainless steel.

Pin Fixed Bearing consisting of a metal pin provided within a metal cylinder to bear & transmit horizontal force along any direction in the horizontal plane and accommodating rotational movement about any axis.

Metallic guided bearing consisting of a sliding assembly with restraint along a desired direction to bears and transmit horizontal force and capable of allowing movement in a direction perpendicular to the direction of horizontal force.

Kanta Flexs elastomeric bridge bearings with simple reinforcement are made up of multiple elastomer layers separated by reinforcing steel plates moulded on the actual layers, and can be manufactured in a rectangular or circular shape to meet individual engineering requirements.
