Keyless bushing

Also known as Trantorque bushings, these tighten with a twist of the collar nut— no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, keyless bushing gear.

Most models feature socket-head cap screws for easy tightening and distribution of pressure over the full length of the connection to reduce fretting, corrosion, and backlash. Posi-Lok bushings are ideal for positioning and locking shaft components in a system, and eliminate the need for keyways, tapers, and tapped holes, which can weaken or cause excess wear to shaft couplings.

Keyless bushing

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. Reduce Stress and Wear on Mounted Components with Keyless Bushings Keyless bushings make mounting components an easier, faster, and more precise process. All you need to do is mount, set in position, and lock it with a torque wrench. Unlike bushings with keyways, a keyless locking bushing is infinitely phase-adjustable, both radially and axially. This feature makes them more precise and easier to use. They can be tightened and repositioned with minimal downtime and without causing additional wear on the shaft or mounted components. And, because they eliminate the need for milled keyways in shafts, smaller shafts can be used to transmit the same amount of torque, thereby saving space and material.

ETP keyless bushings are shaft locking devices used to create precise shaft-to-hub connections in high-demanding applications. They are ideal for positioning and locking shaft components in a system, and provide the best alternative to keyways and tapers, which can weaken or cause excess wear to shaft couplings. Keyless shaft bushings enable fast, precision mounting of shaft components, providing solutions in the following situations:. For more information on our ultra-low runout, ETP keyless shaft bushings, contact us or find your local sales representative. Zero-Max ETP keyless locking devices are designed to solve specific application requirements, such as phasing and timing to synchronize machine components. ETP keyless bushings feature double-walled sleeves and tightening mechanisms that form solid, continuous connections between shafts and hubs when tightened. All ETP keyless shaft bushings slide easily onto shafts to quickly and securely lock motion control components into position. Disassembly of the shaft-to-hub connection is equally fast. See specific model information below for complete details. View Quote.

The PSL-D series bushings have a single taper, offering a lower contact pressure at the hub, allowing smaller OD hubs to be used, saving on the moment of inertia and weight. 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. Most models feature socket-head cap screws for easy tightening and distribution of pressure over the full length of the connection to reduce fretting, corrosion, and backlash. Posi-Lok Bushings Provide High Torque Transmission and Reliable Performance Posi-Lok keyless shaft bushings utilize tapers that form a mechanical locking wedge as the actuation screws are tightened, pressing the inner sleeve against the shaft and outer sleeve against the hub.

They can be mounted on shafts with or without keyways. Surface pressure is distributed evenly over the full length of the connection, reducing micro-movements which can cause fretting. The clamping screws on the coupling face squeeze two outer collars against an inner ring, pressing it tight against shafts to lock them together. Send Cancel.
