Lovejoy 68514411089 Hub
The Lovejoy 68514411089 Hub is a precision-engineered L095 Jaw Shaft Coupling component, manufactured from high-strength sintered iron for reliable power transmission in industrial HVACR and hydraulic applications. This L-type hub features a 7/8" finished bore equipped with a standard 3/16" x 3/32" keyway and a single 5/16-18 set screw to ensure a secure, slip-free interface on the drive or driven shaft. Designed for versatility, the three-jaw configuration provides a fail-safe connection that maintains torque transfer even if the elastomeric spider fails. With a maximum speed rating of 9,000 RPM and a nominal torque capacity of 194 in-lbs (using a NBR spider), this hub is capable of handling peak loads up to 5.5 HP at 1,800 RPM. The 2.11" outside diameter and 1.00" length through bore offer a compact footprint for tight pump-to-motor alignments. This hub is fully interchangeable with industry-standard L095 components from major manufacturers.
Key Benefits- Corrosion Resistance: Sintered iron construction provides a durable, metallic finish resistant to oil, moisture, and common industrial contaminants.
- Fail-Safe Operation: The jaw-and-spider design prevents total power loss; even if the insert degrades, the jaws will lock to maintain shaft rotation.
- Misalignment Compensation: When paired with an appropriate spider, this hub accommodates angular and parallel misalignment, reducing stress on motor bearings.
- Torsionally Soft: Ideal for protecting sensitive HVACR equipment by dampening vibration and shock loads across the drivetrain.
- Zero Maintenance: Once properly installed and aligned, the coupling requires no lubrication and minimal visual inspection.
What components are needed for a full assembly?
A complete L095 coupling requires two hubs and one elastomeric spider. This SKU includes one hub only; ensure you select the correct bore size for your second hub to match your specific shaft requirements.
Is the keyway included on this model?
Yes, this hub comes with a factory-machined 3/16" x 3/32" keyway and a 5/16-18 set screw. It is ready for immediate installation on any standard 7/8" shaft without additional machining.
Can this hub be used with secondary spiders like Hytrel or Urethane?
While performance ratings typically assume a Buna-N (NBR) spider, the L095 hub is compatible with Urethane and Hytrel inserts for applications requiring higher torque or specialized chemical resistance.
