Behind the part number 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 style the guts letter for the hub designation is definitely changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the part quantity if the sprocket is manufactured from a particular material. This designation could be placed in the front of the part amount 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 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 may be the measurement from the end of the sprocket tooth across to the corresponding point directly across the sprocket. It is comparatively unimportant as the tooth length is not essential to correct meshing to with the chain. The exterior diameter may vary depending on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub in one side to another. This diameter must not surpass the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper strength. The dimensional allowance should be made for keyway and set screws.
Face Width (T) – Encounter width is bound in its maximum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimum width is limited to provide the proper strength to carry the imposed loads.
Length Thru Bore (L) – The length thru bore should 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 can bring your machinery to a grinding halt. Many devices can’t operate without their drive train sprockets, and changing them can cost a lot 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 selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are manufactured to execute well under pressure and so are long lasting. The roller chain sprockets for sale in our shop 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 requirements.
We’re positive you’ll end up being 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 styles of sprockets for single strand roller chain. We stock a complete line 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 metal material, and are completed with black-oxide for corrosion level of resistance.
To start shopping simply choose what chain size you are employing with your sprocket. Next choose the type needed, finally select the desired tooth count and possible accessories needed, then you are ready to obtain your sprockets! If at any point you have queries or trouble finding or selecting your sprocket please contact our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to run two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets are A style 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 excellent performance and hook corrosion resistance. Stock sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon request. We can also supply quick response custom re-bores and MTO specialty double single sprockets because of our quick response in-house machine store. 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 product 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 almost every manufacture utilizes four different types of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or just “plate sprocket” is a set 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 referred to as C-Hub sprockets is definitely a sprocket with a hub that extrudes on both sides.
Style 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 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 created to operate two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also referred to as “quick detachable” utilize a tapered bushing that is bolted into the bore that is machined in the sprocket. When the bushing is definitely inserted in to the sprocket is usually 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 delivers 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 device. If the torque rating is definitely exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation without 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 your hub design or code, and accompanied by the number of tooth the sprocket has. If the sprocket can be multi strand there will frequently be considered a letter prefix at the beginning of the part number.
