LORD Dynaflex® LCR Series Couplings are ring-type couplings developed to overcome numerous torsional problems associated with vehicular and industrial driveline systems. These easily installed couplings reduce noise transmission and increase bearing and driveline life through greater misalignment accommodation, isolation of low frequency disturbances, and isolation of torsional shock. These highly flexible elastomeric couplings for accessory drives are also designed to eliminate lubrication and maintenance.

Features and Benefits:
• Misalignment accommodation – elastomeric flexibility allows for large angular misalignment. For permissible misalignments, including axial and radial, Refer to Table 1.
• Vibration isolation – low torsional spring rate is achieved with the elastomeric ring-type coupling using rubber in compression. This allows for low system natural frequencies and isolation of first mode driveline disturbances in most driveline systems.
• Shock protection – isolates torsional shock, prevents backlash and protects system components, including bearings, from fatigue failure.
• Long service life – Dynaflex LCR Series Couplings have proven themselves under demanding service conditions.
• Maintenance-free – elastomer flexibility accommodates all motion without wear, eliminates the need for lubrication.
• Noise reduction – no metal-to-metal contact; elastomer attenuates structure-borne noise and isolates vibration from components that would act as noise generators.
• Systems Engineering – Parker LORD has in-house computer capabilities for multi-torsional analysis to assist in proper coupling selection.

Typical Applications:
Dynaflex LCR Series Couplings are useful for a wide range of rotary drive applications, from lawn and garden tractors to large construction equipment, including U-joint replacement.
