Behind the part quantity a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is certainly a QD or taper bushed design the center letter for the hub designation is certainly changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component number if the sprocket is produced from a particular material. This designation can 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 spaces.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd quantity of teeth can’t be measured directly, caliper diameters are the measurement over the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle accompanied 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 stage directly across the sprocket. It really is comparatively unimportant as the tooth size is not essential to proper meshing to with the chain. The exterior diameter may vary depending on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub in one side to some other. This diameter must not surpass the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper strength. The dimensional allowance must be designed for keyway and set screws.
Face Width (T) – Encounter width is limited in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal width is limited to provide the correct strength to transport the imposed loads.
Length Thru Bore (L) – The length thru bore should be sufficient to allow a long enough important to withstand the torque transmitted by the shaft. This also actions the balance of the sprocket on the shaft.
ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages can 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 cash. Additionally, the functionality of a conveyor or drive depends on sprocket-chain conversation. Using the right sprocket is simply as important as choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to perform well under pressure and so are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet up with both ANSI and ASME specifications.
We’re positive you’ll end up being happy when you buy industrial chain sprockets inside our shop, because they’ll last you quite a long time.

Our knowledgeable staff, excellent items, and unbeatable prices are the known reasons for our A+ BBB ranking!
Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We stock a complete type of each type! Our standard solitary strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are completed with black-oxide for corrosion resistance.
To start shopping simply select what chain size you are employing with your sprocket. Next 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 queries or difficulty finding or selecting your sprocket please contact our customer service department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are designed to operate two single-strand type roller chains, this is where the name “dual single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD design is available from stock. Our double solitary sprockets are produced with hardened tooth and have a black oxide coating for excellent 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 are able to also supply quick reaction custom re-bores and MTO specialty double single sprockets due to our quick reaction in-house machine store. Something important to note is that despite the fact that these sprockets are dual sprockets they will not double-strand roller chain. The charts below show the in-stock double one sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “conditions” or nomenclature to spell it out their sprockets. Though, throughout the general background of roller chain sprockets almost every produce utilizes four different types of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or just “plate sprocket” can be a flat sprocket plate-wheel without hubs that extrude on either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also called C-Hub sprockets is 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 begins with 
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Solitary (these sprockets are created to run two single-strands of roller chain aspect parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” make use of a tapered bushing that’s bolted in to the bore that is machined in the sprocket. When the bushing is certainly inserted into the sprocket is certainly 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 ranking can be exceeded the shear gadget 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 number, standardly the chain pitch will be created first, then the hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket is multi strand there will most often be a letter prefix at the start of the part amount.
