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 and washer only furnished by Lord.
All metal parts are made of low carbon steel.

  • 1 These ratings are for general industrial applications. For on-highway use 80% of loads shown. For off-highway use 70% of loads shown.
  • 2 If you require a high bolt torque series or any other special part, use metal bracket part number and the CBA part number, contact the application department for assistance.
  • 3 Bracket must provide support in excess of M Dia. Min., otherwise a washer is required. Washer must be ordered separately.
  • 4 Minimum supporting member thickness for high rebound load capacities.
  • 5 Maximum supporting member thickness for all applications.
