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.

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, 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. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways. A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit. Made of spring steel, they flex under stress and shock and can handle oscillating or slow rotational motion.

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 keyless bushing shaft and outer sleeve against the hub, keyless bushing.

Unlike bushings with keyways, a keyless locking bushing is infinitely phase-adjustable, both radially and axially. Automation Machines. We will reply to your message within an hour. To calculate the overhung load, measure the distance from the center of the coupling to the center of gravity of the motor. Posi-Lok PSL keyless shaft bushings are locking devices that provide a secure shaft-to-hub connection. This ring-locking mechanism leaves no room for backlash, meaning that all of the turning force created by the motor is passed on to the second shaft. Click image to enlarge. Quick-Grip Screw-Clamp Bushings. For technical drawings and 3-D models, click on a part number. 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. Overall Wd.

Overhung Load Cap. The ring is under tension, and a sudden release of the collars can cause serious injury. 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. We offer various models and styles to meet your high-performance application requirements. Pedestal 35" Ht. Use a torque arm to prevent hanging motors from spinning. Request a Quote. To remove, gradually loosen each screw in sequence until you can slide the coupling on the shaft. Press Fit. We offer a full selection of shaft-mount models and materials to fit a wide variety of applications. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. Overall Lg. For Motion Type Each Steel.
