Behind the part number a suffix of “H” is added if the 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 definitely changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the part number if the sprocket is manufactured from a special material. This designation can be placed in the front of the part number 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 – Since the bottom diameter (BD) of a sprocket with odd number of teeth cannot 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 may be 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 is the measurement from the tip of the sprocket tooth across to the corresponding point directly over the sprocket. It is comparatively unimportant as the tooth length is not vital 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 in one side to another. This diameter should never exceed the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper power. The dimensional allowance should be designed for keyway and established screws.
Face Width (T) – Encounter width is limited in its maximum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the proper strength to carry the imposed loads.
Duration Thru Bore (L) – The distance thru bore should be sufficient to allow an extended enough key to withstand the torque transmitted by the shaft. This also steps the stability 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 lots of time and money. Additionally, the performance of a conveyor or drive depends on sprocket-chain conversation. 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 are long lasting. The roller chain sprockets accessible in our shop 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 specifications.
We’re positive you’ll become happy when you get industrial chain sprockets inside our shop, because they’ll last you quite a long time.

Our knowledgeable staff, superior items, and unbeatable prices are the reasons for our A+ BBB ranking!
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 regular single strand roller chain sprockets are produced with hardened teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are finished with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are using with your sprocket. Next choose the type needed, lastly select the preferred tooth count and possible accessories needed, you then are ready to get your sprockets! If at any point you have questions or trouble finding or choosing your sprocket please get in touch with our customer support department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made 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 share. Our double single sprockets are produced with hardened tooth and have a black oxide coating for excellent performance and hook corrosion resistance. Stock sizes of double one sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon request. We are able to also supply quick response custom re-bores and MTO specialized double single sprockets because of our quick response 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 dual single sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” or nomenclature to describe their sprockets. Though, through the entire general background of roller chain sprockets almost every manufacture 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 simply “plate sprocket” is definitely a flat 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 is certainly 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 as well as 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 One (these sprockets are created to operate two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” utilize a tapered bushing that is bolted in to the bore that’s machined in the sprocket. When the bushing can be inserted into 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 style of interchangeable bushed sprockets that provides a positive grip on the driven shaft.
Shear Pin sprockets use a shear pin type hub that is bolted to a sprocket to provide an overload device. If the torque ranking can be exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with no 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 your hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket is usually multi strand there will most often be a letter prefix at the beginning of the part quantity.
