Lovejoy 68514410210 Hub
The Lovejoy 68514410210 Hub is a foundational component for industrial power transmission, specifically designed for L050 Jaw Shaft Couplings. Engineered from high-strength sintered iron, this hub provides a durable, cost-effective solution for fractional horsepower applications. This unit features a precision-machined 1/2" bore with no keyway, relying on a robust single set screw for secure shaft attachment. Its fail-safe design ensures that even if the elastomeric spider fails, the intermeshing jaws continue to transmit torque, preventing total system collapse in critical HVACR or pumping environments.
Capable of supporting nominal torque up to 26.3 in-lbs and reaching speeds of 18,000 RPM, this straight jaw coupling hub is optimized for performance in harsh settings. The metallic construction is inherently resistant to oil, dirt, grease, and moisture, making it a reliable choice for HVAC equipment and general industrial machinery. Its ability to accommodate both angular and parallel shaft misalignment through the use of a compatible insert reduces vibration and protects sensitive motor bearings from premature wear.
Key Benefits- Universal Compatibility: Standard L-type design integrates with all Lovejoy L050 series spiders, including Buna-N, Urethane, and Hytrel inserts.
- Superior Durability: High-density sintered iron construction offers dimensional accuracy and resistance to environmental contaminants.
- Keyless Installation: The no keyway configuration with included set screw simplifies mounting on smooth 0.500-inch shafts.
- Fail-Safe Protection: Jaw-to-jaw interlocking ensures drive continuity even during extreme elastomeric member fatigue.
What is the maximum RPM for this hub?
The Lovejoy 68514410210 is rated for a maximum speed of 18,000 RPM, making it suitable for high-speed motor applications.
Does this include the spider insert?
No, this part number is for a single jaw coupling hub. A complete assembly requires two hubs and one elastomeric spider sold separately.
Can I use this on a keyed shaft?
Yes, but since this hub has no keyway, it will only secure via the set screw. For high-torque applications requiring a key, we recommend a keyed L050 hub variant.
