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, or gear. Stainless steel bushings are corrosion resistant for use in harsh environments. For technical drawings and 3-D models, click on a part number. Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads and have higher torque ratings than self-centering bushings.

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.

All Posi-Lok bushings slide easily onto shafts and securely lock hubs, pulleys, and other mounted components into position along the shaft. Insert these bushings into the bore of your sprocket for flush or recessed keyless bushing. They can be tightened and repositioned with minimal downtime and without causing additional wear on the shaft or mounted components, keyless bushing.

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.

To remove, gradually loosen each screw in sequence until you can slide the coupling on the shaft. The PSL-K series bushings offer small ID and OD dimensions to allow a smaller diameter hub to be mounted, saving on the moment of inertia, cost, and weight. The clamping screws on the coupling face squeeze two outer collars against an inner ring, pressing it tight against shafts to lock them together. For more information on our Posi-Lok keyless shaft bushings, contact us or find your local sales representative. 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. Request a Quote.
