Behind the part quantity 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 definitely changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the part number if the sprocket is manufactured from a particular material. This designation could be placed in the front of the part number 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 level diameter (BD) of a sprocket with odd amount 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 is the circle followed 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 may be the measurement from the end of the sprocket tooth across to the corresponding point directly across the sprocket. It is comparatively unimportant as the tooth size is not vital to proper 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 from one side to another. This diameter should never exceed the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper power. The dimensional allowance must be made for keyway and set screws.
Face Width (T) – Encounter width is limited in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is bound to provide the correct strength to carry the imposed loads.
Size Thru Bore (L) – The space thru bore should be sufficient to allow an extended enough key to withstand the torque transmitted by the shaft. This also measures 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 machines can’t operate without their drive train sprockets, and changing them can cost considerable time and cash. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are manufactured to perform well under pressure and are long lasting. The roller chain sprockets for sale in our store 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.
We’re positive you’ll end up being happy when you get industrial chain sprockets in our store, because they’ll last you quite 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 give us a call. Our knowledgeable staff, superior products, and unbeatable prices will be the known reasons for our A+ BBB rating!
Solitary 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 standard solitary strand roller chain sprockets are manufactured with hardened tooth (for tooth counts under 30), used premium 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 employing with your sprocket. Following select the type needed, lastly select the desired tooth count and feasible accessories needed, you then are ready to get your sprockets! If at any stage you have questions or difficulty finding or picking your sprocket please get in touch with our customer support department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are created to operate two single-strand type roller chains, that’s where the name “dual single” originated from. Typically these sprockets are A style but both BTB taper bushed and QD style is available from share. Our double solitary sprockets are manufactured with hardened tooth and have a dark oxide coating for excellent performance and hook corrosion resistance. Share sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon demand. We are able to also supply quick response custom re-bores and MTO specialized double single sprockets due to our quick response in-house machine shop. 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 display the in-stock double solitary sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “terms” or nomenclature to describe their sprockets. Though, through the entire general background of roller chain sprockets nearly 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 just “plate sprocket” is a flat sprocket plate-wheel with no 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 usually 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 standard styles along with various other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to operate two single-strands of roller chain aspect parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” make use of a tapered bushing that is bolted in to the bore that’s machined in the sprocket. When the bushing is certainly inserted in to the sprocket is certainly 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 hold 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 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 amount, standardly the chain pitch will be written first, then the hub style or code, and followed by the number of the teeth the sprocket has. If the sprocket can be multi strand there will frequently be considered a letter prefix at the start of the part number.
