12.7mm to 8mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

This aluminum jaw-type flexible coupling adapts shaft sizes from 12.7 mm (0.50 in) to 8 mm (0.315 in) and measures 66 mm long with a 40 mm outer diameter. Used to connect motors to drives in compact machines, robotics, 3D printers, and automation setups, it provides a tight, backlash-minimized link with electrical insulation.

✅ Bore compatibility: 12.7mm to 8mm jaw-type design for easy shaft fit
✅ Length: 66mm overall
✅ Outer diameter: 40mm
✅ Material: Aluminum alloy with electrical insulation
✅ Backlash: zero backlash at low torque for precise motion
✅ Misalignment tolerance: handles angular and parallel misalignment

💡 What is a jaw-type flexible coupling used for in motor and drive systems? This handy choice helps transfer torque while accommodating shaft misalignment. - handy torque transfer with low backlash for light-load drives - absorbs angular and parallel misalignment to reduce stress - ideal for CNC machines, robotics, and small automation tasks - designed for aluminum jaw-type couplers with 12.7mm to 8mm bores
