JA QD Type Bushings

The benefits of casing go beyond reducing energy transmission. They reduce lubrication costs. If 2 metal parts are in direct contact, lubrication is required. Thus, the bushing minimizes the need for lubrication. They also allow parts of the car to move freely. For example, rubber bushings may deteriorate due to high internal temperatures or cold weather. Also, oil affects its performance. Among other uses, the casing is used in diagnostic equipment.

This JA bushing is a high-quality, extremely durable, and high-precision product made of solid steel. Sleeve assemblies provide a safe, reliable connection between objects with different electrical charges. They also prevent sparking by increasing the electrical conductivity of the component and reducing its resistivity, thereby minimizing the chance of spark formation. An extensive quality control program sets these JA QD-style bushings apart to ensure you get a consistently high-quality product. JA bushings are versatile, most commonly used in sprockets, pulleys, and more! We make it easy to do business with us. Plus, we’re your one-stop-shop for almost any powertrain product!

Standard Mounting

1. Make sure the cone on the bushing and the inside of the driven product is clean and free of oil or any anti-seize lubricant.
2. Slide QD bushing on a shaft, flange end first, then assemble key.
3. Place the QD bushing on the shaft. Use only a standard Allen key to tighten the set screw on the key (hand-tight). Don’t push too hard.
4. Slide the large end of the sprocket or other part taper hole into place over the cone, aligning the drilled bolt holes on the sprocket or other part with the taper holes in the bushing flange. Then assemble the pull-up bolt and lock washer.
5. Tighten the pull-up bolts alternately and evenly to the tightening levels shown in the torque table below. Do not use extensions on wrench handles. There should now be a gap between the face of the sprocket or other part hub and the flange of the QD bushing to ensure a satisfactory tapered grip and press fit. NOTE: This gap must not be closed.

Dismounting

In addition to providing shock and vibration isolation, bushings help stabilize components by absorbing shock. In the long run, these devices may need to be replaced, and your machine design may dictate whether you need to buy more than one. Bushings are an important part of your equipment, so don’t skimp on quality when choosing a vibration isolation mount. You won’t regret it. They won’t break your budget, but will keep your equipment safe.
