Behind the part amount a suffix of “H” is added if one’s 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 certainly changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the part amount if the sprocket is manufactured 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 – Since the bottom level diameter (BD) of a sprocket with odd number of teeth cannot be measured directly, caliper diameters are 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)
Outside Diameter (OD) The exterior diameter is the measurement from the end of the sprocket tooth across to the corresponding point directly over 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 based on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub from one side to some other. This diameter must not go beyond the calculated diameter of the inside of the chain sidebars.
Optimum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper power. The dimensional allowance must be designed for keyway and arranged screws.
Face Width (T) – Face width is bound in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the proper strength to transport the imposed loads.
Duration Thru Bore (L) – The space thru bore must be sufficient to allow an extended 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 may bring your machinery to a grinding halt. Many devices can’t operate without their drive teach sprockets, and changing them can cost a lot of time and cash. Additionally, the functionality of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is just as important as selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of standard 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, 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 be happy when you get industrial chain sprockets inside our store, because they’ll last you quite a long time.

One STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete line of each type! Our standard single 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 shopping simply choose what chain size you are using with your sprocket. Next choose the type needed, finally select the desired tooth count and feasible accessories needed, you then are ready to get your sprockets! If at any stage you have queries or trouble finding or choosing your sprocket please contact our customer support department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are designed to run two single-strand type roller chains, this is where the name “double single” originated from. Typically these sprockets are A design but both BTB taper bushed and QD design is available from stock. Our double one sprockets are manufactured with hardened teeth and have a dark oxide coating for superior performance and hook corrosion resistance. Stock sizes of double single sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon request. We are able to also supply quick response custom re-bores and MTO specialized double single sprockets due to our quick reaction in-house machine shop. Something important to note is that even though these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below show the in-stock double one sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “terms” or nomenclature to spell it out their sprockets. Though, throughout the general background of roller chain sprockets almost every produce utilizes four various kinds of sprockets and has adopted the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or just “plate sprocket” is usually a flat sprocket plate-wheel without hubs that extrude upon either side.
Style B, also known as B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also known as 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 a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles and also many other styles upon request.
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 made to operate two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “quick detachable” make use of a tapered bushing that’s bolted into the bore that is machined in the sprocket. When the bushing can be inserted in to the sprocket can be compresses onto the shaft, which gives 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 grasp on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to supply an overload device. If the torque rating is certainly 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 quantity, standardly the chain pitch will be written first, then the hub design or code, and accompanied by the number of tooth the sprocket has. If the sprocket is usually multi strand there will frequently be considered a letter prefix at the start of the part quantity.
