Behind the part number a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket can be a QD or taper bushed design the guts letter for the hub designation is certainly changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the part 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 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 is the circle accompanied by the centers of the chain pins since the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The exterior diameter is the measurement from the tip of the sprocket tooth across to the corresponding stage directly across the sprocket. It 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 kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to another. This diameter must not surpass the calculated diameter of the inside of the chain sidebars.
Optimum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper strength. The dimensional allowance must be designed for keyway and established screws.
Face Width (T) – Encounter width is limited in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal width is bound to provide the correct strength to carry the imposed loads.
Length Thru Bore (L) – The length thru bore must 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 can bring your machinery to a grinding halt. Many devices can’t operate without their drive teach sprockets, and changing them can cost a lot of time and money. Additionally, the functionality of a conveyor or drive depends on sprocket-chain conversation. Using the proper sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and are long lasting.

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 standard solitary strand roller chain sprockets are produced with hardened the teeth (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 shopping simply choose what chain size you are employing with your sprocket. Following choose the type needed, lastly select the desired tooth count and possible accessories needed, then you are ready to get your sprockets! If at any point you have questions or trouble finding or choosing your sprocket please contact our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are designed to operate two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets are A style but both BTB taper bushed and QD design is available from stock. Our double single sprockets are produced with hardened the teeth and have a black oxide coating for superior performance and a slight corrosion resistance. Share sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We can also supply quick reaction custom re-bores and MTO specialty double single sprockets because of our quick response in-house machine shop. Something important to note is that even though these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below show the in-stock double one 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 spell it out their sprockets. Though, through the entire general background of roller chain sprockets nearly every manufacture utilizes four different types of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or simply “plate sprocket” is certainly a set sprocket plate-wheel with no hubs that extrude upon either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also referred to 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 past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles and also various other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Solitary (these sprockets are made to run 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’s bolted in to the bore that’s machined in the sprocket. When the bushing is certainly inserted in to the sprocket can be 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 use a shear pin type hub that’s bolted to a sprocket to provide an overload gadget. If the torque rating is definitely exceeded the shear device 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 component amount, standardly the chain pitch will be created first, then the hub design or code, and accompanied by the number of teeth the sprocket has. If the sprocket is multi strand there will most often be considered a letter prefix at the start of the part number.
