Rigid Shaft Coupling With 1 In Bore, 2 In OD, 3 In Length, Black Oxide Plated Mild Steel, 5/16-18 x 1/2 In Set Screws, Four Screws For Higher Load Capacity, Easy Install, Delivers Torque Transmission And Shaft Alignment

Rigid shaft coupling: 1 in bore, 2 in OD, 3 in length
✔️ 1 in bore, 2 in OD, 3 in length; 4 set screws for higher load

The rigid shaft coupling connects two shafts to transmit torque while keeping alignment. It's a handy choice for motors, gearboxes, and small machinery where quick, straightforward installation matters.

✅ 1 in bore for standard shafts
✅ 2 in outer diameter keeps a compact profile
✅ 3 in overall length provides solid engagement
✅ Black oxide finish on mild steel adds corrosion resistance
✅ 4 set screws, 5/16-18 x 1/2 in for high load capacity
✅ Easy installation without major disassembly

💡 What is a rigid shaft coupling used for in drive systems and how does it help with torque transmission and alignment? A rigid shaft coupling keeps the shafts aligned and transfers torque with minimal play. - Torque transmission between shafts for reliable power transfer - Maintains axial and angular alignment to reduce wear - Simple installation that minimizes downtime in maintenance - Works with standard bore sizes like 1 in and 2 in OD
