Tapered And QD Bushings

F Series QD Bushings

Martin Sprocket F Series QD bushings are used in power transmission systems for securing and mounting pulleys, sheaves and sprockets onto shafts in power transmission applications. These bushings are employed in industrial machinery and conveyor systems. They feature cast iron construction for ensuring strength and reliability and have torque capacity up to 30000 lb-inch for enabling efficient power transmission without slipping. These bushings can be mounted in two ways: with the flange toward the motor / machine or away from them for providing flexibility in installation. They are equipped with accessible set screws from the outside to allow secure and easy clamping to the shaft.

Tapered And QD Bushings

Tapered & QD bushings are suitable for power transmission drives for driving sprockets, pulleys & chain couplings. Raptor Supplies is an authorised distributor of Lisle, Gates, TB Wood's, Lovejoy, Power Drive and Vulcan Hart tapered & QD bushings. Selected models feature a precise taper for providing wedging action and a Sure-Grip design for accommodating shafts of various diameters. Choose from a wide variety of these tapered & QD bushings, available in sizes (bore diameters) ranging from 15/16 to 9 inches.

Working Mechanism

Tapered Bushings


  • Tapered bushings have a bore which when tightened with a screw or bolt, helps expand and create a tight interference fit between the shaft and the hub.
  • This interference fit provides a secure connection which can handle high torque and axial loads.

QD Bushings


  • QD bushings consist of a bushing and a flange that fit together into a hub or component.
  • The bushing has a tapered bore that fits over the shaft and the flange is bolted onto the hub or component, compressing the bushing and forcing it to expand radially, thus providing a secure and reliable connection.

Features

Martin Sprocket Tapered Bushings :

  • These flush-mounted bushings have a silt taper that reduces mounting width and a tight clamp to shafts.
  • They are made of sintered steel for providing excellent strength and resistance.
  • They feature a bore with a keyway that locks the shaft to prevent it from rotating in the bushing.
  • These tapered bushings are interchangeable and can be mounted to a pulley, sheave or sprocket on a drive shaft.

TB Woods QD Bushings :

  • These Sure-Grip Series QD bushings comprise a set screw over the key to secure the bushing's position on the shaft until the screws are tightened.
  • They have a split-flange and taper design to provide a true clamp on the shaft, with twice the force as compared to standard bushings.
  • These bushings come with drilled and tapped holes which allow a bushing in each end to be mounted on a common shaft with two keyways in line. They thus facilitate installation / removal as well as permit both bushings to carry a uniform load on each end.

Frequently Asked Questions

How can I install a QD bushing?

  • Inspect QD hubs and bushings for any signs of damage. Remove all nicks, paints and grease from mating surfaces.
  • Position the compatible key in the shaft's keyseat.
  • Slide the bushing onto the shaft and key. Make sure that the small end of the taper is outboard.
  • Slide the tapered hub over the bushing.
  • Align the shaft key with one of the slots in the hub.
  • Similarly, align the drilled holes in the mating hub with the threaded holes in the bushing.
  • Put one cap screw into each drilled hole in the mating hub and the threaded hole.
  • By using a torque wrench, tighten all cap screws uniformly and progressively in rotation.
  • Avoid lubricating or using excessive wrench torques, which may lead to hub stresses that might result in the breaking of the mating hub.

What are the factors to consider while selecting a bushing for my application?

Factors to consider while choosing appropriate bushings for your application include size and type of shaft, the amount of torque and horsepower required and the type of equipment being mounted.
