Related QD Bushings | Quick Disconnect Bushings

QD bushings are utilized throughout the industrial power transmission and agricultural industry for various sprockets, sheaves, pulleys, and synchronized drives. They are designed for easy installation and easy uninstallation; they are also commonly referred to as quick-disconnect bushings. QD bushings can help conventional mounting with the flange outboard and reverse mounting to where the flange is inboard and utilize a single split that extends through the entire bushing length. Our QD bushings interchange with other brands and are made from high-grade steel precision machined for perfect application fitment. QD bushings' benefits over different styles include; ease of installation/ uninstall, superior holding power, and extreme strengths. We stock all the standard sizes of QD bushings and supply custom QD bushings upon request, including stainless steel ones. QD bushings are found in some of the most rugged applications worldwide; contact our customer service team today for a quote or additional information on our premium QD bushings.

Daily Inspection of the Pulley to See These 3 Aspects Will Do

The pulley is a worn part that often shakes and slips during long-term operation. If the pulley is not checked regularly, it will also cause damage to the machine for a long time and may be directly damaged in severe cases. Therefore, in daily use, we should regularly check the pulley. What aspects of the pulley should be reviewed?

Check these three aspects of the v belt pulley daily:

1. Pulley surface: All standard pulleys are weighted according to the standard. If there are bump marks on the surface of the pulley, it is necessary to observe whether the pulley shakes during operation. If there is vibration, replacing the pulley in time is essential.

2. Pulley belt: The pulley is driven by a belt, so we also need to check the belt regularly. After installation, we should first observe the tightness of the belt. If the building is too tight, it will affect the speed of the pulley. In severe cases, the motor shaft may be worn. If the installation is too loose, it may reduce the machine's working efficiency and cause slippage. If the belt has low aging tension, we need to replace the belt in time.

3. Pulley mounting hole: The mounting hole of the pulley is in direct contact with the motor shaft and is also an essential part of determining whether the machine can run. We need to regularly observe whether the installation holes are clean and whether there are impurities in them. Because contaminants are likely to damage the mounting holes, if mounting holes are damaged, the pulley will not be able to use.

What Are the Pulleys Used For?

The pulley belongs to the hub-type parts. Generally, the relative size is relatively large. The manufacturing process is usually based on casting and forging. Use less cast steel (steel has poor casting performance); generally, smaller sizes can be designed for development, and the material is steel). The pulley is not only used on the car; it is mainly used to transmit power over long distances. It has many applications, such as the power output of small diesel engines, such as tractors, cars, etc. It is also used in mechanical transmissions, such as machining equipment, textile machinery, lathes, and forging machines.
