Type of Roller Chain Sprockets
Industrial chain sprocket breakages can bring your machinery to a grinding halt. Many machines can’t operate without their drive train sprockets, and replacing them can cost a lot of time and money. Additionally, the performance of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is just as important as choosing the right chain. At HZPT, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and are long-lasting. The roller chain sprockets for sale in our store include single-strand roller chain sprockets, double-strand roller chain sprockets, and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet both ANSI and ASME standards.

A-Plate Roller Chain Sprockets
A-plate roller chain sprockets are manufactured with no hub and are supplied with just a singular hole in the center. Depending on the sprocket size, this hole can vary in diameter. We can supply these sprockets with the standard stock hole or with a custom bore from our in-house machine shop.
B-Hub Roller Chain Sprockets
B-hub roller chain sprockets are manufactured with a hub on one side. These sprockets are supplied with a stock bore or with a pre-bored finished bore that includes a key-way or 2-set screws. We stock a wide range of bore sizes for standard shaft diameters but if a non-standard or specialty bore is required, we can supply that as well.
C-Hub Roller Chain Sprockets
C-hub roller chain sprockets are designed with a hub on both sides. This style standard comes with a plain hole stock bore, but if a custom diameter bore is required, we can supply that as well.
Taper-Bushed Roller Chain Sprockets
Taper-bushed roller chain sprockets are manufactured with a large inside diameter hole to accommodate the required taper-lock bushing. These sprockets are commonly used because they are easy to change out, and the range of stock bore sizes with taper lock bushings is far greater than that of the sprocket itself. We stock a complete line of taper bushed sprockets and taper lock bushings for immediate delivery. If you need help pairing a specific taper-bushed roller chain sprocket with the right bushing, please give us a call and we will match them for you.

QD-Bushed Roller Chain Sprockets
QD bushed roller chain sprockets (also commonly known as quick detachable sprockets) are designed to quickly detach from the shaft. Typically the sprocket will wear out quicker than the bushing, so replacing only the QD bushed sprocket plate is typically cheaper than having to replace a complete sprocket assembly. Additionally, the range of stock bore sizes with QD bushing is far greater than that of the sprocket it's self. We stock a complete line of QD bushed sprockets and QD-Bushings for immediate delivery. If you need help pairing a specific QD bushing sprocket with the right bushing please give us a call and we will match them for you.

Weld On Hub Roller Chain Sprockets
Weld-on roller chain sprockets are a 2-piece construction sprocket consisting of a plate and a separate hub to weld onto the plate. These sprockets are common in applications that require specialty reduced-hub sprockets such as packaging facilities, and agricultural applications. They are also common because there is a wide range of weld-on hubs such as round bore, hex bore, square bore, and splined bore. Many people keep these types of sprockets on-hand because thy are economical and quick to assemble.
Applications for Roller Chain Sprockets
Chain and sprocket drives are used in many types of industrial applications, such as:
- Rigging and moving heavy materials
- Hydraulic lift truck fork operation
- Increasing or decreasing a driver’s output speed by altering gear ratios between the driver and the sprocket being driven
- Overhead hoists
- Operating conveyer belts
- Conveying materials
Chain and sprocket drives are used in many types of industries to move, slide, carry, push and pull a variety of materials. These drives can be used to move objects directly by attaching pockets, buckets, frames, or meshes to the chains. They can also be used indirectly, such as turning rollers, which in turn, move a conveyor belt.
