Related Matching 5V, 5VX Series V-Belt

(1) 5V-Series V-Belts

Classic 5V-Series V-Belts have a 0.63" top-width, 0.53" thickness, and a 38° angle. Additionally, 5V 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 5V-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. 5V series belts are used in most general heavy-duty industrial applications along with Heating, ventilation, air conditioning (HVAC), lawn and garden equipment, and agricultural equipment.

(2) 5VX Cogged V-Belts

5VX cogged v-belts are designated by having a 0.53" top-width and 0.53" thickness. Our cogged 5VX v-belts are manufactured with raw-edge sidewalls to eliminate slippage and increase efficacy, saving operation costs. They are also manufactured by ARPM standards and are oil and heat-resistant. 5VX belts are constructed from a high-quality chloroprene compound with high-strength polyester chords and have a top fabric built from a cotton polyester blend. Besides the performance, durability, and energy savings benefits, our cogged v-belts will work with existing stand pulleys/ sheaves. Please contact us for a quote on 5VX cogged v-belts or pulleys, and we will be happy to assist you.

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;

Correct Installation Steps of Pulley and Taper Sleeve:

1. Remove the oil, paint, and contaminants remaining on the shaft, the inner hole of the tapered sleeve, the outer surface of the tapered sleeve, and the surface of the tapered hole of the pulley, and remove the surface burrs. Note: The use of lubricant will cause the pulley to crack, do not use any oil when installing.

2. Put the taper sleeve into the taper hole of the pulley, aligning each hole (each complete hole has only half of the thread).

3. Add a little oil to the thread of the mounting screw, and then screw it into the half-threaded hole of the pulley. Note: Do not lubricate the tapered sleeve, the hub's tapered surface, the sleeve's inner cavity, and the shaft. The use of lubricant will cause the pulley to break.

4. Install the key in the keyway of the shaft, install the tapered sleeve of the pulley on the post, and position it, allowing the pulley to move slightly axially when it is locked. Note: When installing a pulley on a vertical shaft, take precautions to prevent the pulley or taper from falling off during installation.

5. Tighten the mounting screws alternately until the tapered surface of the pulley and the tapered sleeve are entirely fitted. NOTE: Do not use a worn hex wrench as it may cause loose fitting or damage to the mounting screws.

6. Check alignment and pulley runout (swing); correct if necessary.

7. Continue to alternately tighten the mounting screws to the recommended shrinking torque value of the mounting screws, as shown in Table 1, and do not apply additional force after reaching the recommended tightening torque value of the mounting screws.

8. To increase the gripping force of the taper sleeve, tap the end face of the taper sleeve moderately with a hammer through the pad iron or sleeve. Note: Do not hit the taper sleeve directly with a hammer.

9. Tighten the taper sleeve mounting screws again after tapping.

10. Re-check the torque after the first test run, and check it regularly in the future. If it is loose, repeat steps 5-9.

Usage Scenario of V-Belt Pulleys and V-Belts

V-belt pulleys are mainly used for long-distance transmission of power, such as the output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, and some small horsepower motorcycles, the transmission of agricultural machinery power, air compressors, reducers, reducers, generators, gins, etc. It is worth noting that gasoline must be used for the last cleaning before assembling the v belt pulley to ensure that the parts are clean and dry ensure that the mating surfaces are tightly fitted and free of oil and have sufficient friction.
