Behind the part amount 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 guts letter for the hub designation is usually changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the component amount if the sprocket is produced from a special material. This designation could be placed in the front of the part number or behind, if it’s 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 number of teeth cannot be measured directly, caliper diameters will be the measurement over the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle accompanied by the centers of the chain pins because 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 stage directly over the sprocket. It is comparatively unimportant as the tooth duration is not essential to correct meshing to with the chain. The outside diameter may vary depending on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub from one side to another. This diameter should never exceed 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 power. The dimensional allowance must be made for keyway and established screws.
Face Width (T) – Face width is limited in its optimum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimum width is limited to provide the proper strength to carry the imposed loads.
Duration Thru Bore (L) – The distance thru bore must be sufficient to allow an extended enough essential to withstand the torque transmitted by the shaft. This also procedures the stability 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 train sprockets, and changing them can cost considerable time and cash. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain interaction. Using the proper sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform 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 both ANSI and ASME specifications.

Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We share a complete type of each type! Our standard single strand roller chain sprockets are produced with hardened the teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are completed with black-oxide for corrosion level of resistance.
To start out shopping simply select what chain size you are using with your sprocket. Next select the type needed, lastly select the desired tooth count and possible accessories needed, then you are ready to obtain your sprockets! If at any point you have questions or problems finding or picking your sprocket please contact our customer service department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are created to run two single-strand type roller chains, this is where the name “dual single” came from. Typically these sprockets are A style but both BTB taper bushed and QD design 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 between ANSI #40 – #160 but additional sizes can be manufactured upon ask for. We are able to also supply quick reaction custom re-bores and MTO specialty double single sprockets because of our quick response in-house machine shop. Something vital that you 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 solitary sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of 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 known as A-Plate or simply “plate sprocket” can be a set sprocket plate-wheel without hubs that extrude upon either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also known as C-Hub sprockets is usually a sprocket with a hub that extrudes on both sides.
Design D, is a sprocket with a detachable bolt-on hub attached to a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets will start with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles along with several other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to run two single-strands of roller chain aspect 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 in to the bore that is machined in the sprocket. When the bushing is inserted in to the sprocket is compresses onto the shaft, which provides 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 use a shear pin type hub that is bolted to a sprocket to supply an overload gadget. If the torque ranking is definitely exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain 
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component number, standardly the chain pitch will be written first, then the hub style or code, and followed by the number of the teeth the sprocket has. If the sprocket is multi strand there will most often be a letter prefix at the start of the part quantity.
