Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed style the center letter for the hub designation is usually changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in 
Bottom Diameter (BD) – This is the measurement of the diameter of a circle tangent to the bottoms of the tooth spaces.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd number of teeth can’t be measured directly, caliper diameters are the measurement over the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle accompanied by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The exterior diameter may be the measurement from the end of the sprocket tooth across to the corresponding point directly across the sprocket. It really is comparatively unimportant as the tooth duration is not vital to appropriate meshing to with the chain. The exterior diameter may vary based on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub from one side to another. This diameter must not exceed 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 must be made for keyway and set screws.
Face Width (T) – Encounter width is limited in its optimum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimum width is bound to provide the proper strength to carry the imposed loads.
Size Thru Bore (L) – The distance thru bore must be sufficient to allow a long enough key to withstand the torque transmitted by the shaft. This also measures 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 machines can’t operate without their drive teach sprockets, and changing them can cost lots of time and money. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is just as important as deciding on the best chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and so are resilient. The roller chain sprockets for sale in our store include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet up with both ANSI and ASME criteria.
We’re positive you’ll be happy when you get industrial chain sprockets in our shop, because they’ll last you a long time.

Our knowledgeable staff, excellent items, and unbeatable prices will be the known reasons for our A+ BBB rating!
SINGLE STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We share a complete type of each type! Our standard solitary strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used high quality quality SAE 1045 metal material, and are completed with black-oxide for corrosion resistance.
To start out shopping simply choose what chain size you are employing with your sprocket. Following choose the type needed, finally select the preferred tooth count and possible accessories needed, you then are ready to obtain your sprockets! If at any point you have questions or difficulty finding or picking your sprocket please contact our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are made to operate two single-strand type roller chains, that’s where the name “dual single” originated from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from share. Our double single sprockets are manufactured with hardened teeth and have a black oxide coating for superior performance and hook corrosion resistance. Stock sizes of double single sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We can also supply quick reaction custom re-bores and MTO specialized double single sprockets because of our quick reaction in-house machine shop. Something important to note is that despite the fact that these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below display the in-stock double one sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to spell it out their sprockets. Though, through the entire general background of roller chain sprockets nearly every produce utilizes four different types of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or simply “plate sprocket” can be a set sprocket plate-wheel with no hubs that extrude upon either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also called C-Hub sprockets can be a sprocket with a hub that extrudes on both sides.
Design D, is a sprocket with a detachable bolt-on hub mounted on a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets will start 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 many other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are made to operate two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” use a tapered bushing that is bolted into the bore that is machined in the sprocket. When the bushing is usually inserted into the sprocket can be compresses onto the shaft, which provides a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another style 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 rating is definitely exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part number, standardly the chain pitch will be written first, then the hub style or code, and accompanied by the number of the teeth the sprocket has. If the sprocket is multi strand there will frequently be considered a letter prefix at the start of the part number.
