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.

(3) 5V-Series Banded V-Belts

5V-series v-belts are a part of the "classic" lineup of v-belts because they are one of the oldest and most common style belts. Our belts are manufactured by ARPM standards and offer superior strength, durability, and performance. 5V-series v-belts have a 0.63" top-width per belt (band/ rib).

(4) 5VX Banded Cogged V-Belts

All our v-belts are manufactured by ARPM specifications and offer superior performance and durability. Due to their design, banded 5VX cogged v-belts run smoother, more relaxed, and typically outlast a standard banded C v-belt. They also offer a higher efficiency than ordinary banded v-belts, which means fewer energy costs. We can also stock sheaves/ pulleys for 5VX banded belts.

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.

What Factors Should Be Considered When Choosing a V-belt Pulley?

V-belt pulleys are usually made from cast iron (GG) and steel. If required for specific applications, it is also possible to manufacture these components from aluminum, stainless steel, or plastic material. There is also the option of supplying V-belt pulleys with an additional surface treatment if the ambient conditions require this of the drive. Furthermore, V-belt pulleys can be manufactured to customer specifications. Our turning shop can machine standard pulleys based on drawings or customer wishes.

A V-belt drive can have multiple belts running in parallel. Therefore, v belt pulleys are available not only with different diameters but also with various grooves. On request, the pulleys can be supplied with quality class Q 6.3 dynamic balancing. Pulleys with a diameter of more than 125 mm are statically balanced. Dynamic balancing is recommended where the rotational speed is over 30 m/s or the diameter/width ratio is below 4 in combination with a rotational speed of over 20 m/s.

Several factors determine which V-belt type is best suited to a particular drive. These include the application — i.e., what is being driven, the power to be transferred, the desired speed, the center distance of the pulleys, and any possible impact loads. It is also essential to know what ambient conditions are present and whether there are any space limitations.
