Overview
Rubber Bearing Plates are elastomeric structural components placed between a superstructure and its supporting substructure to transfer vertical loads while simultaneously accommodating horizontal movement, rotation, and vibration. They act as a flexible interface that prevents direct hard contact between concrete or steel elements, protecting both from stress concentration and surface damage.
KIDL supplies both plain rubber pads and steel-laminated elastomeric bearing pads engineered to international standards. Plain pads suit lighter loads and moderate movements, while laminated bearings — with alternating layers of rubber and steel — handle heavy axle loads, large rotations, and significant translational movement with exceptional precision.
From bridge bearing replacement to industrial machinery isolation, KIDL’s Rubber Bearing Plates provide the quiet, maintenance-free performance that keeps structures safe, stable, and silent for decades.

Advantages
Installation
1. Bearing Area Preparation
Clean the bearing seat surface thoroughly. Remove all dust, laitance, oil, and loose material. The seating surface must be level, smooth, and flat — permissible tolerance ±2 mm under a 3 m straightedge.
2. Levelling Mortar Application
Where the bearing seat is uneven, apply a thin layer of non-shrink epoxy or cementitious levelling mortar. Allow full cure before placing the bearing pad to ensure uniform load distribution.
3. Bearing Pad Positioning
Place the rubber bearing plate centrally on the prepared seat. Align precisely with the beam centreline and check plan dimensions. Do not drag the pad across the surface — lift and place to avoid displacement.
4. Beam Lowering & Seating
Lower the beam or superstructure element slowly and squarely onto the bearing pad. Confirm that the pad is fully covered by the beam soffit with no overhang beyond the design edge distance.
5. Load Verification & Inspection
After full load transfer, inspect the pad for uniform compression, no lateral extrusion beyond 10% of total thickness, and correct plan position. Record pad dimensions and condition in the QA log.
6. Protective Sealing (if required)
For exposed bearings in aggressive environments, apply an approved elastomeric sealant around the pad perimeter to prevent water ingress, chemical attack, and UV degradation over the service life.
