Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is a QD or taper bushed style the center letter for the hub designation can be changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the part quantity if the sprocket is manufactured from a particular material. This designation can be placed in leading of the part quantity or behind, if it is noted.
Bottom Diameter (BD) – This is the measurement of the diameter of a circle tangent to the bottoms of the tooth areas.
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd quantity of teeth can’t be measured directly, caliper diameters are the measurement across the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle followed by the centers of the chain pins since the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The outside diameter is the measurement from the tip of the sprocket tooth across to the corresponding point directly across the sprocket. It really 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 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 must not surpass the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper strength. The dimensional allowance should be designed for keyway and arranged screws.
Face Width (T) – Encounter width is bound in its maximum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimal width is bound to provide the correct strength to transport the imposed loads.
Length Thru Bore (L) – The length thru bore must be sufficient to allow a long enough important to withstand the torque transmitted by the shaft. This also steps 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 replacing them can cost a lot of time and money. Additionally, the functionality of a conveyor or drive depends upon sprocket-chain conversation. Using the proper sprocket is simply 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 satisfy both ANSI and ASME standards.

Our knowledgeable staff, excellent products, and unbeatable prices will be the reasons for our A+ BBB ranking!
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 solitary strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start shopping simply choose what chain size you are employing with your sprocket. Following choose the type needed, finally select the preferred tooth count and feasible accessories needed, you then are ready to get your sprockets! If at any stage you have queries or difficulty finding or choosing your sprocket please get in touch with our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are designed to operate two single-strand type roller chains, that’s where the name “double single” originated from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from share. Our double one sprockets are produced with hardened tooth and have a black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon demand. We can also supply quick response custom re-bores and MTO specialized double single sprockets due to our quick response in-house machine store. Something important to note is that even though these sprockets are double sprockets they will not double-strand roller chain. The charts below show the in-stock dual one sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “terms” or nomenclature to spell it out 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 referred to as A-Plate or just “plate sprocket” is a flat sprocket plate-wheel with no hubs that extrude on 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 certainly 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 begins with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles as well as many other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are made to operate two single-strands of roller chain part parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” use a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing is definitely inserted into the sprocket is definitely 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 delivers a positive grip on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to provide an overload device. If the torque rating is certainly 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 created first, then your hub design or code, and accompanied by the number of teeth the sprocket has. If the sprocket is definitely multi strand there will frequently be considered a letter prefix at the start of the part amount.
