Overview
The Lovejoy CJ 24/32B jaw coupling hub is a precision-engineered component for flexible power transmission in industrial motion control applications. Made of steel sintered with powdered metals for strength, durability, and corrosion resistance, this curved jaw hub design transmits torque while accommodating shaft misalignment. This hub transfers shock and misalignment from the shaft to the center element of the coupling assembly for reduced wear on the shaft assembly. The 24/32 size rating indicates compatibility with standard Lovejoy CJ Series coupling assemblies.
Key Features
- Curved Jaw Design: No metal to metal contact, still performs if elastomer fails, and resists oil, dirt, sand, moisture, and grease
- No Lubrication Required: Elastomer spider requires no lubrication for extended service life
- Angular Misalignment Capability: 1.5° angular misalignment capability accommodates typical shaft runout
- Elastomeric Element: Central spider dampens vibration and shock loads
- Easy Installation: Set screw fastening for straightforward mounting to shaft
