Relevant open tapered bushing
Split tapered bushes are one of the most commonly used bushes because they have high overall strength, are easy to install and unload, and have a high retention force to connect the shaft to the drive unit or idler gear assembly. Open tapered bushes are used for various pulleys, conveyor pulleys, and sprockets. Our split taper bushes are steel or cast material and can be interchanged with any other brand. It is designed as a flanged bushing with a tapered cylinder with a slit on each side. We have G series to W2 series split taper bushings and 0.375 inches to 7.438-inch metric hole diameters. For more information or to get a quote for our high-strength open taper bushing, please contact our customer support team, and we will be happy to help you.
Pulley material and production requirements:
1. The pulley materials used for the fan are gray cast iron HT200, HT250, etc. (but steel, copper, aluminum, etc. can also be used according to customer needs).
2. The pulley shall meet the following requirements: lightweight, uniform mass distribution, elimination of internal stress generated in the manufacturing process, and static balance correction of the V-shaped pulley.
Pulley installation method:
1. Check the pulley groove to ensure that there are no scratches or sharp edges and all dimensions meet the standards;
2. Clean the surfaces of all parts, such as hub holes, tapered sleeves, bolt holes, etc. Install the tapered sleeve into the pulley and align all screw holes.
3. Coat the screw (TB1008-TB3030) and thread (TB3525-TB5050) with engine oil and screw them into the mounting hole, but do not tighten them.
4. Clean the surface of the drive shaft, push the belt pulley with a tapered sleeve to the predetermined position on the column, and check whether the V-shaped belt pulley is aligned.
5. When using the keyway, it must be inserted into the hub first, and there must be a certain tolerance between the keyway and the hole hub.
6. Use a hex wrench conforming to the DIN911 standard to tighten the bolts in each mounting hole alternately, gradually, and evenly until the torque shown in the table below is reached.
7. After a short period of operation (0.5 to 1 hour), check the tightening torque of the bolts and retighten them if necessary.
8. To prevent foreign matters from invading, fill the connecting hole of hole with grease.
Audited Supplier 
The specifications of V-belts are divided by the dimensions of back width (top width) and height (thickness). According to different dimensions of back width (top width) and height (thickness), V-belts of different standards have different models. The pitch width, top width and height of V-belts of each model are different, so the pulley must also make various groove types according to the shape of V-belts; These different groove types determine various types of pulley.
