NOS! Vintage Congress 9.00” OD 1” Fixed Bore Die-Cast V-Belt Pulley,
Type A
This listing is for one (1) vintage 9” Outside Diameter, Type A, 1” fixed-bore die-cast V-belt pulley. This vintage new old stock pulley comes from a now closed 80-year-old neighborhood hardware store in Northeast Philadelphia. The unused industrial v-grooved pulley was manufactured by Congress Drives in Detroit, Michigan, circa 1950’s. This is a Classical Type A Pulley with a ½” wide groove. Most pulleys manufactured today are Type A pulleys. Several of these new old stock pulleys are available, most with the original worn boxes, a few without. Each will be packed and shipped with care.
Please visit our eBay store at The Other Man's Store to view additional new old stock pulleys from Congress, Central Drives, Browning, and more. We have hundreds of pulleys in stock with sizes from 1” to 16”, including variable pitch pulleys, all unused and most in the original boxes.
The following information is provided for reference:
Fixed-bore die-cast
V-belt pulleys have a finished bore,
or center hole, that is machined to a set diameter to insert a shaft of the
same size. They are ready to install with machined keyways and/or set screws to
secure the shaft and prevent slipping. These die-cast pulleys are non-corrosive,
lightweight, impact-resistant, and non-toxic. They are suitable for light duty
applications such as fans and blowers in HVAC applications.
To determine what type of belt is on your pulley, measure the
width of the belt. Most fan belts are A type belts with a measurement of 1/2″.
If the fan belt measures 5/8″ it is classified as type B belt.
The Main Types of V-belts
There are three main types of V-belts that you can use in your
facility, the Classical V-belts, Narrow V series, and light-duty type:
Classical V-Belt
This is one of the most common types of V-belts you can get out there and it has also been around for the longest
period compared to the other two. The first V-belt design replaced the leather
types by taking over most of their applications in industries such as
agriculture, industrial, and industrial machinery.
The classical V-belts can handle loads of a wide range, up to 500
HP. They also come with impressive tolerance levels. However, we must indicate
that they are not as efficient as the narrow V-belt type. Below is a
cross-section presentation of Classical-V-belt designs of different
sizes.
Narrow V Series
If you want to deal with larger loads, it might be a good idea to
do away with the classical V belts and grab several Narrow V series category
belts. They are able to handle more loads because of their greater depth to
width ratio. They are also preferred for drives run by high-speed motors. With a narrow V series belt, it is possible to transmit up to
three times more horsepower than you would do with a Classical V-belt type. See
the cross-sectional dimensions of the narrow V series belts.
Light-Duty V-belt Category
Light-duty belts (also known as fractional horsepower belts) are
mainly single belts used on drives of one or less horsepower. Therefore, they
are designed for relatively light loads, and you will find them an excellent
option for cleaning machines, HVAC systems, refrigerators, and garage equipment. Even when they
appear to fit well, light-duty V-belts should never be used with heavy-duty
industrial applications. Light-duty V-belts are identified with prefixes 5L,
4L, 3L, and 2L. Check out the classification of their cross sections
below:
