Behind the part quantity a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is usually a QD or taper bushed style the center letter for the hub designation is changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is produced from a special material. This designation can be placed in leading of the part quantity or behind, if it’s noted.
Bottom Diameter (BD) – This is the measurement of the diameter of a circle tangent to the bottoms of the tooth spaces.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd number 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 outside diameter is the measurement from the tip of the sprocket tooth across to the corresponding point directly over the sprocket. It is comparatively unimportant as the tooth length is not vital to proper meshing to with the chain. The outside diameter may vary depending 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 another. This diameter should never surpass the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper strength. The dimensional allowance must be made for keyway and arranged screws.
Face Width (T) – Encounter width is limited in its optimum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the correct strength to carry the imposed loads.
Length Thru Bore (L) – The length thru bore should be sufficient to allow a long enough essential 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 train sprockets, and replacing them can cost lots of time and cash. Additionally, the functionality of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is simply as important as selecting the most appropriate chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and are resilient. The roller chain sprockets accessible in our shop include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets satisfy both ANSI and ASME requirements.
We’re positive you’ll be happy when you buy 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 provide us a call. Our knowledgeable staff, superior items, 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 type of each type! Our regular solitary strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are finished with black-oxide for corrosion level of resistance.
To start shopping simply choose what chain size you are using with your sprocket. Next choose the type needed, finally select the preferred tooth count and possible accessories needed, you then are ready to obtain your sprockets! If at any point you have queries or trouble finding or picking your sprocket please contact our customer service department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are designed to run two single-strand type roller chains, that’s where the name “double single” came from. Typically these sprockets are A design but both BTB taper bushed and QD style is available from stock. Our double single sprockets are manufactured with hardened the teeth and have a dark oxide coating for excellent performance and hook corrosion resistance. Share sizes of double one sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon request. 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 store. Something important to 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 dual single sprocket sizes and also have clickable links to the merchandise 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 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 certainly a set sprocket plate-wheel without hubs that extrude on 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 referred to as C-Hub sprockets is 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 past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles as well as several other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are made to operate two single-strands of roller chain aspect parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also referred to as “quick detachable” use a tapered bushing that is bolted in to the bore that is machined in the sprocket. When the bushing is inserted into the sprocket is usually 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 delivers a positive grasp on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to supply an overload gadget. If the torque rating is exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component amount, standardly the chain pitch will be written first, then the hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket is multi strand there will most often be a letter prefix at the beginning of the part number.
