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 Mount assembly only furnished by Lord Corporation
  • 1 Rebound Washer: Steel, zinc plated Mounts are designed to be loaded in the axial direction only. If bracket provides support equal to top rebound washer, Diameter A top rebound washer is not required.
