Behind the part amount 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 style the center letter for the hub designation can be changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the component quantity if the sprocket is manufactured from a special material. This designation can be placed in leading of the part number or behind, if it’s 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 quantity of teeth cannot be measured directly, caliper diameters will be the measurement over the tooth spaces almost 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)
Outdoors Diameter (OD) The outside diameter may be the measurement from the end 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 correct 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) – May be the distance over the hub in one side to some other. This diameter should never go beyond 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 strength. The dimensional allowance must be designed for keyway and established screws.
Face Width (T) – Face width is limited in its maximum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimum 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 an extended enough essential to withstand the torque transmitted by the shaft. This also procedures 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 teach sprockets, and changing them can cost lots of time and cash. Additionally, the efficiency of a conveyor or drive depends upon sprocket-chain conversation. Using the right sprocket is simply as important as deciding on the best chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to execute well under pressure and so 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 fulfill both ANSI and ASME criteria.
We’re positive you’ll be happy when you get industrial chain sprockets inside our store, because they’ll last you a long time. If you’re not sure what sprockets are the ones you will need for your machine, make sure you don’t hesitate to provide us a contact. Our knowledgeable staff, superior items, and unbeatable prices are the known reasons for our A+ BBB rating!
SINGLE 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 standard single strand roller chain sprockets are produced with hardened the teeth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start out shopping simply choose what chain size you are using with your sprocket. Next select the type needed, lastly select the preferred tooth count and feasible accessories needed, you then are ready to get your sprockets! If at any point you have questions or trouble finding or selecting your sprocket please get in touch with our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are created to run 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 design is available from share. Our double single sprockets are manufactured with hardened tooth and have a black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double single sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon demand. We can also supply quick response custom re-bores and MTO specialized double single sprockets because of our quick response in-house machine shop. Something vital that you note is that even though these sprockets are dual sprockets they will not double-strand roller chain. The charts below show the in-stock double solitary sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use 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 various kinds 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 a set sprocket plate-wheel without hubs that extrude on either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also known 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 attached to 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 standard styles as well as various 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 Single (these sprockets are created to run two single-strands of roller chain part parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” make use of a tapered bushing that’s bolted into the bore that is machined in the sprocket. When the bushing can be inserted into the sprocket is usually compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that provides 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 gadget. If the torque rating can be 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 quantity, standardly the chain pitch will be written first, then the hub style or code, and accompanied by the number of tooth the sprocket has. If the sprocket is certainly multi strand there will frequently be considered a letter prefix at the beginning of the part amount.
