Heavy Duty Flexible Shafts

Our flexible shafts are designed to handle the demands of high-torque applications. They feature a strong steel core, protective plastic case, and bearings to ensure reliable performance. These shafts can transmit rotary motion along any path, snaking around curves and obstructions. You can manually rotate them with a knob (not included) or mechanically.
Our shafts come with either ball bearings or sleeve bearings, depending on your needs. Those with ball bearings allow for higher speeds. To secure female fittings, tighten the set screw. For male fittings, simply push the male end of the shaft through a panel cutout and secure with locknuts. The fittings have a D-profile for fastening to a manual control knob. Order your high-torque flexible shafts today and take your rotary motion to the next level!
