Behind the part amount a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is usually a QD or taper bushed style the guts letter for the hub designation is usually changed to represent so.
Regular 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 can be placed in leading of the part amount 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 spaces.
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd amount 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 because the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The exterior diameter may be the measurement from the end of the sprocket tooth across to the corresponding point directly over the sprocket. It really is comparatively unimportant as the tooth duration is not essential to appropriate meshing to with the chain. The outside diameter may vary based on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub from one side to some other. This diameter should never go beyond 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 must be made for keyway and set screws.
Face Width (T) – Face width is bound in its optimum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the proper strength to transport the imposed loads.
Size Thru Bore (L) – The space thru bore must be sufficient to allow an extended enough crucial 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 may bring your machinery to a grinding halt. Many devices can’t operate without their drive train sprockets, and replacing them can cost considerable time and cash. Additionally, the performance of a conveyor or drive depends upon sprocket-chain interaction. 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 manufactured to execute well under pressure and so are resilient. 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 both ANSI and ASME standards.
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 will be the ones you will need for your machine, please don’t hesitate to give us a contact. Our knowledgeable staff, excellent products, and unbeatable prices are 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 type of each type! Our regular one strand roller chain sprockets are produced with hardened teeth (for tooth counts under 30), used high quality quality SAE 1045 metal material, and are completed with black-oxide for corrosion level of resistance.
To start out shopping simply choose what chain size you are using with your sprocket. Following select the type needed, lastly select the preferred tooth count and feasible accessories needed, then you are ready to obtain your sprockets! If at any stage you have queries or trouble finding or choosing your sprocket please get in touch with our customer support department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are made to run two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets certainly are a style but both BTB taper bushed and QD design is available from share. Our double one sprockets are manufactured with hardened the teeth 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 could be manufactured upon demand. We can also supply quick reaction custom re-bores and MTO specialized double single sprockets due to our quick response in-house machine shop. Something important to note is that even though these sprockets are double sprockets they’ll not double-strand roller chain. The charts below display the in-stock dual single sprocket sizes and 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 background of roller chain sprockets almost every produce utilizes four various kinds of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or simply “plate sprocket” is certainly a flat 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 on one side.
Style C, also referred to as C-Hub sprockets is usually 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 many other styles upon request.
D – Dual 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 one another)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” utilize a tapered bushing that is bolted in to the bore that is machined in the sprocket. When the bushing is usually inserted in to the sprocket is 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 delivers a positive grasp on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that is bolted to a sprocket to supply an overload gadget. If the torque ranking is exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are produced 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 followed by the number of tooth the sprocket has. If the sprocket is definitely multi strand there will most often be a letter prefix at the beginning of the part number.
