This L-Jaw flexible coupling set ensures smooth, backlash-free power transfer between 1/2 and 3/4 inch shafts with keyways and set screws, featuring HT250 hubs and Buna-N rubber spider for durable, vibration-damping performance

L-Jaw Flexible Coupling 1/2 to 3/4 in with Buna-N Rubber
✔️ 1/2 in and 3/4 in bore, NBR insert, HT250 hubs, zero backlash

This L-jaw coupling set includes two HT250 steel hubs and an NBR rubber spider, designed for 1/2 in and 3/4 in shafts with corresponding keyways and set screws. It is ideal for connecting high-speed drives like pumps, gearboxes, conveyors, mixers, and mowing equipment where smooth torque transfer and vibration damping matter.

✅ 1/2 in bore with 1/8 in keyway and set screw on one half (12.7 mm bore; 3.175 mm keyway)
✅ 3/4 in bore with 3/16 in keyway and set screw on matching half (19.05 mm bore; 4.7625 mm keyway)
✅ NBR rubber spider dampens vibration and shocks
✅ Curved jaw hubs press into rubber insert for zero backlash and reduced deformation
✅ HT250 steel hubs provide strength and rigidity for high RPM use

💡 What is an L-jaw coupling used for in power transmission systems? This handy component helps transfer torque smoothly and damp torsional vibrations in drive lines. - High torque transmission with controlled backlash - Vibration damping reduces noise and extends equipment life - Suitable for misalignment and high RPM in pumps, gearboxes, conveyors
