Behind the part quantity a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket can be a QD or taper bushed design the center letter for the hub designation is usually changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the part quantity if the sprocket is produced from a particular material. This designation could be placed in leading of the part quantity or behind, if it is noted.
Bottom Diameter (BD) – This is actually the measurement of the diameter of a circle tangent to the bottoms of the tooth areas.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd amount of teeth can’t be measured directly, caliper diameters will be the measurement across the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle followed by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The outside diameter is the measurement from the end of the sprocket tooth across to the corresponding point directly over the sprocket. It is comparatively unimportant as the tooth size is not essential to correct meshing to with the chain. The exterior diameter may vary based on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to another. This diameter must not surpass the calculated diameter of the inside of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper strength. The dimensional allowance should be made for keyway and set screws.
Face Width (T) – Face width is bound in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimum width is bound to provide the correct strength to transport the imposed loads.
Duration Thru Bore (L) – The length thru bore should be sufficient to allow an extended enough crucial to withstand the torque transmitted by the shaft. This also steps the balance of the sprocket on the shaft.

ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages may bring your machinery to a grinding halt. Many devices can’t operate without their drive teach sprockets, and changing them can cost considerable time and money. Additionally, the efficiency of a conveyor or drive depends on sprocket-chain interaction. Using the proper sprocket is simply as important as choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and so are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets fulfill both ANSI and ASME requirements.
We’re positive you’ll end up being happy when you get industrial chain sprockets inside our shop, because they’ll last you quite a long time. If you’re not sure what sprockets will be the ones you will need for your machine, make sure you don’t hesitate to give us a call. Our knowledgeable staff, excellent products, and unbeatable prices are the reasons for our A+ BBB rating!
Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete type of each type! Our standard solitary strand roller chain sprockets are produced with hardened the teeth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are finished with black-oxide for corrosion resistance.
To start out shopping simply choose what chain size you are using with your sprocket. Next select the type needed, lastly select the desired tooth count and possible accessories needed, you then are ready to obtain your sprockets! If at any point you have queries or difficulty finding or choosing your sprocket please contact our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are created to operate two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets certainly are a style but both BTB taper bushed and QD style is available from stock. Our double solitary sprockets are manufactured with hardened teeth and have a dark oxide coating for excellent performance and a slight corrosion resistance. Share sizes of double one sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets because of our quick reaction in-house machine shop. Something vital that you note is that even though these sprockets are dual sprockets they will not double-strand roller chain. The charts below display the in-stock dual solitary sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to spell it out their sprockets. Though, through the entire general history of roller chain sprockets almost every produce utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or just “plate sprocket” is certainly a set sprocket plate-wheel with no hubs that extrude on either side.
Style B, also known as B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also called C-Hub sprockets is a sprocket with a hub that extrudes on both sides.
Style D, is a sprocket with a detachable bolt-on hub attached to a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets begins with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles and also various other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are created to operate two single-strands of roller chain part parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” utilize a tapered bushing that’s bolted in to the bore that is machined in the sprocket. When the bushing is usually inserted into the sprocket is compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that provides a positive hold on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to provide an overload device. If the torque ranking is usually exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component amount, standardly the chain pitch will be created first, then your hub design or code, and accompanied by the number of teeth the sprocket has. If the sprocket is definitely multi strand there will most often be considered a letter prefix at the start of the part number.
