Lovejoy 68514411070 Rubber Insert

The Lovejoy 68514411070, also identified as the L-090/095SOX, is a high-grade NBR (Nitrile Butadiene Rubber) elastomeric spider designed for jaw-type shaft couplings. This SOX rubber insert features a solid center, providing essential dampening for misalignment and vibration in industrial drive systems. Engineered for high-stress HVACR and mechanical power transmission applications, this jaw shaft coupling insert offers excellent oil and chemical resistance, making it ideal for petroleum-based lubricants and hydraulic fluids. The L090/L095 spider maintains operational integrity across a broad temperature range, ensuring stable torque transmission between the coupling hubs. Technicians typically utilize this 70 Shore A durometer insert to reduce hardware wear by absorbing shock loads and compensating for angular, parallel, and axial shaft deviations. Its nitrile rubber construction prevents metal-to-metal contact, significantly extending the service life of connected motors and pumps.

• Oil-Resistant NBR Construction: High-quality nitrile rubber ensures durability in environments exposed to grease, oil, and chemicals.
• Vibration Dampening: The elastomeric spider absorbs shock loads to protect delicate drivetrain components.
• Solid Center Design: Increases structural rigidity and facilitates easier alignment during installation compared to open-center variations.
• High Torque Capacity: Designed to fit L090 and L095 coupling hubs for reliable power transmission in heavy-duty cycles.

Common Technical Questions

What is the temperature range for the L-090/095SOX insert?
The NBR (SOX) insert is rated for continuous operation from -40°F to 212°F (-40°C to 100°C), covering most standard industrial and HVACR motor applications.

How do I know if I need a solid center or open center spider?
Solid center inserts like the 68514411070 are used when shafts are spaced far enough apart that they do not interfere with the center of the spider. They provide better support for the spider lugs during high-RPM operation.

Can this NBR spider be used in high-heat chemical environments?
While nitrile rubber excels in oil resistance, for high-heat or extreme chemical exposure, you may need to evaluate Urethane or Hytrel alternatives depending on the specific torque and environmental requirements.
