General Description	N/A 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	N/A 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	N/A 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.
