Product introduction

The Spring confined Pb rubber bearing (SPR) of Kawakin Core-Tech is the high damping rubber bearing by installing the lead plugs inside to the regular rubber bearing. In addition, the lead plug has enhanced deformability by the surrounding restraint spring, that useful to significantly improve for the recovery ability. The damping coefficient of the bearing product depends on the design and also the size of the bearing, however the damping coefficient of the bearing can reach 20%. Bearing deformation during an earthquake can reach 250% of the rubber layers total thickness inside the bearing.
