Keyless shaft bushings provide secure connections between the shaft and hub while reducing stress or wear to mounted components. Using surface pressure to maintain their position, they eliminate the need for keyways, tapers, and tapped holes, which can cause component stress and wear due to fretting, corrosion, and backlash.
A keyless bushing does not rely on the key to transmit torque, but instead utilizes the entire circumference of the shaft for more efficient performance with no backlash. Surface pressure is distributed evenly over the full length of the connection, reducing micro-movements which can cause fretting.
