Behind the part quantity a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is certainly a QD or taper bushed style the center letter for the hub designation can be changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures may 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 quantity 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 spaces.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd number of teeth can’t 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 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 exterior diameter is 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 correct meshing to with the chain. The outside diameter may vary depending on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to some other. This diameter must not surpass the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper power. The dimensional allowance should be designed for keyway and established screws.
Face Width (T) – Encounter width is bound in its maximum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimal width is bound to provide the correct strength to transport the imposed loads.
Length Thru Bore (L) – The space thru bore must be sufficient to allow a long enough crucial to withstand the torque transmitted by the shaft. This also procedures the stability 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 efficiency of a conveyor or drive depends on sprocket-chain conversation. Using the right sprocket is just 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 designed to execute well under pressure and are resilient. 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 meet both ANSI and ASME specifications.
We’re positive you’ll end up being happy when you buy industrial chain sprockets in our store, because they’ll last you a long time.

Our knowledgeable staff, excellent products, and unbeatable prices are 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 stock a complete line of each type! Our standard single strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used superior 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. 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 problems finding or picking your sprocket please contact our customer service 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, this is where the name “double single” originated from. Typically these sprockets are A design but both BTB taper bushed and QD style is available from share. Our double single sprockets are produced with hardened teeth and have a black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes can be manufactured upon ask for. We are able to also supply quick response custom re-bores and MTO specialty double single sprockets because of our quick reaction in-house machine store. Something vital that you note is that even though these sprockets are double sprockets they’ll not double-strand roller chain. The charts below display the in-stock double solitary sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” or nomenclature to describe their sprockets. Though, throughout the general history of roller chain sprockets almost every manufacture utilizes four different types of sprockets and has adopted the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or simply “plate sprocket” is a flat sprocket plate-wheel with no hubs that extrude on either side.
Style B, also known 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.
Design 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 previous 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 design sprockets, also referred to as “quick detachable” use a tapered bushing that’s bolted into the bore that’s machined in the sprocket. When the bushing is usually inserted into 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 style of interchangeable bushed sprockets that delivers a positive hold 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 device. If the torque rating is definitely exceeded the shear gadget 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 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 most often be considered a letter prefix at the start of the part quantity.
