3D Series Cast Iron QD Bushing Sheaves Pulley for “D” Belts

3D Series Cast Iron QD Bushing Sheaves Pulley for “D” Belts

3D series three-groove QD bushing sheaves pulley are manufactured for D-series classic v-belts and D-banded belts; they range from 12.64″ to 40.64″ in diameter. Depending on the sheave size, they are made to use F or J QD (quick detachable) bushings, which we also stock. Most of our 3D QD bushing sheave pulleys are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.

Related Matching D-Series, D-Series Banded V-Belts

(1) D-Series V-Belts

Classic D-Series V-Belts have a 1.25″ top-width, 0.75″ thickness, and a 40° angle. Additionally, D V-belts are one of the oldest styles of V-Belts in the industry. Because of their long-term success and economical operation, they are also one of the industry’s most widely used belt series. The premium D-series v-belts we supply are manufactured under ISO 9001 specifications, are oil and heat resistant, and directly interchange with other brands. They are constructed of a natural rubber compound with polyester cords and use cotton with a polyester blend cover for high durability.

(2) D-Series Banded V-Belts

D-series v-belts are a part of the “classic” lineup of v-belts because they are one of the oldest style belts used and one of the most common. Our belts are manufactured by ARPM standards and offer superior strength, durability, and performance. D-series v-belts have a 1-1/4″ top-width per belt (band/ rib).

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.

D-Section V-Belts Pulleys

Stop the headaches of excessive wear and broken-down machinery by upgrading your parts today. We proudly stocks the most popular D-section V belt pulley dimensions. Please browse through our inventory to discover the difference. Every D-belt pulley comes with a phosphate coating and paint sealant. These details contribute to corrosion resistance while the part is on the job. Take a closer look at a D-section v belt pulley, and you’ll also appreciate the machined quality. Each sheave goes through a complex balancing process. Asymmetry and vibrations will never be part of your setup. With these features in mind, you can decide on the final details necessary for your facility.

Select either quick-detachable or taper-lock styles to fit your needs. Regardless of the type, the parts will always hold up to ARPM standards as you put them into motion. You’re welcome to vary your belt selections with these sheaves too. Fit classic V-belts onto the part along with the alternative in banded D-belts. Much of the versatility in our roles is due to the material picked for production. You’ll always have grade 35 cast iron supporting your machines.

Details to Pay Attention to when Replacing the Pulley:

When the production equipment is used for a long time, its parts are inevitably worn out and must be replaced. When replacing the European standard tapered sleeve pulley, remove the locked screw with a suitable Allen wrench. Then, screw the removed screw into the disassembly hole so that the pulley and the tapered sleeve are separated. If the taper sleeve cannot be removed from the shaft, use a rubber tool to tap lightly to disengage the taper sleeve from the shaft. In addition to these, what details should be paid attention to when replacing the pulley?

Details to pay attention to when replacing the pulley:

1. When replacing the pulley, first ensure that the surface of the pulley is not damaged, and apply lubricating oil to the shaft hole so that the pulley can be removed more quickly so as not to affect the subsequent use;

2. When installing the tapered sleeve as a pulley, pay attention to the method of self-locking with screws, and it cannot be installed with other tools such as hammers.

3. Rotate the bolts out of the fastening holes, and then screw the bolts into the dismantling holes simultaneously. At this time, the bolts need to be forced at the same time. The pulley will fall off the tapered sleeve when the dismantling holes are stressed simultaneously. The work of removing the pulley is completed.

4. Put the pulley into the shaft, insert the tapered sleeve into the keyway of the post to adjust the position, send the pulley into the tapered sleeve, and then screw the bolts into the fastening holes. When the pulley is found to be offset, it can use the bolts into the disassembly hole for adjustment. When the adjustment is made, the installation of the pulley is completed. The keyway should be adequately tight in the groove of the shaft. If it is too fast or loose, it will damage the key and the track, and the belt will slip or vibrate if it is too loose. Therefore, contact the technician for verification immediately when selecting a model.
