Behind the part number a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is a QD or taper bushed design the center letter for the hub designation is usually changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is produced from a particular material. This designation could 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 areas.
Caliper Diameter – Because the bottom diameter (BD) of a sprocket with odd number of teeth can’t be measured directly, caliper diameters will be 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 since the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside 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 is comparatively unimportant as the tooth size is not essential to proper meshing to with the chain. The outside diameter may vary based on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to some other. This diameter should never surpass the calculated diameter of the inside of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper power. The dimensional allowance should be made for keyway and arranged screws.
Face Width (T) – Face width is limited in its optimum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimal width is limited to provide the correct strength to carry the imposed loads.
Size Thru Bore (L) – The space thru bore must be sufficient to allow a long 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 may bring your machinery to a grinding halt. Many devices can’t operate without their drive teach sprockets, and replacing them can cost considerable time and money. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain conversation. Using the proper sprocket is just as important as deciding on the best 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 so are long lasting.

One 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 regular one strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used superior quality SAE 1045 steel material, and are finished with black-oxide for corrosion level of resistance.
To start shopping simply select what chain size you are employing with your sprocket. Next choose the type needed, lastly select the desired tooth count and feasible accessories needed, you then are ready to obtain your sprockets! If at any stage you have queries or difficulty finding or picking your sprocket please get in touch with our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are made to operate two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from stock. Our double one sprockets are manufactured with hardened tooth and have a black oxide coating for superior performance and hook corrosion resistance. Share sizes of double one sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon demand. We are able to also supply quick response custom re-bores and MTO specialty double single sprockets due to our quick response in-house machine store. Something vital that you note is that even though these sprockets are dual sprockets they will not double-strand roller chain. The charts below display the in-stock double single sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to spell it out their sprockets. Though, throughout the general history of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or simply “plate sprocket” is definitely a flat sprocket plate-wheel without hubs that extrude upon either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also known as 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 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 as well as several 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 made to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “quick detachable” use 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 definitely 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’s bolted to a sprocket to supply an overload device. If the torque ranking is certainly exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured 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 created first, then your hub design or code, and accompanied by the number of teeth the sprocket has. If the sprocket is usually multi strand there will frequently be a letter prefix at the beginning of the part quantity.
