Behind the part amount a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed design the guts letter for the hub designation is usually changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component number if the sprocket is manufactured from a particular material. This designation can be placed in leading 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 – Because the bottom diameter (BD) of a sprocket with odd amount 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 may be the circle accompanied 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 is comparatively unimportant as the tooth duration is not vital to appropriate meshing to with the chain. The outside diameter may vary depending on the type 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 should never surpass the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper strength. The dimensional allowance should be designed for keyway and established screws.
Face Width (T) – Encounter width is limited in its optimum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal width is bound to provide the proper strength to transport the imposed loads.
Duration Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough essential 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 machines can’t operate without their drive train sprockets, and changing them can cost a lot of time and cash. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the proper sprocket is simply 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 engineered to execute well under pressure and are long lasting. 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 standards.
We’re positive you’ll be happy when you buy industrial chain sprockets inside our shop, because they’ll last you a long time.

Our knowledgeable staff, superior items, and unbeatable prices will be the known reasons for our A+ BBB rating!
One STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We share a complete line of each type! Our regular one strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are finished with black-oxide for corrosion level of resistance.
To start shopping simply select what chain size you are using with your sprocket. Following select the type needed, lastly select the preferred tooth count and possible accessories needed, then you are ready to get your sprockets! If at any stage you have queries or difficulty finding or picking your sprocket please contact our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are made to run two single-strand type roller chains, this is where the name “double single” originated from. Typically these sprockets certainly are a style but both BTB taper bushed and QD style is available from share. Our double single sprockets are manufactured with hardened tooth and have a dark oxide coating for excellent performance and a slight corrosion resistance. Stock sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets because of our quick reaction in-house machine store. Something vital that you note is that despite the fact that these sprockets are double sprockets they will not double-strand roller chain. The charts below show the in-stock double single sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to describe their sprockets. Though, through the entire general history 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 known as A-Plate or just “plate sprocket” is definitely a flat sprocket plate-wheel with no 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 called C-Hub sprockets can be 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 will start with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles in addition to 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 One (these sprockets are made to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also called “quick detachable” use a tapered bushing that’s bolted into the bore that’s machined in the sprocket. When the bushing is certainly 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 style of interchangeable bushed sprockets that delivers a positive grasp on the driven shaft.
Shear Pin sprockets use a shear pin type hub that is bolted to a sprocket to provide an overload gadget. If the torque ranking is usually exceeded the shear gadget 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 component quantity, standardly the chain pitch will be created first, then your hub design or code, and accompanied by the number of tooth the sprocket has. If the sprocket is usually multi strand there will most often be considered a letter prefix at the beginning of the part number.
