Lovejoy 68514411514 Hub
The Lovejoy 68514411514 is an industry-standard L100 Jaw Coupling Hub, precision-engineered from sintered iron for reliable power transmission in HVACR and general industrial applications. Designed for a 7/8" finished bore, this hub features a standard 3/16" x 3/32" keyway and a single 5/16-18 set screw to ensure a secure, slip-free connection on keyed shafts. As a critical component of a three-piece coupling assembly, the L-type jaw coupling design excels at accommodating angular and parallel shaft misalignment while maintaining a fail-safe operation—ensuring the drive remains intact even if the elastomeric spider fails. With a maximum rating of 7000 RPM and a nominal torque capacity of 417 in-lbs, this straight jaw hub is ideal for direct-drive motor applications for pumps, compressors, and blowers. Its metallic sintered construction provides excellent resistance against oil, moisture, and dirt, making it a robust choice for demanding contractor environments where longevity and precise shaft alignment are non-negotiable.
Key Benefits- High Torque Density: Efficiently handles up to 417 in-lbs of nominal torque for demanding mechanical loads.
- Misalignment Compensation: Protects bearings and motor shafts by absorbing parallel and angular misalignment through the elastomer interface.
- Fail-Safe Design: The interlocking jaw design ensures continued operation even in the event of an elastomeric member compromise.
- Maintenance-Free: Requires no lubrication or periodic adjustment once the set screw is torqued to spec.
- Environmental Resilience: Sintered iron construction is resistant to common contaminants like oil, grease, and sand.
What components are needed for a complete assembly?
A standard L-type coupling requires two hubs and one elastomeric spider. This part number (68514411514) represents a single hub only.
Is this hub compatible with different spider materials?
Yes, the L100 hub can be paired with NBR (SOX) rubber, Urethane, Hytrel, or Bronze spiders, depending on your torque and temperature requirements.
Does this hub include the key?
No, while the hub is machined with a standard 3/16" x 3/32" keyway, the shaft key must be sourced separately.
