Molded Isolation Bearings
MOLDING ISOLATION BEARINGS The following pictures will give you a better idea of the process of manufacturing isolation bearings. Norman J. Mason President, Mason Industries, Inc.
Spring Isolators
SPRING ISOLATORS Not all problems can be solved with rubber isolation pads. On page 2 we have indicated that the cut off point for rubber bearings is about 5.5 Hz. This would mean that the incoming frequency should not be lower than 16.5 Hz just to maintain the traditional but often unsatisfactory 90% theoretical efficiency.…
Introduction
Noise and vibration isolators are used to prevent the downward transmission of vibration from a machine to a structure, the upward transfer from the structure to a sensitive machine or to isolate a complete building from ground vibration. Ground vibration may be generated by above ground or under ground passenger or freight trains, or heavy…
