Lovejoy 68514411724 Rubber Insert

The Lovejoy 68514411724 is a standard-duty L110/AL110 jaw coupling spider engineered for reliable power transmission in HVACR and industrial pumping applications. This NBR elastomeric spider (Nitrile Butadiene Rubber), also referred to as a SOX rubber insert, features a solid center design that provides the highest level of stability for standard shaft-to-shaft spacing. With a Shore hardness of 80A, this insert excels at dampening torsional vibration and absorbing shock loads, protecting critical motor and driven equipment components from premature wear. Designed for high-speed operation, it supports up to 5,000 RPM and can accommodate 1 degree of angular misalignment and 0.015" of parallel offset. The Nitrile material is specifically selected for its oil resistance and performance in environments exposed to moisture and grease, maintaining structural integrity across a temperature range of -40°F to 212°F. As a fail-safe component, this Buna-N coupling insert ensures that even if the elastomer reaches its service limit, the jaw hubs will remain engaged to prevent complete power loss in critical systems.

Key Benefits for Contractors

  • High vibration dampening: The 80A durometer NBR material reduces system resonance, extending the life of bearings and mechanical seals.
  • Chemical and oil resistance: Ideal for burner pumps, compressors, and hydraulic systems where lubricant exposure is common.
  • Fail-safe operation: Designed to keep the drive engaged via the hub jaws even in the event of an elastomeric failure.
  • Maintenance-free performance: Requires no lubrication or periodic adjustment once properly aligned during installation.
  • Standardized compatibility: Directly replaces L-Jaw coupling inserts from major manufacturers including Lovejoy, Martin, and Browning.

Common Technical Questions

  • What is the difference between SOX and NBR? In the context of Lovejoy couplings, SOX is the specific trade name for their Nitrile (Buna-N) rubber material, known for its resilience and oil-resistant properties.
  • How do I know when to replace the L110 spider? Visible signs of wear, such as thinning of the legs to 75% of their original thickness or excessive backlash between the jaws, indicate it is time to swap the insert.
  • Can I use this for high-torque start/stop cycles? Yes, NBR is more suited for cyclic loads and high-frequency start/stops compared to urethane or Hytrel alternatives.
  • Will this fit an AL110 hub? Yes, the AL110 (aluminum) and L110 (sintered iron) hubs use the exact same dimensions for the spider cavity.
