General Description
Center Bonded Mounts provide flexible suspension systems for mobile, transport-mounted or portable equipment. Typical applications include engines, cabs, fuel tanks, pumps, air conditioning units, compressors and industrial machinery.


Application Engineering Assistance
Frequently, vibration isolation problems require a system engineering analysis. Lord has the computer capability, as well as specialized programs, for analyzing engine/ transmission combinations. The output from this analysis is a mounting proposal which optimizes performance over the complete range of operating speeds. This service is available to you upon request.


Note
Mounts and washers only supplied by Lord.
In applications where the mounts will be immersed in oil, parts made in oil-resistant elastomer are available. Contact Lord Corporation for additional information.
