Side Bow Chains 40SB 43SB 50SB 60SB 63SB 80SB
A side bow chain is a type of roller chain with an unusual shape that allows for accentuated lateral bending. These chains are commonly used in power transmission systems and in conveyors with curvilinear motions. They are made with special pins and bushings to minimize the possibility of misalignment. Side bow chains are similar to roller chains except they don’t have a joint between the pin and bush. This feature allows for partial articulation of the chain in the horizontal plane.
Because of the extra clearance between bushings, side bow chains are designed for flexible operation on curvy trails. They come in 2 basic versions, 1 with a conical pin and another with a loose fit bush and pin. The former is a less expensive option but has lower durability and less precise pitching. The latter offers increased durability and a longer lifespan. Other models can be custom-made according to customer requirements. To find out more about side bow chains, check out the following information.
Roller chains with a side bow are generally made from solid roller links, which have extra clearance between pins and bushings. The links of a side bow chain are generally narrower than those of a standard roller chain, so that they can fit through curved surfaces with ease. In addition, these chains can accommodate standard sprockets, which makes them a versatile solution for curved applications. They can be manufactured in stainless steel or different coatings to accommodate various needs.

Side Bow Chains Advantages
There are several advantages of Side bow chains. One of them is that they have a smaller centering projection. This is achieved by the inner link plate having a groove positioned in the middle of it. This groove allows the centering projection to pivot further into the transition region. In this way, the chain can bow sideways and be more stable. In addition, they are much cheaper than conventional designs. Here are some examples of their benefits.
Depending on the size of the sprocket, side bow chains can have a radius of R of less than half the width of the receiving sleeve. They are particularly applicable to screw lifting conveyors, turning machines, and conveyors of food and beverage products. They can also be used in conveyor technology and cleaning technology. And if you have a high-temperature plant environment, you should consider side bow chains.
Another advantage of Side bow chains is their flexibility. They can be adjusted to flex either to the left or the right. Choosing between a conical pin and a loose bush and pin depends on your preferences. The former is cheaper, but has a lower pitching accuracy. The latter has a longer life and is ideal for high-speed operations. Some chains can be customized to fit specific needs, so they can meet specific specifications.
Side bow chains have many advantages. They are widely used for drag and conveyor chains. These chains can negotiate bends thanks to their smaller diameter. Biconical bushes and conical pins are also available. High-pretensioned Ever power transmission roller chains provide a high level of corrosion protection. They are also highly wear resistant and have better fatigue strength than standard chain designs. And thanks to advanced technology and innovative design, these chains can withstand high loads without the risk of detaching.
Sprockets For Chains
There are many different types of sprockets for chains. Some are made of stainless steel, while others are made of non-stainless steel. Stainless steel sprockets are ideal for harsh environments and are usually 304-grade stainless steel. You can also find 316-grade stainless steel sprockets, which are ideal for extreme corrosive conditions. In addition to standard sizes, you can also find idler sprockets with a ball bearing pressed in.
There are 2 standards for sprockets: ISO and metric. ISO sprockets are used in most American, European, and Asian machines. In the United States, ISO sprockets are used to meet stringent standards, while metric sprockets are more flexible and interchangeable with European-style chains. For the most part, sprockets are interchangeable, although there is still a small number of exceptions to this rule.
The most common type of sprockets are made from metal or reinforced plastic. These devices are closely related to gears, and their wheel-shaped design with teeth allows them to span greater distances than their mating gears. Most sprocket and chain systems are similar to bicycle chain assemblies.
To choose sprockets for chains, it’s essential to get the size and pitch of the chain. Depending on your requirements, you may want to select 1 that has wide teeth or a sprocket with small teeth. In addition to pitch, you should also consider the size of the drive shaft. For example, if the chain is large, you will need a sprocket that is wide. For smaller chains, you’ll need a sprocket with smaller teeth. Likewise, you should consider the sprocket bore.
